Could anyone help me? Thanks

    A bit unclear from your post:
    - If you use an example from the SDK unmodified (except for required board file modifications), are you able to flash the device ?

    - If you use CCS, are you then able to flash our device?
    - If you use Uniflash, are you then able to flash our device?

    It's not clear from your response:
    - If you use an example from the SDK unmodified (except for required board file modifications), are you able to flash the device ?
    - If you use CCS, are you then able to flash our device?

    If it fails for both it indicates an a hardware connection error meaning that you have to look closer to your jtag connection.

    OK, so if I understand you correctly everything works out of the box but fails when you try to add a .obj file.

    Could you describe in more detail what the .obj file contain and why you include it with the linker?

    If the inclusion of the .obj file create the issue I would suspect that it tries to change/ use wrong address space or similar.

    solved the problem. i think maybe jtag is lock or something like that. the issue come from missing reset (JTAG)
    could you explain for me why missing reset (JTAG), i can't connect to TI's chip instead of Flash programmer 2 is still detect Ti's chip. Many thank for your support

    The detection of the chi in Flash Programmer 2 only read out one value from the chip. For programming a two way communication is required and as part of this reset is used at the end.
