TMS320F28379D: How to automatically run a program on CPU2, when debugging on CPU1

Mark Feller

Part Number: TMS320F28379D

Is there a way to automatically run a project on CPU2, when I start debug on CPU1?

I figured out how to load the CPU2 project automatically when the CPU1 project is loaded. However, CPU2 halts at main(), same as normal debug. I see in Debug settings the options for Auto Run, Run to symbol main. However, I would like it to run, and not stop at main.

I've experimented with it a bit, but no success so far.

For example, I've disabled Autorun to main. CPU2 just halts at CodeStartBranch instead. I tried Device_bootCPU2(C1C2_BROM_BOOTMODE_BOOT_FROM_RAM);, and it doesn't get CPU2 going. (and CPU1 remains in a loop in the Device_bootCPU2 function, waiting for C2_BOOTROM_BOOTSTS_SYSTEM_READY)

Thanks!

Found my answer...I modified the GEL file for CPU2 so that it would run automatically after loading.

Sure!

First step is to modify the GEL file used for the second CPU. I added GEL_Run() in the OnRestart and OnFileLoaded routines. Attached is this modified file (for the 28379D).

Second step is to modify the target connection file (ccxml). Open this, go to Subpath_1/C28xx_CPU2 and browse to the modified GEL file:

Last step is to modify the Debug configuration. Under the Program tab, select CPU2 for device, and then browse File System or Workspace for the .out file that you want to be loaded automatically.

Then go under the Target tab and clear the Auto Run check boxes (so it does not stop at main), and select the "Connect to the target on debugger startup" option:

This works for starting debug. I haven't figured out yet how to do this automatically on a reload, such as when you make change while debugging, rebuild, and it asks if you want to download the new program. It's probably an additional change to the GEL file, but I haven't spent much time looking at it.

Anyway, I hope the rest of this helps. It's been a big time saver for me.
