options.

With Erase Flash Memory is erased before programming (only with flash devices).

The following options are possible:

− Main and information memory

− Main memory only With Erase Check Erase check is performed before programming operation is executed. With Verify Each section is verified after it is programmed, or an error message is

displayed if verification fails.

With Blow Fuse The code-protection fuse is blown after the entire object code, with verify, is

programmed. This action is irreversible and disables future on-chip memory access (reading or programming). This step is not performed if verify is disabled or verify fails. A warning is displayed.

Erase operation can be done only with flash devices, according to the selected option.

By file Only the memory locations corresponding to the selected object file are

erased. All other memory locations keep their old data (smart erase). By device The entire flash memory of the device is erased. By range An erase is performed depending on the values entered in the range fields.

Checks if memory locations are erased. By file Checks only the memory locations used by the selected object file. By device Checks the entire programmable memory of the device. (No RAM is

checked.) By range An erase check is performed according to the range of memory locations in

the range for Erase Check/Readout field.

Note 1: For some MSP430 family members, e.g., MSP430F2xxx devices, portions of flash information memory are factory preprogrammed with calibration data. Depending on which method is used for erasing the flash memory, this calibration data may be erased. Should the calibration data be conserved, it must be read out prior to the information memory erase or a flash erase method that does not affect the calibration data memory locations must be used. See the respective device data sheet for further information on preprogrammed calibration data memory locations.

If it should be saved, the following erase options must not be used as the Info memory will be entirely erased:

− Program with Erase Flash (flash-erase options: Main and Info Memory) or

− Erase Flash by Device

Instead, Erase Flash by File or by Range should be used.

2.2.4 Content of PRGS430.ini File

The last settings of the PRGS430 graphical user interface (GUI) are stored in the .ini file before exiting the program. This information is stored under the Program Device System section.

Additionally, the following parameters are in the [Options] section and may be modified:

[Options] \BlowFuse = 1 → The blow fuse button in the GUI is disabled to prevent

accidental blow of the irreversible fuse. LastResult = 0 → If the program is called with command-line parameter, the

error code which is returned to the system when exiting the program is also stored here.

2.2.5 Use of a [Project].ini File

Some default options could be changed within a [Project].ini file. This file has to be in the same directory as the object code file. The following variables could be defined or redefined there.

Content of PRGS430.ini File

The name of the file should have the same name as the object file with the extension .ini.

[ProgramDevice] UserMemProtect = Start, Size UserMemProtect2 = Start, Size UserMemProtect3 = Start, Size UserMemProtectn = Start, Size DisableTIMemProtect = 0

Memory ranges defined in the UserMemProtect and UserMemProtect [n] option are read out and reprogrammed after erase (flash device only). [n] could be a number ≥2 and be in ascending order.

If a memory protection is activated in the device definition file from Texas Instruments, it could be switched off with the DisableTIMemProtect = 1 option.

Operation

2-9

Command Line Options

/SVolt:x.x

2.3 Command Line Options

2.3.1 General Definitions

0: Off 1: First selectable option 1: On 2: Second selectable option

3: Third selectable option

The PRGS430.ini file options are used if they are not specified in the command line. The command line option overwrites the .ini file options.

The program exits automatically if a command is passed via the command line and the command was executed. There is only a small status window opened during the execution.

Only one command identifier (/cmd:) is allowed within the command line. Otherwise, the execution is canceled and an error is returned.

If an error in the command line parameter is detected, the program exits with an error message.

The filename may also contain a path. If special characters are used, the string has to be inside quotes (for example, \\server\adt430\PRG files\test.txt). If an error is detected within the filename, the operation is canceled and an error is returned.

2.4 PRGS430.DLL—Description

The PRGS430.dll is used to communicate with the MSP−PRGS430 hardware and the connected MSP430 device.

The initialization of the PRGS430 should be done with the following sequence: InitCom

SetDeviceType SetV

. InitTarget

. ...

. ReleaseTarget ReleaseCom

Several examples showing how the DLL could be used are located in the “DLL_Usage_Examples” subdirectory of the PRGS430 system.

