Introduction, Installation, and Setup

Introduction

1.1 Introduction

The MSP-GANG430 is an MSP430 device programmer that can program up
to eight MSP430 flash devices at the same time. The MSP-GANG430
connects to the host PC using a standard RS232 serial connection. The
MSP-GANG430 provides flexible device programming options as described
in Chapter 2.

The MSP-GANG430 is not a gang programmer in the traditional sense; there
are not eight sockets provided to program the target devices. Instead, the
MSP-GANG430 is designed to connect to the target devices in-circuit (i.e., the
target devices are mounted in the customer’s final circuit/system). The
MSP-GANG430 accesses the target devices using connectors to the JTAG
signals.

Chapter 6 contains a schematic that documents how the signals from the
MSP-GANG430 can be brought out to each of the target devices via an
MSP430-standard JTAG connector. The circuit could easily be modified to
connect the signals to the target device pins directly (via a socket) if a
traditional gang programmer was desired.

The MSP–GANG430 is provided with an expansion board that implements the
interconnections between the MSP–GANG430 and multiple target devices.
Eight cables are provided that connect the expansion board to eight target
devices (via a JTAG connector).

1.2 Software Installation

To install the MSP-GANG430 software:

1) Insert the MSP430 CD-ROM into the CD-ROM drive of the computer. The
setup routine automatically opens the default browser of the computer and
displays the MSP430 start page. Alternatively, open the file index.htm
located in the root directory of the CD-ROM using a browser. The MSP430
start page is displayed in the browser window.

2) Select Tool Software

3) Select MSP-GANG430 Gang Programmer

4) Select Save this program to disk under the File Download options and click
OK. A Save As dialog is displayed.

5) Using the Save As dialog, save the GANG430_Rxxx.exe program to the
computer. Make a note of the directory path to this file.

6) Navigate to this file (GANG430_Rxxx.exe) and execute it. A welcome
message is displayed on the screen.

7) The setup program guides you through the installation process. Follow the
setup instructions on the screen.

Software Installation

8) On completion of the setup program execution, the MSP-GANG430
program icons are created in the selected folder. Click on the GANG430
Read Me First icon to obtain important information about the
MSP-GANG430 hardware and software.

9) The appropriate program group and icons are added to the Windows
program manager.

10) To start the MSP-GANG430 software, click the GANG430 icon in the
selected program group (the default program group is ADT430).

1.3 Hardware Installation

To install the MSP-GANG430 hardware:

1) Connect the MSP-GANG430 to the serial port (COM1–COM4 or
extension board) of the PC using the 9-pin SUB-D connector.

2) Connect an external power supply to the MSP-GANG430. The voltage of
the power supply must be between 8 V and 15 V dc and must be capable
of providing a minimum current of 300 mA. The center post of the power
supply connector on the MSP-GANG430 is the positive voltage terminal.

The power supply connection status is indicated by the yellow system LED
on the MSP-GANG430.

3) The expansion board should be attached to the 25-pin SUB-D connector
on the MSP–GANG430. It provides connectivity for up to eight targets, via
the included eight 14-pin cables. The target MSP430 flash devices can be
in standalone sockets or can be on an application’s PCB and are accessed
via the JTAG signals.

Introduction, Installation, and Setup

1-3

Hardware Installation

Note: Maximum Signal Path Length: 60 cm

The maximum length of the signal path between the 25-pin SUB-D connector
on the MSP-GANG430 and a target device is 60 cm.

4) The MSP–GANG430 provides the selected power supply voltage V
(VCC_MSP on pins 7 and 14 of the 25-pin SUB-D target connector; pin
2 on the 14-pin cable) to the target devices in application PCBs. A maxi­mum total current of 150 mA can be provided by the programmer to the
targets.

5) When an external supply voltage V
should also be fed into the sense input pin (MSP_VCC_IN on pin 15 of the
25-pin SUB-D target connector; pin 4 on the 14-pin cable) of the
programmer. This connection allows the integrated level shifters to match
the target JTAG signal levels with the external supply voltage.

