TMS320F280025: How to Unlock RAM When Locked and Verify Through SCI

Part Number: TMS320F280025
Other Parts Discussed in Thread: C2000WARE,

Tool/software:

Dear TI Expert:

We use a self-developed update tool to download the "flash_kernel" from C2000Ware through the SCI interface for programming Flash memory and OTP. And the programming process completes successfully.
However, the issue we encounter is that when the RAM is locked, it causes the download of the flash_kernel to fail.
Therefore, we would like to know if it is still possible to perform a verify check on the flash memory when the RAM is locked,
provided that we have the CSM password.
