[National Technology N32WB031_STB development board evaluation] After clicking PA4, the program cannot be downloaded [Copy link]

I didn't pay attention. I configured PA4 as normal IO. Now I can't download programs. Connecting DAP's RESET doesn't work. Please help me!

Use jlink, and then use the jlink command to erase, and the board only needs to be powered on and off repeatedly.

Now I can’t connect using jlink. As soon as I click on the connection, it will report an error.

No, now I can't connect, it says it can't find the chip. Connect to rest, it also says it's wrong.
