TMS320F28379D: Debugging of CLA1

Gerd Seher

Hi,

in last last days I was able to debug the CPA1 (sometimes with problems).
But today I am really not able to to this (including Reboot and Power Off).

I always do:

Start debug
do some debug steps to configure the CLA momories and the pointers to the CLA tasks
Debug window - Connect target to CLA1
"no symbols are defined"
Run - Load - Load symbols
Disassembly window is jumping to 0x000 with no assembler code.
If I go to the code address 0xA000, I can see the assembler code."
But in the Debug window there is still "no symbols are defined" at CLA1 (Suspended)
If I resume, I get:
CPU1_CLA1: Can't Run Target CPU: (Error -2060 @ 0x0) Requested operation cannot be done while device is running. Halt the device, and retry the operation. (Emulation package 9.3.0.00042)

I have CCS 10.2.0.
The CLA1 is running and I can see a GPIO toggeling.
What can I do?

Thanks, Gerd

Did you review some of the previous E2E post on this like this one below:

https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/856414/ccs-tms320f28379d-debug-cla1-in-tms320f28379d

There are few more on the same. Please let us know if this does not address your issue.

Hello Shamim,

this doesn't help.

My problem is, that I am often not able to load the symbols.
(Last time working before one week!)
But this is not a software problem. I am sure, that this is a configuration problem.
After "Load symbols" the state of the CLA1 in the debug window stays "Suspended".

Hi Gerd,

When you load symbols, it does not change the state of the CLA and so it continues to show "suspended" at 0x0. Issuing a run from debug window does not have any effect on CLA as a CLA task can only execute when it has been triggered. Once it has been triggered then the PC will change to the where the triggered task is located.

Here are some debugging suggestions to make sure the CLA task is being triggered - use mdebugstop to have the CLA halt in the task you want to debug.

https://software-dl.ti.com/C2000/docs/cla_software_dev_guide/debugging.html

Here are steps:

1. Rebuild application with mdebugstop

2. Load application on C28

3. Connect to CLA, load symbols

4. Run the C28 core, CLA status in CCS will show running and when CLA task is triggered it should halt at the mdebugstop.

Hope this helps.

Thanks,

Ashwini

Hi Ashwini,

I knew this all (__mdebugstop();) and I did it all, but I cannot load the symbols.
Once last week I was able to debug the CLA1, but not anymore.

Hi Gerd,

Once you load the application on the C28 please make sure you execute the code on C28 past the function where device is initialized. The device initialization enables CLA clocks. Once this is done, then connect to CLA and load symbols.

Do let me know if this helps.

Thanks,

Ashwini

Hi Ashwini,

I did only InitSysCtrl() with InitPeripheralClocks(), CLA_configClaMemory() and CLA_initCpu1Cla1().
But I think, this was too little.
If I start with F8, I can connect with the CLA.

Thanks, Gerd
