Using CCS6, I have the linker cmd file setup as can be seen here

and I have low level init assembly file:

I have the CCS6 "Allow Read/Write/Erase access to BSL memory" checked.

Then when I go to debug the system, the memory locations cannot be seen:

Then when I look into the BSLSIG area starting at 0x17F0, it looks empty, why?

Probably you must unlock BSL by your code. Don't remember right now if locked BSL will return 0000 or FFFF value. Maybe it is erased.

OK that worked, just had to change the low level init assembly file line #87 from BIC to BIS to un protect.

Except that I think just bricked my first uC. When loading the program I get this:

Does it make sense?

Actually that was not the case.

The previous issue was due to linker cmd issue, but the BSL memory just started to show up even when I went back to the old code. Wish I knew why.
