CCS/TMS320F28388D: Can't Load CLA Application into Target device - Data Verification error

Hi Amulrass,

Are the C2000ware examples also failing with data verification error? Can you confirm it?

Have you made any changes to the linker command when trying out between F2837x Vs F2838x devices? Note that the memory map is slightly different across the two and it might cause this error. Please check the Memory map(Section 6.3) in the respective device datasheets

Hi,

Yes, the C2000ware examples are also failing with data verification error. The screenshot in my previous query is actually C2000ware example only 'cla_ex1_asin'. Yes, I updated linker command file for F2838x.

Amulrass,

Are you trying to "Load program" to the CLA core? You should only perform Load symbols on the CLA core.

Please refer to the debugging section in the CLA FAQ page: https://software-dl.ti.com/C2000/docs/cla_software_dev_guide/

Hello Praveen,

I tried to load symbols also for CLA on TMS320F28388D. This time it doesn't throw any data verification error but there is no effect of the symbols loading. The CLA is not all running and it is not showing any function frames at all. I could see only the main CPU1 variables updating. So, both Program as well as Symbol loading fails for CLA.

If i do the same "Load program" option for CLA on TMS320F28379D hardware, the both the program and symbols are loaded successfully and I was able to debug without any issues. Attached is the screenshot for TMS320F28379D board.

I would like to ask for an Online debug session through Webex or Skype meeting to resolve the issue on tommorow. Can anyone support?

Best Regards

Hi Amulrass,

The CLA core will have the PC pointing to 0x00000000 before starting a task from C28 side and hence it might look like there is no effect because of 'Load symbols'. Once the task is started from the C28x side, you should be see the CLA core moving ahead. It may or may not be visible to naked eye based on the size of the cla task. Hence I would suggest you to place breakpoints inside the cla tasks and observe if the breakpoint is getting hit.

"Load Program" is not a recommended way to debug the CLA core.

I am attaching CLA debugging training video link below. Please go through it and let us know if you have more questions

Hi Amulrass,

Taking a closer look at your ccxml, have you changed something here? Because I see only one C28x core(&CLA) in the snapshot. Can you create a new ccxml and try again?
