TMS320F280049: LSx RAM access fail when DCSM locked

Hi Team,

We met a problem about the DCSM in 28004x.

If DCSM is enabled(Flash Zone 1 and password zone), if we perform the DRV_RAMCHECK(), the code will jump into dead loop(as attached).

If DCSM is unlocked, everything is fine.

This is the CMD file, RAMLSx is allocated for CLA:

Could you please help find a solution?

    HI,

    Have you configured LS0 as secure RAM? If yes then please note that data from LS0 can be accessed from program running from secure RAM only. If code running from unsecure RAM then it'll not be able to access data from LS0. Can you please check the same.

    Regards,
