    Hello,

    Please see the following note in the device data sheet:

    "The default behavior of Get mode is boot-to-flash. On unprogrammed devices, using Get mode will result in repeated watchdog resets, which may prevent proper JTAG connection and device initialization. Use Wait mode or another boot mode for unprogrammed devices."

    What boot mode are you using on your board? Is it possible to switch to the "wait boot mode" for debug purposes?

    Hi Gus,

    Thank you very much for your answer.

    I now have a problem, using JTAG to download the program to tms320f28379d flash, but after the power failure and then power on again, the program is lost, what is the reason,.

    Thanks,

    Hi Zhonghui,

    Some recommendations/tips:

    1. Ensure the MCU power rails are stable during flashing.

    2. Post a copy of your linker command file for review.

    3. Is this happening on more than one board?
