Hello Experts,

I have a problem when trying to connect to the CLA on my new board.

I import the CCS project(cla_asin_dc_cpu01 and cla_asin_dc_cpu02). I choose the FLASH_DEBUG mode。

connect the CLA -->Load symbols(cla_asin_dc_cpu02.out)-->click run -->CCS show “no symbols are defined"。

I am trying to use cla both cpu1 and cpu2, Do you have any demo source?

CCS:8.3.0
Compiler version：TI V20.2.0

SDK: C2000Ware_MotorControl_SDK_3_02_00_00

Thank you very much!

Hi,

Have you loaded the code on the C28x core? The .out needs to be loaded through the C28x code. "Load symbols" is required to just load the symbols to enable debugging in CLA core.

The following document's might be helpful :

yes，I loaded the code of CPU2,please check bwlow:

load CPU2 code(cla_asin_dc_cpu02.out) ->connect the CLA -->Load symbols(cla_asin_dc_cpu02.out)-->click run -->CCS show “no symbols are defined"。

Hi,

Just to confirm, you have clicked run from both CPU and CLA, right?

Have you added break points in the CLA code?

Have you tried the CLA examples from C2000ware?

yes,I can run the CLA in RAM mode.but when i change the FLASH mdoe,CLA doesn't run.

In fact I used the demo sourece：

Hi,

Sorry for the delayed response. I tried loading the same example on my F28379D launchpad, and it seems to load as expected.

After running, it was halted inside a CLATask due to the breakpoint.

This is what I did -> Load CPU1.out in CPU1 ->Load CPU2.out in CPU2 -> Load Symbols CPU2.out in CPU2_CLA -> Run CPU1 -> Run CPU2 -> Run CPU2_CLA

Regards,

Veena
