Burned or Bricked raspberry 4b - no 3.3v
Hi, im setting up my custom printer and i want to use RatOS for idex mode. Setup:
Kraken v1.0
rpi 4b / 3b+
2x ebb42
orginal vaoc camera ect
Problem is that everything was working ok, i configure printer mostly and nearly everything was working.
I plugged VAOC camera to USB HAT, nothing happen so i click button "Reboot" under Host Control.
After that i loose 3.3v on the pi (green status LED, also checked with multimeter on the GPIO, 5v is there)
With 3b+ 1gb ram everything work fine afther that.
And now i have 3 bricked raspberry pi 4.
Before that last situation that is above i've had also problem with GND connections on RPI (some potential beetwen USB C on RPI and USB C plug, power form dedicated power suplly, so i cut the cable and take the GND to GND of the machine to be sure its ok, and after that, that problem go away so i take another pi to test it).
But problem don't go away, and third one bricked.
Need help. Same OS from microSD goes again on the 3B+ so i can provide any logs.
I think it can be weird problem with power delivery on rpi 4b, i dont belive is electrical problem because 3b+ works fine but has only 1GB ram so not to much for what i need.
Also standard Rapsberry pi OS won't boot so the raspbbery pi is bricked somehow but i don't know what is wrong.
