11 CHAPTER 1 Flasher ATE overview

1.1 Flasher ATE overview

Flasher ATE is a programming tool for micro controllers with on-chip or external flash memory. Flasher ATE is designed for programming flash targets in stand-alone mode or remote controlled via a PC.

Flasher ATE connects to a PC using the USB / Ethernet / RS232 interface, running Windows 7, Windows 8 or Windows 10. In stand-alone mode, Flasher ATE can be driven by telnet interface, or via the RS232 interface (handshake control or ASCII interface). Flasher ATE has a 20-pin connector, which supports various interfaces. JTAG or SWD are supported natively. Other interfaces are available via adapters, sold separately.

1.1.1 Features of the Flasher ATE

• Supports up to 10 individual channels.

• Stand-alone programmer (Once set up, Flasher can be controlled without the use of a PC program).

• Flexible power supply (USB, DC).

• 128 MB memory for storage of target program on each module.

• Data files can be updated via the integrated FTP server.

• Various target interfaces

Supported cores

ARM7/ARM9/Cortex-M, AVR MEGA, AVR Tiny, AVR XMEGA, MSP430, Power PC e200z0, PIC16, PIC18, RX610, RX621, RX62N, RX62T, RX64, RH850, STM8

Supported

up to 300 Kbytes/ second

1.1.2 Working environment

General

The Flasher ATE can be operated from a PC with an appropriate software like J-Flash or in stand-alone mode.

Host System

IBM PC/AT or compatible CPU: 486 (or better) with at least 128MB of RAM, running Microsoft Windows 7, Windows 8, or Windows 10. It needs to have a USB, Ethernet, or RS232 interface available for communication with the Flasher ATE.

Power supply

The system is powered via the mainboard. The supply voltage needs to be in the range from 4.8V to 5.25V. If the supply voltage exceeds these limits, the mainboard immediately shuts down the power supply for the connected modules for safety reasons.

Current consumption (typical)

Mainboard

5V DC connector (VMAIN)

USB (not applicable for hardware V1.1)

100 mA (no flasher module connected, no USB, no Ethernet)

180 mA (no flasher module connected, USB and Ethernet connected)

100 mA (no flasher module connected, no USB, no Ethernet)

Page 12

12 CHAPTER 1 Flasher ATE overview

Chapter 2 Working with the Flasher ATE

This chapter describes functionality and how to use the Flasher ATE.

Page 17

17 CHAPTER 2 The Flasher ATE

2.1 The Flasher ATE

The Flasher ATE has been designed to be used in conjunction with automated test equipment (ATE). It is modular and scalable from 1 to 10 individual programming modules.

Page 18

18 CHAPTER 2 The Flasher ATE

2.1.1 Power supply

2.1.1.1 Mainboard and module power supply

The Flasher ATE mainboard and the modules are powered either by a dedicated power connector (VMAIN) or by USB. The power source may not be switched while the Flasher ATE is running.

Page 19

19 CHAPTER 2 The Flasher ATE

2.1.1.2 Target power supply

For target power supply, the Flasher ATE offers two options. Additionally, a power discharge option is available. The target is electrically isolated from the mainboard’s power supply.

The first option is to use the VTGT connector. It is possible to provide any voltage between 3 and 15V, however the target interface is limited to 1.2V - 5V signal voltage. The VTGT connector is directly coupled to the target, so any electrical isolation has to be done in the external power supply.

The second option is to use the module’s internal power source VCC5V, which is able to deliver up to 100mA to the target.

The power discharge option applies, when the operation has finished. A 39 ohms resistor is used to discharge any remaining charge on the target’s capacitors. As the thermal load of the resistor is limited, the target’s capacity may not exceed 27mF at 15V or 250mF at 5V supply voltage.

Note

Flasher ATE programming modules provide functional isolation among each other.

Do not use with hazardous voltages to avoid risk of electrical shock and fire.

Page 20

20 CHAPTER 2 Setting up the IP interface

2.2 Setting up the IP interface

The Flasher ATE comes with an additional Ethernet interface to communicate with the host system. The Flasher ATE has a built-in webserver which allows some basic setup of the emulator, e.g. configuring a default gateway which allows using it even in large intranets.

2.2.1 Connecting for the first time

When connecting Flasher ATE for the first time, it attempts to acquire an IP address via DHCP. The recommended way for finding out which IP address has been assigned to Flasher ATE is to use the J-Link Configurator. The J-Link Configurator is a small GUI-based utility which shows a list of all emulators that are connected to the host PC via USB and Ethernet.

For more information about the J-Link Configurator, please refer to UM08001_JLink.pdf (JLink / J-Trace user guide), chapter Setup, section J-Link Configurator.

The picture shows the J-Link Configurator with the detected Flasher ATEs. Select the one you want to configure.

