CCS/TMS320F28377S: Loaded .out built for RAM into FLASH, con no longer program FLASH

Part Number: TMS320F28377S
Other Parts Discussed in Thread: UNIFLASH

Tool/software: Code Composer Studio

I have several 28377S-based boards that were mistakenly flash programmed with a .out file that was built for RAM. I can no longer erase the 28377S parts in Uniflash or program in CCS 6.2. I'm using a TI 100v2 jtag adapter. When I connect to the target, without a project, the gel file executes but the memory map displayed in the GEL files tab does not match the memory map specified in the F2837x_Memory_Map() within the gel file. I've inserted a screen shot below. Any suggestions on how to fix this?

    Here's the screen snippet showing the data section of the memory map that does not match the gel file.

    Tom,

    1. What errors do you get when you try to erase using UniFlash/CCS?
    2. Try to set the boot pins to wait mode and then connect/erase.
    3. Regarding the gel file: Check for updates and install if any. If that does not solve it - share your gel file.

    Thanks and regards,

    Hi Vamsi,

    Temporarily setting the boot pins to wait mode and then programming with a valid image worked. Thank you for your suggestion. The actual setup of compiled and linked object files leading to this situation is somewhat esoteric and may not benefit anyone. I regret my simplification of indicating that a file built for RAM and loaded into FLASH caused the problem.

    Thank you,
    Tom

    Tom,

    Glad to know that you are able to erase your devices now.
    I am closing this thread.
