TMS320F280049C: LDFU when FLASH memory is secured using DCSM

Part Number: TMS320F280049C


Hi experts.,

We are planning to use DCSM to protect code from unauthorized access and reading. We also have a requirement to LDFU through CAN Kernel. My question is:

1. Can we access (i.e. erase and write) secured FLASH memory from Flash api's to update the firmware?

2. If 1 is not the case, how to address this case? (like how to lock/unlock the secured blocks through CAN commands before we can access secured memory)

Warm Regards,

Mohan