You may configure your Flasher ATE to use your preferred IP setting. This is done by selecting the Flasher ATE in the list, opening the context menu with a right click on the list entry, and choosing Configure from the context menu. Enter your required IP settings in the dialog box that opens up, e.g. as shown in the next picture. Confirm the IP settings by pressing OK.

Page 21

21 CHAPTER 2 Setting up the IP interface

Note

If your computer is connected to a wireless LAN, some routers do not forward the broadcast messages used to find the Flasher ATE from LAN to WLAN. In that case either use a LAN connection for your computer or connect the Flasher ATE via USB to your computer and choose the Flasher ATE in the list of connected USB devices.

Page 22

22 CHAPTER 2 Operating modes

2.3 Operating modes

The Flasher ATE is able to operate in the following modes:

• remote controlled mode

• handshake mode

Definition of remote-controlled mode

The remote-controlled mode is the recommended mode of operation. The Flasher ATE will receive its commands via an interface and will report the results to the caller. That is how the caller can check if the programming was done successfully or not.

Definition of handshake mode

The stand-alone mode is controlled the 3 handshake lines.

2.3.1 Remote-controlled mode

The remote-controlled mode provides a way to integrate the Flasher ATE into a production environment and control it via a communication protocol. Therefore two physical interfaces can be used: ethernet or RS232. In this setup, the Flasher ATE provides detailed status information which can be used to verify the success of the programming sequence, optimize the production setup, and identify errors. The following picture shows the Flasher ATE integration into a production environment.

Page 23

23 CHAPTER 2 Operating modes

Page 24

24 CHAPTER 2 Operating modes

In order to use Flasher in “remote-controlled mode”, it has to be configured first, as described in Setting up Flasher for remote-controlled mode on page 31.

2.3.2 Handshake mode

The handshake mode provides a simple way to start the flashing of the connected targets. The pins 1, 4, 5 and 7 of the RS232 connector can be used to e.g. connect a start button and two indicator LEDs for programming control. The following picture show the Flasher ATE internal logic and the signal states during the programming sequence.

Note

The Flasher ATE will not provide any detail error codes during this mode. We recommend to use the remote controlled mode for mass production.

In order to use Flasher in “handshake mode”, it has to be configured first, as described in Setting up Flasher for handshake mode on page 33.

Page 25

25 CHAPTER 2 LED status indicators

2.4 LED status indicators

The Flasher ATE uses different LEDs, see the following tables.

26 CHAPTER 2 Flasher ATE storage

2.5 Flasher ATE storage

The Flasher ATE stores the configuration and programming data on its internal memory. This can be accessed with an FTP-client. Each module has capacity of approximately 126MB for data and configuration files.

The files are stored on the Flash Modules. They are mounted via the mainboard in subfolders named “Module.xxx”, with xxx being the number in the flash module chain, e.g. “Module.001” for the first module. The first module next to the mainboard is assigned the number one and the last module is assigned the number ten.

While the transceiver is switched off, status messages from the module are sent out to the terminal. If the transceiver is active, incoming data on pin 17 on the debug interface is sent to the TCP connection, and incoming data on the TCP connection is sent to pin 5 on the debug interface. The parameters for the UART configuration are handed over when activating the transceiver mode with the command #TERMINAL <module(s)> <Baudrate>,<Databit- s>,<Parity>,<Stopbits> on page 67.

Note

The transceiver cannot be enabled while the module is programming. Also programming, erasing etc. can not be started if the transceiver mode is active.

The UART to TCP transceiver supports:

• baud rate: 2,400 up to 115,200,

• parity: none, even and odd,

• full duplex mode.

2.7 Log files

The Flasher ATE writes log files. Each flash module writes the success or error into the log file.

The log files are stored in the module folder of the corresponding flash module. They can be downloaded using the FTP service.

2.8 Newline encoding

In general, for all patch files, init files etc. Flasher ATE supports both newline encodings:

• Windows: \r\n

• Unix/Mac: \n

All parser functionality etc. are written to be independent from the host operating system.

mode

3.1 Setting up Flasher ATE for remote-controlled mode

In order to set up the Flasher ATE for the remote-controlled mode it needs to be configured once using the J-Flash software. For more information about J-Flash, please refer to the J-Flash User Guide.

After starting J-Flash, open the appropriate J-Flash project for the target the Flasher ATE shall be configured for, by selecting File -> Open Project. If J-Flash does not come with an appropriate sample project for the desired hardware, a new project needs to be created by selecting File -> File -> New Project.

After the appropriate project has been opened / created, the data file which shall be programmed needs to be loaded, by selecting File -> Open. After this J-Flash should look like in the screenshot below.

Page 32

32 CHAPTER 3 Setting up Flasher ATE for remote-controlled

mode

Before downloading the configuration (project) and program data (data file) to the Flasher ATE, both files need to saved to disk by File -> Save Flasher Config File and File -> Save Flasher Data File.

