Problem debugging CLA code written in C

Lucas Sinopoli

Hello,

I'm running a basic code written in C for the CLA. The code is an adaptation of the example code provided by TI (atan is the name of the project provided). The code was originally developed for 2806x and I modified it to work with 28035.

There are no errors and the program seems to work fine. However, when I try to debug CCS does not show me the execution of the CLA code. What I'm doing is to connect the CLA, load symbols, and run the program in the CPU to trigger the task. At that point I expect to see the line containing the intrinsic __mdebugstop() pointed and highlighted in green, but that does not happen. CCS gets stuck in showing the same message in red saying "No source available for "0x9000"" and the debug window shows the CLA core suspended and saying 0x00009000 (no symbols are defined for 0x00009000) as if I wouldn't have loaded the symbols.

I'm working with CCS 5.3

Thanks for your help,

Lucas

I have already solve the problem. There was an issue with the memory allocation.

Thanks anyway,

Lucas

I am curious about how you solved this problem. Would you like to provide more details?

Thanks,

It's been a while since I fixed that issue. I believe I wasn't properly copying the memory by executing memcpy(&Cla1funcsRunStart, &Cla1funcsLoadStart, (Uint32)&Cla1funcsLoadSize);

Cheers,

Lucas

Cla program code needs to be copied to certain RAM sector before it can execute.

I wonder whether you have code of this kind at the beginning of CLA initialization:

/* 1. Copy CLA code into the CLA program RAM (for Standalone Flash application) */
memcpy( &Cla1funcsRunStart, &Cla1funcsLoadStart, (Uint32)&Cla1funcsLoadSize );