When an external supply voltage is used for the target systems, it is very
important to disconnect VCC_MSP from the targets to avoid power supply
conflicts that could potential damage the MSP-GANG430 and the targets.
Connect the external supply voltage to MSP_VCC_IN.

It is not possible to use the MSP-GANG430 with targets powered by the
MSP-GANG430 and with targets powered by an external supply
simultaneously.

2.1.5 Description of the Gang430.ini File

The Gang430.ini file contains the MSP-GANG430 default settings and the last
used GUI settings.

2.1.5.1 Section [System]

The last used settings of the MSP-GANG430 GUI are stored in the
Gang430.ini file before exiting the GUI application program. This information
is stored under the [System] section of the file.

2-6

2.1.5.2 Section [User]

The initial settings for the following parameters are in the [User] section and
may be modified by the user:

CaptionIndexed = 0 (default)
The caption of the MSP-GANG430 GUI in the default state is MSP430 FLASH
Gang Programmer.
When CaptionIndexed = 1, the caption is extended with a suffix [n] to allow
multiinstance operation for programming in automated production
environment that uses caption titles for process control. The suffix n
represents the unique COMn port number for that instance. E.g. for COM3, the
caption is displayed as MSP430 FLASH Gang Programmer [3].

2.1.5.3 Section [Timing]

The [Timing] section shows the approximate time that has elapsed in
milliseconds for various operations of the MSP-GANG430. The parameters
under this section are updated after the associated operations are successful.
The information on the elapsed time is useful for development and setup. The
parameter that is most interesting is the time taken to complete a gang
programming cycle, represented by TimeGangProg under this section.

Programming MSP430 Flash Devices Using the GUI

2.1.5.4 Section [Diagnostic]

The [Diagnostic] section is useful for automatic production using the
MSP-GANG430. During gang programming operation, Busy = 1. After
completion of the operation, the information in the Result group box in the GUI
is also listed in this section for the following: Connected, EraseChecked,
Verified, FuseBlown, OverAll, and MiscErrors, if any. A Busy = 0 terminates
that process and the diagnostics can be read from the .ini file.

For Example:

OverAll=239 (hexadecimal 0xEF) means: All channels except channel 5
were successfully processed (channel 1 represents the LSB, channel 8
represents the MSB of a byte).

Note:

When MiscErrors is nonzero, the diagnostic values are not valid for evalua­tion. Possible values for MiscErrors are shown below.

2.1.6 Target Connector Functional Check

The MSP-GANG430 GUI diagnostics support a functional check of the target
connector pins. The functional check is invoked by selecting the Target
Connector category in the Maintenance group box, and clicking the Execute
button with the appropriate Set Signals defined. The Set Signals value is the
decimal value that represents the combination of the appropriate control bits.
The defined pin’s signal level is available for measurement after execution of
the functional check. The signal levels remain unchanged until another
configuration is set. The target connector functional check must always be
terminated by executing the End of Check setting (0x8000 = 32768) or by
executing an H/W self test to initialize the MSP-GANG430. Table 2–4 shows
the details of the control bits.

Programming MSP430 Flash Devices in Standalone Mode

2.2 Programming MSP430 Flash Devices in Standalone Mode

The MSP-GANG430 supports a standalone mode of programming the target
MSP430 flash devices.

The programming options for the MSP-GANG430 while operating in
standalone mode are configured using the GUI. When the Start button in Main
Process is clicked, all selected options are downloaded into the flash memory
of the MSP-GANG430. Once the download is complete, the MSP-GANG430
can be disconnected from the PC and used standalone to program the target
devices. The START push-button on the MSP-GANG430 operates identical
to the Start button of the GUI. Progress of the operation in standalone mode
is indicated by the flashing yellow LED.

The result status is represented by the rows of green and red LEDs on the
MSP-GANG430. For each channel, a green LED indicates a successful
operation and a red LED indicate a failed operation. If both red and green LEDs
are off for a channel, the target device connected to that channel is not
accessible or is not connected.