Next, upload the configuration file and the data file with an FTP client into the Flasher ATE module folder(s). If the J-Flash tool also generates a .pex file this also needs to be loaded into the module folder(s). But it must be located in a subfolder which must be named like your project. E.g. if your project is named MyTest with the project files MyTest.cfg and MyTest.dat, then the subfolder must be named MyTest.

From now on, the Flasher ATE can be used in stand-alone mode (without host PC interaction) for stand-alone programming.

Page 33

33 CHAPTER 3 Setting up Flasher ATE for handshake mode

3.2 Setting up Flasher ATE for handshake mode

In order to set up the Flasher ATE for the handshake mode it needs to be configured once using the J-Flash software. For more information about J-Flash, please refer to the J-Flash User Guide.

Please follow the steps in chapter Setting up Flasher for remote-controlled mode on page 31 first.

In addition you have to tell the Flasher ATE which project shall be programmed. Therefore you can directly edit the FLASHER.ini file in each modules folder, or connect to the Flasher ATE and use the “#select” command.

The FLASHER.ini file might look like as follows if your project is named MyTest:

[FILES] DataFile = "MyTest.DAT" ConfigFile = "MyTest.CFG"

From now on, the Flasher ATE can be used in stand-alone mode (without host PC interaction) for stand-alone programming.

Page 34

34 CHAPTER 3 Universal Flash Loader mode

3.3 Universal Flash Loader mode

As an alternative to the stand-alone mode, configured via J-Flash, there is the Universal Flash Loader mode. While the normal stand-alone mode relies on using the debug interface of the device, the Universal Flash Loader mode uses device or vendor specific programming interfaces and protocols and therefore it is independent of the CPU core.

3.3.1 Preparing manually

The Universal Flash Loader uses an initialization file (*.UNI), a device specific flash programming algorithm (*.PEX) and a data file (*.HEX, *.MOT, *.BIN or *.DAT).

3.3.1.1 Configuration

The initialization file basically is split into three parts. The first part, the section [DEVICE], controls the generic behavior of the Universal Flash Loader. It specifies which protocol driver and data file to use. It allows enabling and configuring target power and it defines which actions to perform. The second part consists of one or more [BANKx] sections, which contain information about the memories. The third part, the section [CONFIG], includes configuration settings for the protocol driver.

An .ini file might look as follows:

[OPTIONS] TargetPower = "0" ChipErase = "0"

[TASKS] CheckBlank = "1" Erase = "1" Program = "1" Verify = "1" Secure = "1"

[DEVICE] Algo = "RL78.PEX" Data = "ALL_6k.mot" Offset = "0x00000000"

[BANK0] ; Code Flash Base = "0x00000000" Size = "0x00004000" Sect = "0x00000400"

[BANK1] ; Data Flash Base = "0x000F1000" Size = "0x00000800" Sect = "0x00000400"

[CONFIG] BaudRate = "1000000" ClearConfigOnConnect = "0x00" Security = "0xFF" ShieldStart = "0x0000" ShieldEnd = "0x000F"

[OPTIONS] TargetPower

If set to a value >0, power is applied to the target. The value defines the delay (in ms) after enabling the target power supply and before starting to communicate with the target.

Page 35

35 CHAPTER 3 Universal Flash Loader mode

ChipErase

If set to 1, the chip erase function is called for erasing the chip.

Note

Do not enable this setting if the flash programming algorithm does not support chip erase.

[TASKS] CheckBlank

Defines if a blank check should be performed before erasing a sector.

Erase

Defines if the sector should be erased before programming.

Program

Defines if the sector should be programmed.

Verify

Defines if the sector should be verified after programming.

Secure

Defines if the device should be secured or protected against read-out after verifying.

[DEVICE] Algo

File name of the flash programming algorithm. This file is provided by SEGGER and will typically support a series of devices.

Data

File name of the data file to program. The flasher supports the Flasher DTA, the Intel HEX, the Motorola S-Record and the binary file format. Flasher DAT files are generated by J-Flash and offer high performance together with high flexibility. The other file formats produce a small overhead, because they have to be parsed before the data can be programmed.

Offset

Offset to apply when programming a binary data file. Unless specified differently, binary files start at offset 0x00000000.

[BANKx]

x blocks with configuration data for the flash banks. All three parameters (Base, Size and Sect) are mandatory.

Base

Base address of the flash bank.

Size

Total size of the flash bank.

Sect

Sector size of the flash bank.

Page 36

36 CHAPTER 3 Universal Flash Loader mode

[CONFIG]

This section includes specific configuration data for the flash programming algorithm. There are no general parameters.

Note

The data file must be organized in ascending address order. Gaps can be included. But descending addresses will result in programming errors. You can sort the data files by loading them into the J-Flash tool and saving it as a new file.

Chapter 4 Serial number handling

This chapter describes how the Flasher ATE deals with serial numbers.

