TMS320F280049: How to use diagnostic library March13N when LSRAM is allocated to CLA

Part Number: TMS320F280049

Hi Champs,

 

If the Local Shared RAM of F280049 is configured as CLA1 program memory, then the CPU loses the read permission to this part of RAM, so it cannot use the diagnostic library March13N. Is this understanding right? How to solve this problem? Could you please help to give some suggestions? Thanks!

Best Regards,

Julia

    Can you temporarily configure the memory to give the CPU back read/write access while the test runs? The CLA shouldn't be executing while the test runs anyway.

    Even if you were to write a CLA version of the March test that executes from the CLA so the CPU wouldn't need permissions, you still wouldn't be able to run it while the memory is set to program RAM since the CLA can't even read/write from program RAM (it can only fetch).
