Part Number: LP-MSPM0C1104

hi, experts:

I used the board to download and debug, first it works well, then I used a logic analyzer, connect GND and PA11, and try to debug again, then error happens, and I can't download or debug any more, even I reboot the laptop, please help, thanks.

hi, Eason:

I didn't remove any jumper as I used a launch pad as shown above and it seems unnecessary to do so per your ppt, and I tried the 3 methods but failed, can you help to check if I missed anything? Thanks.

What do you mean failed. You fail to do the factory reset or after you do the factory reset the MCU still can't work normally. If the MCU still can't work, I would suggest you to replace it with a new MCU.

I know. But the flow is same. Please ingore "Method 0: Make device enter BSL". Please try Method 1, as this device don't have ROM bootloader.