Page 47

47 CHAPTER 4 Serial number programming

4.1 Serial number programming

The Flasher ATE supports programming of serial numbers. In order to use the serial number programming feature, the J-Flash project to be used as well as some files on the Flasher ATE (depending on the configuration) need to be configured first.

In general, Flasher ATE supports two ways of programming a serial number into the target:

1. Programming continuous serial numbers. Serial number is 1-4 bytes in size. Start serial number, increment, serial number size and address is configured in the J-Flash project.

2. Programming custom serial numbers from a serial number list file. Start line into serial number list file to get next serial number bytes, line increment, serial number size and address is configured in J-Flash project. Serial number list file needs to be specified and created by user.

Some generic information on how to setup Flasher ATE & the J-Flash project for serial number programming are provided below.

Note

Full serial number programming support has been introduced with V4.51d of the JFlash software and the Flasher firmware that comes with it.

4.1.1 Serial number settings

In order to enable the programming of serial numbers in stand-alone mode, the J-Flash project has to be configured to enable programming a serial number at a specific address. This is done by enabling the Program serial number option as shown in the screenshot and table below:

Setting Meaning

Address The address the serial number should be programmed at.

The length of the serial number (in bytes) which should be programmed.

Len

If no serial number list file is given, J-Flash allows to use a 1-4 byte serial number. In case 8 is selected as length, the serial number and its complementary are programmed at the given address.

Page 48

48 CHAPTER 4 Serial number programming

Setting Meaning

In case a serial number list file is given, Flasher ATE will take the serial number bytes from the list file. If a serial number in the list file does not define all bytes of Len the remaining bytes are filled with 0s. No complements etc. are added to the serial number.

In case no serial number list file is given, Next SN is the next serial number which should be programmed. The serial number is always stored in little endian format in the flash memory.

Next SN

Increment Specifies by how much Next SN is incremented.

In case a serial number list file is given, Next SN describes the line of the serial number list file where to read the next serial number bytes from. Flasher ATE starts counting with line 0, so in order to start serial number programming with the first line of the SNList.txt, Next SN needs to be set to 0.

4.1.2 Continuous Serial numbers

The Flasher ATE can generate serial numbers. Therefore the project can be configured to use teh serial number feature (see on page 47). The Flasher ATE will use the first serial number for the first programmed device. Then the increment is added to the serial number and this is used for the next programming sequence. The next serial number is stored in the SERIAL.TXT file on each flash module. So the serial number is also power cycle safe. If the file is missing at start up time, the number 0 is used for the first target.

To avoid doubled serial numbers with the Flasher ATE using more than one flash module there are two options:

• Use an increment of the channel number, e.g. if you have 5 flash modules, use an increment of 5 as well as 5 different SERIAL.TXT files at beginning of production.

• Use different serial number areas, e.g. if you have 5 flash modules, use an increment of 1 as well as 5 different SERIAL.TXT files at beginning of production. For the first module, use the range from 1 to 1000, for the second 1001 to 2000 and so on.

The SERIAL.TXT file contains the value Next SN in ASCII notation, e.g. 1234 if the next serial number is 1234.

Note

The serial number in SERIAL.TXT will also be incremented serial number programming is disabled, to make sure that for the Flasher ATE logfile there is a reference for which programming cycle passed and which did not. As long as serial number programming has not been enabled in the J-Flash project, Flasher ATE does not merge any serial number data into the image data to be programmed.

4.1.3 Serial number list file

In order to program custom serial numbers which can not be covered by the standard serial number scheme provided by J-Flash (e.g. when programming non-continuous serial numbers or having gaps between the serial numbers), a so called serial number list file needs to be created by the user.

The SERIAL.TXT file needs to contain the values for the serial numbers in ASCII notation. Each line in the file must contain one serial number.

Example

An 8-byte serial number should be programmed at address 0x08000000.

It should be programmed as follows in the memory:

0x08000000: 0x01 0x02 0x03 0x04 0x55 0x66 0x77 0x88

Page 49

49 CHAPTER 4 Serial number programming

The associated serial number list in teh file should look as follows:

0102030455667788

The number of bytes to read per line is configured via the Len option in J-Flash. For more information, please refer to Serial number settings on page 47.

Which line Flasher will read at the next programming cycle is configured via the Next SN option in J-Flash. For more information, please refer to Serial number settings on page 47. In this case, Next SN needs to be set to 0, since programming should be started with the serial number bytes defined in the first line of the file.

Note

If the number of bytes specified in a line of the serial number list file is less than the serial number length defined in the project, the remaining bytes are filled with 0s by Flasher ATE.

Note

If the number of bytes specified in a line of the serial number list file is greater than the serial number length defined in the J-Flash project, the remaining bytes will be ignored by Flasher ATE.

