Hi,
I am porting a program from ESP32-EVB rev.I to ESP32-Gateway rev.G, but it does not work (Ethernet keeps connect/disconnect/connect/disconnect.... I suspect because in the Arduino IDE I set the revision F instead of G.
Rev F is the maximum I can set in the Arduino IDE. Why?
I have
https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
in additional board managers, and I've reinstalled the ESP32 from board manager.

No. I doubt it.

The Ethernet circuit is different between the boards. Different source for the clock and more. My advice is to first test the default Ethernet example of ESP32-GATEWAY if you have trouble follow this document:

It now works, with rev G hardware and Arduino IDE set for rev F.
today I flashed the board with the ethernet cable disconnected. When I connected the cable, it got the IP and everything worked. Now I can reflash and it runs without problems. Go figure.

Cool that it got working.

The changes between revision F and G are minor and should NOT affect any configuration in Arduino IDE, only these two major changes:

- R54 removed. R24 and R16 moved further away from the button.
- Improved EN signal - added C5(1uF/0603) on pin #3 of ESP32. R24 now 10k.
