c6713 shorted power and ground

Hello,

I'm working on a project using the c6713 dsk

i attempted to add an extra peripheral power connection (5V EPI pin 6) while the board was powered.  (not my brightest idea)

using some stranded wire, i believe i shorted power and ground pins for a moment...  

...everything stopped working and the led's no longer run their typical startup routine out of reset.

with power applied, i'm still getting 5v from the appropriate EPI pins, but I cant get code to run, and the core feels hotter than it should.

Am I completely out of luck with this board, or is there any hope of troubleshooting?

thanks for any responses!

Mac

    Mac,

    If you have removed everything that you tried to add, so you only have just the unmodified DSK6713, you should be able to get it to work after power cycling it unless it has been permanently damaged. For power cycling, be sure to unplug the power from the board and also unplug the USB or emulation cable from the board to make sure no power sources remain.

    For troubleshooting, this is the same problem as validating a new board design, or the board bringup process. You can search this forum and the TI Wiki Pages for advice on that type of debug.

    Look at power supplies to make sure they are at the right levels.

    Look at clocks and reset to make sure they are working right, and timed correctly relative to the power supplies.

    Hope this helps some.

    Regards,

    Mac,

    Can you able to connect the board using emulator via CCS when powered ON.
    Whether you were not connect the target or run the application project using CCS.
    Refer the below wiki page for how connect the C6713DSK board,

    Thanks for the response,

    I have been capable of running projects on the board via the emulator up until the incident occurred.

    Now, I am able to connect to the debugger, but I never reach main(). 

    Instead, it appears that the board is stuck in the reset interrupt vector (_c_int00)

    I have not been successful getting the board to reset properly let along getting my program to execute.

    thanks,

    Mac

    Mac,

    I can suggest, build the project before that remove the debug folder.
    Once the build complete and try to load the image through emulator.
    Check now is it coming to main?
    If it is not happening, I am wondering fault in memory portion of the hardware.
    Please move this thread to hardware.
