SLAU358Q– September 2011 –Revised October 2019

Introduction

The MSP Gang Programmer for the MSP430 and MSP432 microcontrollers can program up to eight of the

same MSP flash or FRAM devices at one time. The MSP Gang Programmer connects to a host PC using

a standard RS-232 or USB connection and provides flexible programming options that allow the user to

fully customize the process. Figure 1-1 shows a top-level view of the MSP Gang Programmer.

The MSP Gang Programmer is not a gang programmer in the traditional sense, in that there are not eight

sockets to program target devices. Instead, the MSP Gang Programmer connects to target devices that

are mounted in the final circuit or system. The MSP Gang Programmer accesses the target devices

through connectors that use JTAG, Serial-Wire Debug (SWD), Spy-Bi-Wire (SBW), or bootloader (BSL)

signals.

The MSP Gang Programmer includes an expansion board, called the Gang Splitter, that connects the

MSP Gang Programmer to multiple target devices. Eight cables connect the Gang Splitter to eight target

devices (through JTAG, SWD, SBW, or BSL connectors). For MSP432 MCUs, an adapter kit (MSP-

GANG-432ADPTR) can convert from 14-pin JTAG connectors to 20-pin Arm connectors.

Chapter 2 describes how to use the MSP Gang Programmer to program target devices. This chapter

describes the modes of operation and how to choose the method of programming. This chapter also

describes the user interface that defines how to program the target device.

Chapter 3 describes firmware commands that give low-level control of the programming process. The

commands correspond to specific actions that the programmer can perform. The MSP Gang Programmer

connects to a host computer through a RS-232 or USB port to receive the commands. Often, you must

use the commands in groups or in a specific order to ensure proper behavior.

Chapter 4 describes Gang430.dll, MSP-GANG.dll, and the functions that are available through them.

Chapter 5 contains an I/O schematic that shows how signals from the MSP Gang Programmer go to each

target device through an MSP-standard JTAG, SWD, SBW, or BSL connector. To make a traditional gang

programmer, you can change the circuit to connect the signals to the target device pins directly through a

socket.

1.1 Software Installation

Use the latest software version, which can be downloaded from the MSP-GANG Production Programmer

tool folder. The MSP-GANG Programmer Software runs on Windows

32 bit or 64 bit: Windows XP,

Windows 7, Windows 8, and Windows 10.

To install MSP Gang Programmer software:

1. Unzip the installation package.

2. Run setup.exe in the root directory of the package.

3. Follow the instructions in the installation process.

4. When the setup program finishes, click the MSP Gang Programmer Read Me First icon to read

important information about the MSP Gang Programmer.

5. The setup program also adds a program group and icons to the Windows desktop.

6. To start the MSP Gang Programmer software, click the icon.

Introduction

1.2 Driver Installation

To install the required drivers:

1. Connect the MSP-GANG programmer to a PC USB port. When the Windows wizard starts, follow the

instructions provided by wizard. When the wizard asks for the USB driver location, browse to the CD-

ROM drive. Drivers are in the main CD-ROM directory location and also in the following directory:

C:\Program Files\Texas Instruments\MSP-GANG\Driver

2. If the RS-232 interface is used for communication with MSP-GANG, the USB driver is not required.

Run the Windows Device Manager to find for the COM port number to use with communication through

RS-232.

1.3 Hardware Installation

To install the MSP Gang Programmer hardware:

1. Attach the expansion board (Gang Splitter) to the 100-pin connector on the MSP Gang Programmer.

The expansion board connects up to eight targets using the included 14-pin cables. The target

MSP430 flash devices can be in stand-alone sockets or can be on an application PCB. The MSP Gang

Programmer can connect to these devices through JTAG, SBW, or BSL signals.

If the target device is an MSP432 MCU, use the adapter kit (MSP-GANG-432ADPTR) to convert from

14-pin JTAG connectors to 20-pin Arm connectors.

2. Connect the MSP Gang Programmer hardware to the computer USB port using a USB A-B cable.

The USB port (5 V, 0.5 A) can supply the programmer.

If the computer does not have a USB port, connect the programmer to a serial port (COM1 to

COM255) using a 9-pin Sub-D connector.

3. If the MSP Gang Programmer is not connected through the USB port, or if the total current

consumption of the programmed target devices exceeds 0.3 A, connect an external power supply to

the programmer.

NOTE: External Power Supply

An external power supply must provide a voltage between 6 V and 10 V DC and must

provide a minimum current of 800 mA. The center post of the power supply connector on the

MSP Gang Programmer is the positive-voltage terminal. The programmer indicates the

status of the power supply connection by using system LEDs and the LCD back light.

NOTE: Maximum Signal Path Length: 50 cm

The maximum length of a signal path between the 14-pin JTAG or SBW connector on the

Gang Splitter and the target device is 50 cm.

4. The MSP Gang Programmer can supply power at a specified voltage V

to each target device (pin 2

on each 14-pin JTAG, SBW, SWD, or BSL cable). The maximum current for each target device is

programmable to 30 mA or 50 mA. If the higher current limit is selected (50 mA) and eight target

devices are connected, then the total current to all devices can reach up to 400 mA. In this case, the

connect an external power supply to the MSP Gang Programmer. The USB cannot supply this current,

because the USB port maximum current is 0.5 A, and the MSP Gang Programmer uses 150 mA,

leaving 350 mA for the target devices.
