DOES 3.3v and gnd short circuit brick stm32 ?

Kishan Joshi

I have custom board with minimal design only stm32 chip is there and couple necessary capacitors and due to some soldering issue, i got shorted with 3.3 and gnd .. accidentaly i powered it on and for debuging it was connected like this for 2 minutes. now stm32 is not communicating through swd. Did it brick stm32 by shorting 3.3 and gnd for a minute ?

Can you please elaborate ? I have updated the image with newer pcb and solder paste is attached just ready to solder after i have a confirmation that orientation is correct. Waiting for your confirmation

Thank you sir!!!​

This orientation is now correct.

> Can you please elaborate ?

What I meant was I don't know how to interpret "oh ok so my dot has to be straight instead of the text right ?"

How can a dot be straight and text be right? How can you make a dot not straight? Maybe there is a second language problem at play here.

In any case, orientation is now correct based on the position of the crystal.