This dll could be used separately using the following conventions:

/FN0001/ InitCom

long int InitCom(char* lpszComPort, long int lBaudRate)

PRGS430.DLL—Description

InitCom initializes (opens) the given communications port, establishes communication with the PRGS430 hardware, and sets the baud rate of the MSP−PRGS430. If successful, the MSP−PRGS430 is reset and V

is set to

0.0 V (the voltage should be set after the first user action to validate the correct value).

lBaudRate: valid baud rates are: 9600, 19200, 38400, 56800, and 115200 baud. The default baud rate after installation is 115200 baud.

lpszComPort: the name of the communication port—COM1, COM2, COM3, or COM4.

Example: lFuncReturn = InitCom(”COM1” 115200)

/FN0002/ ReleaseCom

long int ReleaseCom (void) This new function is the counterpart to InitCom. It allows to close a

communication with the MSP-PRGS430 hardware.

is set to 0 and all outputs are set to the Hi-Z state.

Example: IFuncReturn = ReleaseComm()

/FN0003/ SetDeviceType

Example:

lFuncReturn = SetDeviceType(char* lpszDeviceName)

Selects the device type. lpszDeviceName: name of the device in file device.cfg Example: lFuncReturn = SetDeviceType(”MSP430F1121”)

Operation

2-13

PRGS430.DLL—Description

/FN0004/ InitTarget

long int InitTarget(char* lpszDeviceName) Initializes the JTAG access to the target device, detects the device type, and

reports when the detected device does not match the parameter DeviceName passed.

lpszDeviceName: name of the device in file device.cfg Example: lFuncReturn = InitTarget (”MSP430F1121”)

/FN0005/ ReleaseTarget

long int ReleaseTarget(void) This function performs a PUC and releases the JTAG access to the target

device. All JTAG signals from the serial programming adapter are switched to Hi-Z. The device starts program execution if it is still connected to V

Example: lFuncReturn = ReleaseTarget()

/FN0006/ Erase

long int Erase(long int wStart, long int wLength, long int Flags) This function erases flash memory (if available). The protection of areas can

be disabled by setting the DISABLE_TI_MEM_PROTECT−Bit in Flags. wStart: start address of the area to be erased. Allowed values :

0x0000−0xFFFE (see memory map of the corresponding device) wLength: length of the area. Allowed values : 0x0000−0xFFFE (see the

memory map of the corresponding device) If erasing information and main memory segments, first erase the information

memory segments, then erase the main memory segments. The mass erase sequence then would be: Erase(InfoStart,InfoLength,0);

Erase(MainStart,MainLength,0); The function invokes a mass erase for information or main memory if the start

address and the complete memory range of the information or main memory is specified. If the range specified is not complete for that device, a segment erase of the individual segments is performed.

Flags DISABLE_TI_MEM_PROTECT (0x01)

If this bit is set, the memory protection settings in device.cfg are ignored. Example:

lFuncReturn = Erase(long:0xF000, long:0x1000, long:1)

2-14

PRGS430.DLL—Description

Note: For some MSP430 family members, e.g., MSP430F2xxx devices, portions of flash information memory are factory preprogrammed with calibration data. Depending on which method is used for erasing the flash memory, this calibration data may be erased. Should the calibration data be conserved, it must be read out prior to the information memory erase or a flash erase method that does not affect the calibration data memory locations must be used. See the respective device data sheet for further information on preprogrammed calibration data memory locations.

/FN0007/ EraseFile

long int EraseFile(char* lpszFileName, long int iFileType, long int Flags, char* lpszProjectIni)

EraseFile() erases all addresses used in the specified file. iFileType: FILETYPE_AUTO (0x00) − Autodetection of file type (Intel-hex or

TI-TXT) FILETYPE_TI_TXT (0x01) − File type is TI-TXT FILETYPE_INTEL_HEX(0x02) − File type is Intel-hex Flags: DISABLE_TI_MEM_PROTECT (0x01) If this bit is set, the memory protection setting device.cfg is ignored. lpszProjectIni: name of the {project}.ini file, if protection settings from this file

shall be used. If there is no protection, replace lpszProjectIni with NULL. Example:

lFuncReturn = EraseFile(”text.txt”, long:0, long:0,

PRGS430.DLL—Description

Note: Use PGM_ERASE_INFO only together with the PGM_WITH_ERASE flag.

lpszProjectIni Name of the {project}.ini file, if protection settings from this file are used. If no

protection is required, replace lpszProjectIni with NULL. The added features do not need to be used—for ProgramFile according to

older specification, just call ProgramFile(FileName, FileType, 0, NULL); if no {project}.ini file or erase check is used, just call:

Example: lFuncReturn = ProgramFile(FileName, 0, 0, NULL); // with autodetect file type

Note: If an erase or erase-check function reports an error, the function ProgramFile() is aborted before programming is started.

