MSPM0G1507: Flash Download ERROR:No Cortex-M Device found

Part Number: MSPM0G1507

Hi TI,

I'm having trouble programming the MSPM0G1507 chip. I often get an error "No Cortex-M Device found" during programming. I have one chip mounted on our homemade prototype board, which was successfully programmed and worked properly the first time.

However, after I used the flash erase function in Keil, I failed to program new firmware, and it has never been successful since.

Another chip cannot be programmed with new firmware after the program seems to have crashed. It always says that the chip cannot be found.

Why is this and how can it be solved?

Thank you very much!

    1. Can you check wether the hardware connection is good? Maybe your wire is too long.

    2. I would suggest you to use CCS to try to connect your MSPM0 with launchpad.

    Hi Eason,

    Thank you for the reply.

    1. Yes the connection is good. Perfect. The wire is too long? Emm it's not very long. Just a normal DuPont Line.

    2. Yes, I have already used the CCS and the XDS110 (on the launchpad). It's the same. No one can find the MCU device.

    We are checking our software. Maybe there 's something wrong and cause this issue?

    And we found that maybe the "reset part" has some issues. Power off and on again, the MCU will not automatically run the program. After clicking debugging with the software, it can run normally. Manual reset, MCU will run normally.

    There will be technical support tomorrow. If you have any good suggestions, please feel free to provide them.

    Thank you very much for your reply！

    If it report can't find the MCU. I assume the MCU is not powered or there will be some problem with the MCU setup.

    I think you can get the same result after you remove the MCU and try to debug again. Please check the MCU setup like the power.

    Hi Eason,

    Thank you for your reply.

    昨天Gery和Leo来这边把这个问题解决了。主要还是关于Non Main 的擦除以及Ram地址的原因。目前可以正常烧录了，感谢支持。

    Yesterday, Gery and Leo came over and resolved this issue. It mainly pertains to the erasure of Non Main and the reasons related to the Ram address. Now, normal programming can be performed. Thanks for the support.