4.1.4 Programming process

The Flasher ATE will increment the serial number in SERIAL.TXT by the value defined in

Increment after each successful programming cycle.

For each programming cycle, the FLASHER.LOG file on the Flasher ATE flash module is updated and contains the value from SERIAL.TXT that has been used for the programming cycle.

Note

The serial number in SERIAL.TXT will also be incremented if serial number programming is disabled, to make sure that for the Flasher ATE logfile there is a reference for which programming cycle passed and which did not. As long as serial number

Page 50

50 CHAPTER 4 Serial number programming

programming has not been enabled in the J-Flash project, the Flasher ATE does not merge any serial number data into the image data to be programmed.

4.1.5 Sample setup

Below, a small example is given on how to setup Flasher ATE for serial number programming. In the following example, 4-byte serial numbers starting at 1234567 (0x12D687) shall be programmed at address 0x08001000.

Defining serial number address, length and start value

In the J-Flash project the following needs to be defined:

• Address is 0x08001000

• Next SN is 1234567

• Increment is 1

• Len is 4 (bytes)

Page 51

51 CHAPTER 4 Serial number programming

Downloading configuration, data and serial number to the Flasher ATE.

After setting up the rest of the configuration (Target interface etc.) and selecting an appropriate data file, the configuration, data, and serial number file needs to be downloaded into Flasher ATE via FTP client.

Page 52

52 CHAPTER 4 Limiting the number of programming cycles

4.2 Limiting the number of programming cycles

The Flasher ATE provides a mechanism to limit the number of programming cycles that can be performed in stand-alone mode with the configuration that is stored on the Flasher ATE. To make use of this feature, a file called Cntdown.txt needs to be placed on the Flasher ATE module folder. This file simply contains a decimal number (32-bit unsigned integer) that describes how many programming cycles can be performed with the current setup.

Note

The number in the Cntdown.txt is only updated on a successful programming cycle. Programming cycles that failed do not affect the Cntdown.txt.

4.2.1 Changed fail/error LED indicator behavior

In case a Cntdown.txt is found at boot time, the fail/error LED of Flasher behaves different from normal. If the number of programming cycles left is 10 or below, the following will happen:

• The red error/fail LED will be lit for 1 second

• After this, it will blink/toggle x times @ 5 Hz, indicating the number of programming cycles left. (blinking 5 times for 5 cycles left, …)

Page 53

Chapter 5 Patch data file

This chapter describes how the Flasher ATE can patch data files.

Page 54

54 CHAPTER 5 Patch file support

5.1 Patch file support

In stand-alone mode the Flasher ATE supports patch files which allows to patch the content of the data to be programmed. Before starting programming process in stand-alone mode, the Flasher ATE will look for a file named Patches.txt being present on the Flasher ATE module. This file includes the patches. If this file is present, the number in Serial.txt describes the line number of the Patches.txt that will be used for the current cycle (line counting starts at 0).

Each line in the Patches.txt can hold up to 4 patches, where each patch can be up to 32 bytes in length.

Syntax

Each line begins with <NumPatches> followed by each patch <Addr>,<NumBytes>:<Data> in sequence and separated by commas. So the syntax for <NumPatches> = 4 would be as follows:

<NumPatches>,<Addr>,<NumBytes>:<Data>,<Addr>,<NumBytes>:<Data>,<Addr>, <NumBytes>:<Data>,<Addr>,<NumBytes>:<Data>\r\n

Find below a table which describes each parameter.

Parameter Description

<Addr>

<Data>

Describes the number of patches in this patch line. Max. value is 4.

Describes the address to be patched. Value is expected in hex.

Number of bytes for the current patch. Max. value is 20h (32 in decimal). Value is expected in hex.

Describes the data to be patched. <Data> is always expected as 2 hexadecimal characters per byte.

Note

All values are expected in hexadecimal format (hex). <Data> section is always preceded by “:”, not “,”.

Example

Please find below a sample sequence which clarifies the usage of patch files.

Patches.txt, which is located on the Flasher, contains the following line:

3,100025,3:AABBCC,100063,2:DDEE,100078,1:FF

Serial.txt contains a “0” which forces the Flasher to use line 0 from Patches.txt.

After starting the programming cycle, the following data will be patched: Addr 0x100025: 3 byte 0xAA 0xBB 0xCC

Addr 0x100063: 2 byte 0xDD 0xEE Addr 0x100078: 1 byte 0xFF

Single patch via RS232 or Telnet

Alternatively, you can start a programming cycle with patch data that is only valid for this one cycle (no need for a Patches.txt file):

Send the #AUTO PATCH <module> <NumPatches>,<Addr>,<NumBytes>:<Data>

command via the Flasher ATE ASCII interface. The parameters have the same function as described in the table above.

5.2 FTP server connection

Page 56

Chapter 6 FTP Server

This chapter describes the FTP server features.

