Unable to download programs to F28377s

My colleague made a change to the 'Blinky' program and i'm trying to download the default version of 'Blinky' but its stuck on whatever change my colleague made. No matter what demo code I download and debug go to debug mode in ccs6 it doesn't change how the board functions. (The red pin turns on and off depending on how you hold the board.)

1. Could this be some sort of static-caused-damage instead of the program?

2. Am I not actually downloading to the board when I 'build' the project?

3. Is there a way to reset it to 'out-of-the-box' settings?

    Hi Jeremy, what changes were made to program? Following are few things to check.

    - State of XRSn pin on the device. Check if it's continuously toggling.
    - If by mistake security got enable on device due to password values getting program. Check the value @0x78000 to 0x78030 in memory watch window.
    - Also try to erase all flash sectors using CCS flash plug-in GUI.

    Regards,

    I don't know what the changes were.

    State of XRSn pin.
    - From my understanding of the drawings, this should be pins 16 and 56 (Reset#) on the Launchpad board.
    - pins 16 and 56 stay high until i press the reset button. (not continuously toggling.

    Security Enabled
    - In "Memory Browser" There are "FFFF"'s across the board

    Erase all flash sectors
    - I've tried erasing the memory using the "on-Chip Flash" tab > Erase Settings > Entire Flash, Erase Flash. The console says operation completed successfully.

    I don't know if this is related to my current problem but -- a couple other things that have popped up:
    No source available for "0x3ff16a" (28AC0137 MOV @T, #0x0137)
    No source available for "0xc0af" (dissassembly says "0000 ITRAP0")

    Hi,

    If you were able to erase all the sectors of Flash then it should not have any code and you should be able to program it with new code.

    Other warnings you are getting should be ok. Try to re-program the device with new code.

    Regards,

    I was able to download programs apparently. the LED's just never blinked. Perhaps the blue LED is burnt out already.

    I'm currently running simulink models on it.

    Thanks for the help