In standalone mode, the H/W self test of the MSP-GANG430 can be initiated
by pressing the ST ART key for more than three seconds. The progress of the
test is indicated by alternate flashing of green and red LEDs in groups of four.
Upon completion of the self test, all eight green LEDs are on if the self test
passes. Any other combinations of the LEDs indicate a failed self test.

2.3 Programming MSP430 Flash Devices With User-Configured UART
Handler

The MSP-GANG430 programmer supports programming the MSP430 flash
devices by using generic firmware commands. The generic firmware
commands and protocol are described in Chapter 3.

2.4 Programming the MSP430 Devices With GANG430.DLL

The MSP–GANG430 programmer supports programming the MSP430 flash
devices by using DLL functions. The usage of the DLL functions and their
prototypes (calling conventions) are described in Chapter 4: Dynamic Link
Library GANG430.DLL.

3-1

Commands

3.1 Commands

The MSP-GANG430 can be controlled via firmware commands received on
its RS-232 serial port.

The following firmware commands are supported:

- Load Parameters

- Start

- Transmit Diagnostics

- Erase Image

- Load Image Block

- Load Image Checksum

- Erase Firmware

- Load Firmware Block

- Finalize Firmware

- Select Baud Rate

- Execute Self Test

- Set Signals (at target connector)

- Read Target Selective

- Write Target Selective

- Set Target Vcc

3.2 Firmware Interface Protocol

The MSP-GANG430 supports the following UART communication protocol:

- Baud rates from 9600 to 115200 baud in half duplex mode. The default

baud rate at startup is 1 15200 baud, and is the recommended baud rate.

- One start bit, eight data bits, even parity bit, and one stop bit.

- Software handshake by (not)acknowledge character.

3.3 Synchronization Sequence

To synchronize with the MSP-GANG430, the host serial handler transmits a
SYNC character (80h) to the MSP-GANG430. The MSP-GANG430 acknowl­edges successful reception of the SYNC by responding with a DATA_ACK
character (0x90). If the SYNC is not received correctly , a DAT A_NAK character
(0xA0) is sent back. This sequence is required to establish the communication
channel and/or react immediately to line faults.

Note:

The synchronization character is not part of the data frame described later
in this chapter.

3.4 Data Frame

The data frame format used follows the TI MSP430 serial standard protocol
(SSP) rules extended with a preceding synchronization sequence (SS), as
previously described. The MSP-GANG430 is considered the receiver in
Table 3–1.

3-2

The obvious redundancy of some parameters results from the adaptation of
the SSP, or to save boot ROM space.

3.4.1 Frame Structure

The data frame format of the firmware commands is shown in Table 3–1:

- The first 8 bytes (HDR through LH) are mandatory (xx represents dummy

- Data bytes D1 to Dn are optional.

- Two bytes (CKL and CKH) for checksum are mandatory.

- Acknowledge done by the MSP-GANG430 is mandatory except with the

3.4.2 Checksum

The 16-bit (2 bytes) checksum is calculated over all received/transmitted bytes
B1 … Bn in the data frame except the checksum bytes themselves by XORing
words (2 successive bytes) and inverting the result.

or was executed unsuccessfully.

3.5 Commands—Detailed Description

3.5.1 General

Besides the header byte HDR (0x80) and the command identification CMD,
the frame length bytes L1 and L2 (which must be equal) hold the number of
bytes following L2, excluding the checksum bytes CKL and CKH.

Bytes AL, AH, LL, LH, D1…Dn are command specific. However , the checksum
bytes CKL (low byte) and CKH (high byte) are mandatory.

If the data frame has been received correctly and the command execution was
successful, an acknowledge character DA T A_ACK = 0x90 is sent back by the
MSP-GANG430. Incorrectly received data frames, unsuccessful operations,
commands which are not defined are confirmed with a DATA_NAK = 0xA0.

3.5.2 Load Parameters

The load parameters command is used to download the information the main
process needs for gang programming to the MSP-GANG430. It has to be in­voked prior to the first gang programming command. The parameters are
stored in the system flash memory.

