C2000-GANG

PROGRAMMER FOR C2000

The C2000 Gang Programmer is a C2000 device programmer that can program up to eight identical C2000 devices at the same time. The C2000 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. A top-level view of the C2000 Gang Programmer can be seen in Figure 1-1.

The C2000 Gang Programmer is not a gang programmer in the traditional sense, in that there are not eight sockets provided to program target devices. Instead, the C2000 Gang Programmer is designed to connect to target devices in-circuit (that is, target devices are mounted in the final circuit or system). The C2000 Gang Programmer accesses target devices using connectors that use JTAG signals.

The C2000 Gang Programmer is provided with an expansion board, called the Gang Splitter, that implements the interconnections between the C2000 Gang Programmer and multiple target devices. Eight cables are provided that connect the expansion board to eight target devices (via JTAG connectors).

Chapter 2 describes in detail how to use the C2000 Gang Programmer to program target devices. Various modes of operation are described, and they allow the user to choose the most convenient method of programming. In addition, this chapter describes the various windows that are used to configure the programming procedure for a specific target device.

Chapter 3 describes firmware commands that can be used to control the programming process at fine granularity. Firmware commands can be received over an RS-232 or USB port and correspond to specific actions that the programmer can perform. Take great care in using these commands, because they must often be used in groups for proper behavior, and the order in which they are executed affects the result.

Chapter 5 contains an I/O schematic that shows how signals from the C2000 Gang Programmer can be brought out to each of the target devices via a C2000-standard JTAG connector. The user can easily modify the circuit to connect the signals to the target device pins directly (via a socket) if a traditional gang programmer setup is desired.

This chapter describes how to use the C2000 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 C2000 Gang Programmer hardware and software as described in Chapter 1.

2.1 Programming C2000 Flash Devices Using the C2000 Gang Programmer

The C2000 Gang Programmer is capable of quickly and reliably programming C2000 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

• Standalone

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 C2000 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 C2000 Gang Programmer. Creating images is described in Section 2.1.6.

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