Gang Programmer Overview and Description

1.2.1Operating the Gang Programmer in PC Mode

In PC mode, the gang programmer is an interactive, menu-driven system that facilitates programming TMS370 family devices and EPROMs. The system al- lows you to perform any or all of the operations listed below.

Program any or all of the 16 devices from PC memory

Modify or add a new device to the device table

Verify any or all devices against either PC memory or the master device.

Upload any of the 16 devices.

Program the 512K master device.

Upload the master device with or without configuration data.

Enter standalone mode.

When you program in PC mode, all LEDs are turned on for a predetermined time as part of an LED test. Then, the software checks whether a device exists in each socket and whether it is properly installed by running a small read-write test. If any device fails, the LED for that device blinks for a few seconds, there are two short audible beeps, and the following error message is displayed:

Device test failed, continue? (y/n)

If you have incorrectly inserted any device(s), you can fix them at this time. If only empty sockets failed, you can continue the programming by pressing . The LED of the failed device(s) remains on during programming. At the end of programming if there is a verification error on any other device, its LED turns on also.

In the PC mode, the push button on the gang programmer is deactivated. The interactive commands for this mode are discussed in Chapter 2 and 3.

The gang programmer's ability to execute any or all of the programmer com- mands on a master device allows you to program a master device for use in standalone mode or to verify programmed devices against the master device or PC memory while in PC mode.

1.2.2Operating the Gang Programmer in Standalone Mode

In standalone mode, the programmer works without the PC interface. You can access the stanalone mode from the PC mode by selecting the standalone command; when the PC is not connected to the Gang Programmer during power-up, standalone mode is automatically selected.

Standalone mode allows you to program and/or verify devices in a production- type mode.

After you install the master 512K EPROM device and any devices you wish to program or verify, the procedure for starting the programmer is quite simple.
