Hello.

 

I accidentally made this CPU's SWD (PIN 32, 33)
Programmed to I2C0_SCL, I2C0_SDA and written to the flash ROM,

 

DEFAULT: SWD
ALT5: I2C

 

Of course, debug connection with CMSIS-DAP is no longer possible.

As for the question, is there a way to revive this, that is, a writing method to make it the default SWD again?

Someone, please teach. Thank you.

 

P. S.
Sorry, my English is not good