Page 57

57 CHAPTER 6 FTP server connection

6.1 FTP server connection

The FTP server provides easy access to the files on the internal file system. The server supports a maximum of 2 simultaneous connections and works with all common FTP clients.

For the Flasher ATE, the FTP server is the only way to access files on the modules. Here the root directory is a virtual directory and cannot be written to. It contains a subdirectory for each module. The module next to the mainboard is the first one and is mounted as MODULE.001 and the last module is mounted as Module.010.

The FTP server allows you to upload or download the target configuration and data files. The Flasher ATE setup files can also be uploaded or downloaded to the module folders.

The Flasher ATE writes a log file for executed operations. This can be found in the modules folder and downloaded from there.

Note

The file system on the Flasher ATE supports only 8.3 file names. Meaning 8 characters for the name and 3 characters for the file extension.

The IP setup is described here: Setting up the IP interface on page 20.

6.1.1 Access data

Anonymous access to the FTP server is limited to read-only access to the file system. For write access, special login credentials have to be used:

Note

The access data for read/write access can not be modified and it is intended to be used only as a convenience feature to avoid unintended modification of the Flasher’s file system. It is not meant as a security feature.

59 CHAPTER 7 Web server features

7.1 Web server features

The Flasher ATE comes with a built-in web server, which provides a web interface for information and network configuration. For the network, the IP address settings can be changed and a nick name can be assigned to the device.

Additionally, the web interface provides information about the status of the integrated operating system, the IP stack and the target hardware. The Flasher ATE’s web interface furthermore allows monitoring of the individual modules.

The IP setup is described here: Setting up the IP interface on page 20.

Page 60

Chapter 8 Remote control

This chapter describes how to control Flasher via the 9-pin serial interface connector or via the integrated Telnet interface.

Page 61

61 CHAPTER 8 Overview

8.1 Overview

There are three ways to remote control the Flasher ATE operation:

• Via Handshake lines: 3 lines on the serial interface are used: 1 line is an input and can be used to start operation, 2 lines are outputs and serve as busy and status signals.

• Terminal communication via RS232.

• Terminal communication via Telnet.

Page 62

62 CHAPTER 8 Handshake control

8.2 Handshake control

The Flasher ATE can be remote-controlled by automated testers without the need of a connection to a PC. Therefore the Flasher ATE is equipped with additional hardware control functions, which are connected to the SUBD9 male connector, normally used as RS232 interface to PC.

The following diagrams show the internal remote control circuitry of Flasher:

Pin No. Function Description

A positive pulse of any voltage between 5 and 30V with duration of min. 30 ms starts “Auto” function

1 START

4 BUSY

5 GND Common Signal ground.

7 OK

Note

As the Flasher ATE is a modular system, using the handshake remote control START always triggers the “Auto” function of every connected module. The BUSY line is signaled as long as any module is still busy and the OK line only reports “OK” in case of every module has successfully completed the operation. We recommend using the

(Clear / Program / Verify) on falling edge of pulse. The behavior of the “Auto” function depends on the project settings, chosen in J-Flash at the Produc- tion tab.

As soon as the “Auto” function is started, BUSY becomes active, which means that transistor is switched OFF.

This output reflects result of last action. It is valid after BUSY turned back to passive state. The output transistor is switched ON to reflect OK state.

ASCII command interface, described in the next chapter, for the Flasher ATE as it gives better remote control capabilities.

Page 64

64 CHAPTER 8 ASCII command interface

8.3 ASCII command interface

8.3.1 Introduction

Once set up using J-Flash, the Flasher ATE can be driven by any application or just a simple terminal using ASCII commands.

Every known command is acknowledged by the Flasher ATE and then executed. After command execution, the Flasher ATE sends an ASCII reply message.

Note

There are situations where the execution of a known command is rejected with #NACK:ERRxxx if Flasher ATE is currently busy and the received command is not allowed to be sent while Flasher ATE is busy

8.3.2 General command and reply message format

• Any ASCII command has to start with the start delimiter #.

• Any ASCII command has to end with simple carriage return (’\r’, ASCII code 13).

• Commands can be sent upper or lower case.

8.3.3 General usage

Reply messages must be considered in each case. In general, a new command must not be sent before a reply for the last one has been received. The least the “#ACK” needs to be received by the controlling application before sending a new command for a flash module not yet executing a command.

For the Flasher ATE, all commands triggering a flash programming function (#AUTO, #CAN- CEL, #ERASE, #PROGRAM, #VERIFY) may be used for other modules, before the current operation has been finished. Please note that in this case the overall finish indicator “#DONE” will be sent when all commands have been executed.

When a flash programming function has finished, the debug logic of the MCU is disabled (power down) and the target interface of the module is switched off (tristated).

8.3.4 Settings for ASCII interface via RS232

Flasher is driven via a RS232 serial port with the following initial interface settings:

• 9600 baud

• 8 data bits

• no parity

• 1 stop bit

The baud rate can be changed by using the #BAUDRATE command.

