Hi,

Using custom board, Processor 28335, XDS100 V1 USB, CCS 4

Getting following error during connection.

Error 0x00001200/ 1135

Error during OCS, Target

Unrecoverable emulator error.

--------------------------------

This started happening after

I loaded the program in flash with debug option from IDE. It was not put in run mode.

DSP Power was turned off. After power on I am getting this error.

Tried with full power off and restart computer as well as DSP board couple of times.

How to get out of this situation.

Thanks,

Deepak

    Hi,

    Reading other posts.

    I setup the processor to bootrom wait mode.

    gpio84 -> 1

    gpio85 -> 1

    gpio86 -> 0

    gpio87 -> 0

    When I connect and try to go to debug mode I get this error.

    C28xx: File Loader: Data verification failed at address 0x00008000 Please verify target memory and memory map.
    Error found during data verification.
    Ensure the linker command file matches the memory map.

    When I compile the project for flash operation. I get following error.

    C28xx: Flash Programmer: Error erasing flash memory. Device is locked or not connected. Operation cancelled
    C28xx: Flash Programmer: Error erasing Flash memory.
    C28xx: Flash Programmer: Device is locked or not connected. Operation cancelled.
    C28xx: Trouble Writing Memory Block at 0x338e06 on Page 0 of Length 0x16
    Cannot write to target

    When bootrom "wait" mode not set I egt following error

    Error connecting to the target:
    Error 0x80000200/-1041
    Fatal Error during: OCS,
    Device driver: Problem with the Emulation Controller.
    It is recommended to RESET EMULATOR.  This will disconnect each
    target from the emulator.  The targets should then be power cycled
    or hard reset followed by an emureset and reconnect to each target.

    Same code/out file is working on second board.

    TIA,

    Deepak.
