Hi,

We Observed the following memory security error while loading boot loader for TMS470R1B1M Processor in some of the boards

Do you have security keys to unlock the memory or any other suggestions for this?

Jayadeep,
I am not familiar with this tool, so I cannot comment on its usage.
However, the SM470R1B1M uses an MSM for memory security.
When blank, the keys are all FF. Access to the proper password locations unlocks the memory.
If the keys have been programmed, then only accessing with correct keys will unlock the memory.
See spnu243 for MSM usage.