8.3.5 Settings for ASCII interface via Telnet

A client application can connect to the Flasher ATE via Telnet on port 23. Find below a screenshot of Flasher which is remote controlled via Telnet:

Page 65

65 CHAPTER 8 ASCII command interface

Some additional data are transferred via an additional telnet connection (target channel) for each module. These data may be helpful for the project setup. In the normal operation these channels are not required.

8.3.6.1 Commands to the Flasher

8.3.6.1.1 Command #AUTO

The #AUTO command behaves exactly as the external remote control input. Usually, the following command sequence will be performed when receiving the #AUTO

command:

• The Flasher ATE erases the target CPU (if not blank)

• The Flasher ATE programs the target CPU

• The Flasher ATE verifies the target CPU

Depending on the settings chosen in the Production tab in the J-Flash tool, this sequence can differ from the one shown above.

Command structure:

#AUTO [module1][, module2][, module3]

Alternatively the modules can be replaced:

• *, will execute the auto command using all modules selected by the latest executed selmodule command.

• all, will execute the auto command using all modules which can be detected.

Results of the Flasher ATE:

Result Meaning

#OK successfully done

if any error occurred during operation. xxx represents the

#ERRxxx

During execution of the #AUTO command, Flasher ATE automatically sends “status” messages via the terminal connection to reflect the state of execution.

error code, normally replied to Flasher ATE PC program. #ERRxxx message may be followed by an additional error text.

Example sequence:

8.3.6.1.2 Command #AUTO NOPATCH

The #AUTO NOPATCH command allows to ignore an existing patch file for the programming.

The background about this is that the 3-wire handshake protocol shall be able to patch data files, too. So the default behavior of the #auto command is that an existing patch file (patch.txt in the module folder) is applied to a data if the #auto command is executed.

Flasher ATE responds with

• #OK if no error occurred

• #ERRxxx if any error occurred during operation. xxx represents the error code, normally replied to Flasher PC program. The #ERRxxx message may be followed by an additional error text.

8.3.6.2 Replies from Flasher ATE

The reply messages from Flasher ATE follow the same data format as commands. Any reply message starts with ASCII start delimiter #, ends with simple carriage return (ASCII code

13) and is sent in uppercase. In contrast to commands, replies can be followed by a de-

scriptive message, which gives more detailed information about the reply. This description is sent in mixed case. The #OK reply, for example, is such a reply. It is followed by a string containing information about the performance time needed for the operations:

#OK (Total 13.993s, Erase 0.483s, Prog 9.183s, Verify 2.514s)

The following reply messages from Flasher ATE are defined:

8.3.6.2.1 #ACK

Flasher replies with #ACK message on reception of any defined command before the command itself is executed.

8.3.6.2.2 #NACK

Flasher replies with #NACK, if an undefined command was received.

8.3.6.2.3 #OK

Flasher replies with #OK, if a command other than #STATUS or #RESULT was executed and ended with no error.

8.3.6.2.4 #OK:<Data>

Flasher replies with #OK:<Len>:<Data> if a #FREAD command was executed. <NumBytes> is the number of bytes which could be read. This value may differ from the number of requested bytes, for example if more bytes than available, were requested. <NumBytes> and <Data> are send in hexadecimal format (for <Data>: two hexadecimal characters per byte).

8.3.6.2.5 #STATUS:<data>

The Flasher ATE replies with its current state.

The following status messages are currently defined:

Message Description

#STATUS:READY

#STATUS:CONNECTING

#STATUS:INITIALIZING

#STATUS:UNLOCKING Unlocking flash sectors.

#STATUS:ERASING

#STATUS:PROGRAMMING

#STATUS:VERIFYING

Flasher is ready to receive a new command.

Flasher initializes connection to target CPU.

Flasher performs self check and internal init.

Flasher is erasing the flash of the target device.

Flasher is programming the flash of the target device.

Flasher verifies the programmed flash contents.

8.3.6.2.6 #RESULT:<Module>:<data>

The Flasher ATE reports the result of an operation on a specific module. If the operation has been completed successfully, it will report the outcome with a single message of this type followed by the last result of the operation.

8.3.6.2.7 #DONE

For the Flasher ATE, getting a result from a module does not necessarily mean, the Flasher ATE is in idle state. Therefore, this message is being sent, once all operations are finished and all modules are back in idle state.

A typical sequence for using the Flasher ATE is as follows:

J-Link / Flasher ATE Mainboard V1 telnet-shell. J-Link / Flasher ATE Mainboard V1 compiled Mar 15 2018 12:28:43 #SELMODULE 1,2 #ACK #SELECTED:1,2 #AUTO * #ACK #RESULT:1:#ERR255:Error while flashing #RESULT:2:#OK (Total 2.653s, Erase 0.327s, Prog 1.960s, Verify 0.234s) #DONE

8.3.6.2.8 #ERRxxx <Data>

If any command other than #STATUS or #RESULT was terminated with an error, Flasher ATE cancels the command and replies with an error message instead of #OK message.

