Introduction

CAUTION

When an external power supply is used to power target devices, disconnect V

from the targets to avoid power-supply conflicts that could potentially damage

the MSP Gang Programmer and the target devices.

When target devices are powered from an external power supply, connect the

from the target device to V

extin

(pin 4) on the JTAG, SBW, SWD, or BSL

connectors. The MSP Gang Programmer uses this voltage to detect the

presence of an external power supply.

Set the desired V

level in the MSP Gang Programmer to the same voltage

that powers the target device. This information is mandatory to provide correct

I/O levels for the TMS, TCK, TDI, TDO, and RST signals. If the wrong V

provided, then the I/O levels between the programmer and target devices can

be too low or too high, and communication can be unreliable.

5. The MSP Gang Programmer can be supplied from an external power supply connected to the DC

connector or through a gang splitter (not populated J10 connector). Because the J10 and DC

connectors are connected in parallel, make sure that only one connector provides an external power

supply to the MSP Gang Programmer.

Operation

This chapter describes how to use the MSP Gang Programmer to program target devices. Various modes

of operation, which allow the user to choose the most convenient method of programming, are described.

In addition, this chapter describes the various windows that are used to configure the programming

procedure for a specific target device. The explanations in this chapter assume that the user has properly

installed the MSP Gang Programmer hardware and software as described in Chapter 1.

2.1 Programming MSP Flash Devices Using the MSP Gang Programmer

The MSP Gang Programmer is capable of quickly and reliably programming MSP flash devices using an

RS-232 or USB interface. There are four ways to use the programmer to achieve this task and these

include:

• Interactive

• From Image

• From Script

• Stand Alone

The Interactive mode is selected by default, and is the easiest to get started with, because it requires the

least amount of preparation. After the user has mastered the Interactive mode it can be used to create

images and script files, which can then be used with the From Image and From Script modes,

respectively. Images and scripts are ready-to-go setups than can run with minimal user input. They are

very useful for repetitive programming, for example in a production environment, because they ensure

consistency (because of the re-use of images or scripts, we highly encourage the user to thoroughly test

their images or scripts for correctness before committing them to production). The MSP Gang Programmer

can also be run in Standalone mode to program target devices without a PC. To do this, first create an

image to use for programming, and then save it to internal memory of the MSP Gang Programmer.

Creating images is described in Section 2.1.9.

The following sections describe how to use these modes of operation.

Operation

2.1.1 Programming Using Interactive Mode

Use the following sequence to start the MSP Gang Programmer GUI and program MSP Flash Devices

using the Interactive Mode:

1. Click on the MSP Gang Programmer icon located in the program group that was specified during

installation. Figure 2-1 shows the MSP Gang Programmer GUI in the Interactive Mode (see the Mode

group in the top left corner). This window is used to select the target microcontroller, code file used for

programming, power supply options, communication interface, and more. This window also shows the

result of programming and any errors, if they occur.

2. Select a target device using the MCU Family, then MCU Group, and then desired MCU Type.

3. Select the code file to be programmed into the devices using the Open Code File button or pulldown

menu: File→Open Code File. The formats supported for the code file are TI (.txt) and Intel (.hex) and

Motorola (.s19, .s28, .s37). Code size and checksum appear on the right side (for details on how the

checksum is calculated, see Section 2.1.13).

4. Optionally add another code file to be programmed into the devices using the Append Code File button

(check the box on the left to enable this option). This feature is useful for updating BSL firmware in 5xx

or 6xx MCUs. The two code files are combined together to create one final code file. If a conflict is
