TMS320F28P650DK: The sysconfig can not assigns CLA program in RAMLS8 and RAMLS9 correctlly.

Hi,

User need to use the CPU address to load and CLA address for run. Did you try running the generated code and saw the issue.

Hi, Vivek.

Yes, I'm sure of that. When I tried using the sysconfig to configurate the CLA, regardless of whether the CLA memory config or the CLA task address regist. The code generated by the sysconfig has this problem. Because the sysconfig generate the configuration code automatically, so the tool does not suggesst developer to modify the code, so I try another way to fix this problem. Firstly, cancel using sysconfig to configure the CLA but manually, before memcpy the CLA task code from FLASH BANK to RAMLS8 and RAMLS9, I give the W/R access of these two RAM from CLA back to CPU(because sysconfig's code run before user's configuration code, at this moment the W/R access is CLA's), then memcpy form LOAD to RUN, otherwise the CPU will not MEMCPY successfully. Indicated in following code segment. But I'd still like to be able to use sysconfig exclusively for all of the device configurations.

Thanks.

Ok, thanks. We'll check this and get back to you.