Some error codes may be followed by colon and an additional error text.

For example:

#ERR007:CANCELED.

The error code numbers are described in the following table:

Message Description

#ERR007

#ERR008

#ERR009 Failed to allocate memory. #ERR010 Failed to open file. #ERR011 Failed to read file. #ERR012 Failed to write file. #ERR013 Failed to delete file. #ERR098 Failed to delete file.

input comparators and to control the output logic levels to the target. It is normally fed from Vdd of the target board and must not have a series resistor.

This pin is not connected to Flasher ARM. It is reserved for compatibility with other equipment. Connect to Vdd or leave open in target system.

JTAG Reset. Output from Flasher ARM to the Reset signal of the target JTAG port. Typically connected to nTRST of the target CPU. This pin is normally pulled HIGH on the target to avoid unintentional resets when there is no connection.

JTAG data input of target CPU. It is recommended that this pin is pulled to a defined state on the target board. Typically connected to TDI of target CPU.

JTAG mode set input of target CPU. This pin should be pulled up on the target. Typically connected to TMS of target CPU.

JTAG clock signal to target CPU. It is recommended that this pin is pulled to a defined state of the target board. Typically connected to TCK of target CPU.

Return test clock signal from the target. Some targets must synchronize the JTAG inputs to internal clocks. To assist in meeting this requirement, you can use a returned, and retimed, TCK to dynamically control the TCK rate. Flasher ARM supports adaptive clocking, which waits for TCK changes to be echoed correctly before making further changes. Connect to RTCK if available, otherwise to GND.

JTAG data output from target CPU. Typically connected to TDO of target CPU.

Target CPU reset signal. Typically connected to the RESET pin of the target CPU, which is typically called “nRST”, “nRESET” or “RESET”.

98 CHAPTER 9 Target board design

9.2 Target board design

We strongly advise following the recommendations given by the chip manufacturer. These recommendations are normally in line with the recommendations. Please refer to the the appropriate tables depending on the core:

• Pinout JTAG on page 95

• Pinout SWD on page 96

In case of doubt you should follow the recommendations given by the semiconductor manufacturer.

9.2.1 Pull-up/pull-down resistors

Unless otherwise specified by developer’s manual, pull-ups/pull-downs are recommended to be between 2.2 kOhms and 47 kOhms.

9.2.2 RESET, nTRST

The debug logic is reset independently from the CPU core with nTRST. For the core to operate correctly it is essential that both signals are asserted after power-up.

The advantage of having separate connection to the two reset signals is that it allows the developer performing software debug to setup breakpoints, which are retained by the debug logic even when the core is reset. (For example, at the reset vector address, to allow the code to be single-stepped as soon as it comes out of reset). This can be particularly useful when first trying to bring up a board with a new ASIC.

9.3 Adapters

9.3.1 JTAG Isolator

The JTAG Isolator can be connected between Flasher ATE and JTAG adapter, to provide electrical isolation. This is essential when the development tools are not connected to the same ground as the application. For more information about the JTAG Isolator, please refer to J-Link JTAG Isolator User Manual (UM08010) which can be downloaded from our website.

100 CHAPTER 9 Adapters

Pins 4, 6, 8, 10, 12, 14, 16, 18, 20 are connected to GND.

9.3.2 J-Link Needle Adapter

To connect to the Flasher ATE via programming interface the J-Link Needle Adapter is recommended.

Why to choose the J-Link Needle Adapter:

1. No additional connector required on your PCB

2. Very small footprint

3. High reliability spring pins for secure connections

4. Designed with 3 locating pins, so the adapter can not be connected the wrong way

5. No external power supply required! The J-Link Needle Adapter comes with the option to power the target hardware via J-Link.

These features make the J-Link Needle Adapter the perfect solution for production purposes.

The pinout of the J-Link Needle Adapter is based on the pinout of the needle adapter by TagConnect. Please note, that both pinouts are not identical since the J-Link Needle Adapter comes with a 5V-supply pin.

As you can see on the image below, the three locating pins ensure, that the adapter cannot be connected to the PCB the wrong way.

Moreover, the two “legs” on each side of the connector guarantee a stable and secure contact between pins and the PCB.

The J-Link Needle Adapter can be connected to J-Link via the 20-pin 0.1’’ JTAG to a 10- pin needle connector.

9.3.3 Flasher RX 14-pin Adapter

Flasher ATE itself has a 20-pin JTAG connector mounted but comes with a 14-pin adapter for Renesas RX devices. This adapter also enables Flasher ATE to optionally power the connected target hardware. On the adapter there is a jumper which allows selection between