3.2 Basic Hints

Dimensions

150 mm (W) × 30 mm (H) × 95 mm (D)

These basic hints are useful for programming MSP430 devices or MSP430 devices on printed-wire boards (PWB).

- All V

pins of an MSP430 device are tied together and connected to the

most positive terminal of the supply.

- All V

pins of an MSP430 device are tied together and connected to the

most negative terminal of the supply.

- The interface should supply the MSP430 with proper conditions according

to the device data sheet, in terms of current, voltage levels, and timing conditions.

- Make sure the proper signal connections (see Section 3.3) are made.

- Short cables to interconnect the interface to the MSP430 device or PWB;

less than 20 cm is recommended.

- Ensure low-impedance interconnections − especially for the path of the

programming and fuse blow voltage.

- When a device with a transparent window (MSP430E3xx family) is

programmed, the window should be already covered with an opaque label while the device is programmed. Since ambient light contains the correct wavelength for erasure, keep the transparent window covered after the device is programmed.

(depending on device)

Voltage source is used with MSP430 devices or PWBs. The voltage level is set by software.

Signal used to select pin or JTAG function or to apply VPP

The output signal levels of the programming adapter are near GND or VCC_MSP.

- The RST/NMI terminal of the device must be high; otherwise, the access

to the device via JTAG system may fail.

- The programming procedure (handling of the SW) is described in

Chapters 1 and 2 of this manual.

- The connections from the MSP430 terminals must follow EMI rules, such

as short lines and ground planes. If TMS line receives one negative pulse by EMI strike, the fuse current is activated (with fuse version 1.0). The fuse current flows from TDI(/VPP) pin to GND (or VSS).

The RST/NMI terminal on the MSP430 device has to be held high by an external resistor during access of the device through JTAG. In a noisy environment, consider using an additional capacitor from RST

/NMI to VSS.

Note:

The example schematic shows a system where the target voltage is supplied by the MSP−PRGS430. For in-system programming with an external supply voltage, do not connect pin 2 of the JTAG connector. In this case, the supply voltage setting in the PRGS430 must be adjusted to the external supply voltage level. The TEST/VPP connection is only required on lower pin-count devices with multiplexed JTAG pins.

3.7 Interconnection of MSP−PRGS430 to Flash-Based MSP430 Devices

The circuit diagram in Figure 3−5 shows the connections required to program flash-based MSP430 devices (MSP430Fxxx) with the MSP−PRGS430 programming adapter. Consult the device data sheet for the specific device location of the power supply and JTAG pins. Ensure that all positive and negative power supply pins are connected together.

The signal TEST/VPP is only required on lower pin-count devices with multiplexed JTAG pins. In this case, special attention must be given to the circuit design around the four JTAG pins (TDO/TDI, TDI, TMS, and TCK), since they are shared between the applications hardware and the JTAG interface used by programming adapter.

Intel-Hex Object Format

A.1 Intel-Hex Object Format

The Intel-hex object format supports 16-bit addresses and consists of a nine-character (four field) prefix that defines the start of record, byte count, load address, record type, and a two character sumcheck suffix.

The two record types, which are represented in the nine-character prefix, are described below:

00 = Data record (begins with the colon start character) 01 = End-of-file record

Record type 00, the data record, begins with the colon (:) start character and is followed by the byte count, the address of the first data byte, the record type (00), and the sumcheck. The sumcheck is the 2s complement (in binary) of the preceding bytes in the record, including the byte count, address, and data bytes.

Record type 01, the end-of-file record, also begins with the colon (:) start character. The colon is followed by the byte count, address, record type (01), and sumcheck.
