ESP32 GATEWAY RevE - unable to upload code without C2
« on: January 11, 2019, 07:45:48 PM »
Unfortunately i am not able to upload any code to the RevE boards (RevC work fine).
Esptool.py exits with an error "cannot configure port..."

I think there might be a problem with the 3.3V supply on the RevE boards ?

I noticed that C2 is missing on the RevE board but is present on the ESP32-PoE boards (very similar schematic).

After adding C2 (22µF) to the Gateway RevE boards I am now able to connect and upload and my code works.
