After normal power-on, the MCU does not run, but as long as something is used to shield it, it will return to normal. Help to see what is the reaso

Hi @leo12345678 ,
Try to remove R13, pull-up resistor on reset pin, it is not required. we have one internally.
Hope it helps.

We remove the R13 and it still didn't work, but we blew it with a fan for a while and it came back to normal, so what's going on here? Thank you very much!

crystal oscillator not starting?
is this board your own design, or purchased from some supplier?
if the latter, is it your own firmware? Do you have any known-good reference firmware?