3.5.3 Start

The start command executes the gang programming cycle. The operations
are defined with the load parameters command. The result of the command
execution can be determined using the transmit diagnostic command
described below.

3.5.4 Transmit Diagnostic

The transmit diagnostic command provides the result of the preceding gang
programming command.

Data bytes D1 to D1E hold the parameters as follows:

D1 to D5 give information about success of each target channel. The LSB
represents channel 1, the MSB represents channel 8:

D1 Channels which are connected to the programmer (device detected).
D2 Channels which passed the erase check successfully.
D3 Channels which passed the verification successfully.

D4 Channels which passed the blow fuse successfully, fuse already

blown.

GANG430.DLL Description

4.1 GANG430.DLL Description

The GANG430.dll is used to communicate with the MSP–GANG430 programmer unit and the
connected MSP430 device(s).

The configuration of the MSP–GANG430 should be done with the following sequence:
InitCom // Open communication port
GangEraseImage // Erase image flash memory
GangLoadImage // Write target code into image flash memory
GangLoadParameters // Determine process flow
ReleaseCom // Close communication port

Once the configuration is completed all process specific parameters are stored in the flash memory of
the MSP–GANG430 programmer unit.

The subsequent gang programming process could be done as follows:
InitCom // Open communication port
GangSelectBaudrate // Optional: slow down communication speed

…GangMainProcess // Execute gang programming process
…GangGetResult // Receive result for diagnostic
…GangAccessTargetSFR // Optional: stimulate device pins
…GangProgramTarget // Optional: write serial numbers to targets

ReleaseCom // Close communication port
Several examples showing how the DLL could be used are located in the DLL_Usage_Examples

subdirectory of the GANG430 system. Every function returns an error code listed in the consecutive
paragraph.

This dll could be used separately using the following conventions:

InitCom

long int InitCom(char* lpszComPort, long int lBaudRate)
InitCom initializes (opens) the given communications port, establishes communication with the MSP-

GANG430 hardware, and sets the baud rate of the MSP–GANG430. If successful, the MSP–
GANG430 is reset.

lBaudRate: Valid baud rates are: 9600, 19200, 38400, 57600, and 115200 Baud. The default baud
rate after initialization is 115200 baud.

lpszComPort: The name of the communication port – COM1, COM2, COM3, or COM4
Example:
lFuncReturn = InitCom(“COM1”, 115200);

ReleaseCom

long int ReleaseCom (void)
This function is the counterpart to InitCom. It allows closing a communication with the MSP–

GANG430 hardware.
Example:
IFuncReturn = ReleaseCom();

5.3 Recommendations for Target Connections

The following hardware connections are recommended when connecting the
target MSP430 flash devices to the MSP-GANG430 without usage of the
expansion board:

Recommendations for Target Connections

- The V

pins of all the targets must be tied together and connected to the

CC

positive terminal of the supply.

- The VSS pins of all targets must be tied together and connected to the

GND or negative terminal of the supply.

- For targets without Test/VPP, five interconnections are needed: TMS,

TCK, TDI/VPP, TDO/TDI, and VSS.

- For targets with Test/VPP, six interconnections are needed: TMS, TCK,

TDI, TDO/TDI, VSS, and TEST/VPP.

- Use short cables to connect the target to the MSP-GANG430. Less than

60 cm is recommended.

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

JT AG fuse blow voltage —TDI/VPP or TEST/VPP.

5.4 MSP-GANG430 Target Connector Signals

Figure 5–1, Figure 5–2, and Figure 5–3 show the target connector signals for
the MSP-GANG430. Chapter 5 presents a schematic of the connections
necessary to program multiple target devices.

When an external supply voltage is used for the target systems, it is very
important to disconnect VCC_MSP from the targets to avoid power supply
conflicts that could potential damage the MSP-GANG430 and the targets.
Connect the external supply voltage to MSP_VCC_IN.

It is not possible to use the MSP-GANG430 with targets powered by the
MSP-GANG430 and with targets powered by an external supply
simultaneously.
