Hi,

Thanks a lot for your answer, i soldered 0.1uf capacitor (don't have 1uf) with no result. Still nothing in serial.

Hello,

I made a custom PCB with a ESP32-ROOM-32 and after a few cycle of use, my PCB won't start anymore. Five of my ten mountig are not working anymore with the same symptom. The power supply is OK, but when i plug a serial programmer there is nothing on the output.
It seem the ESP32 don't start ...
