CCS v5, boot.s28 source window misaligned during step, TMS320F28035

I have an issue where the RPC register is set to 0x0000 on returning from TargetBioscfg.

While trying to get to the bottom of this, I am stepping through boot.s28. The alignment of the source window to the actual assembly window is very skewed. And, it gets worse the farther I proceed through the file. It is making it very difficult to use for debug.

See attached screens shots.

Any ideas?

    Jim,

    You seem to be debugging the BIOS 5 boot code and I was able to observe similar behavior as well when stepping through the _c_int00 routine in boot.s28. I believe the reason for the source/disassembly not correlating is either because the BIOS sources were built without debug information or that they were built with optimization which is in turn throwing off the correlation for the debugger.

    I understand that it makes it difficult to debug, but with BIOS5 being in maintenance mode, it is unlikely there will be any changes to address this. I would still suggest that you post a new question to the TI-RTOS forum in case the BIOS experts there can offer additional comments or workarounds for the issue.

    Thanks for your response AartiG.

    I have posted the question to the RTOS forum as you suggested.
