minichlink bricked my Ch32x033! #446

Hello My ch32x033 was working fine, until I decided to enable the NRST by using the command ./minichlink -d Now, my chip is bricked, and I can't un brick it even after using the command ./minichlink -u Any help would be very much appreciated! TIA

How are you connecting the power to the chip/programmer? For unbrick to work, it must be powered off the 3.3v rail of the programmer.

Rockwell1799 commented 1 hour ago

my connection is as follow: Mcu ---> programmer VCC ---> 3.3V GND---> GND CLK (PIN C19) ---> SWC DIO (PIN C18) ---> SWD

I can test tonight in case no one else gets a chance before then.
