In the latest package for ESP32 for Arduino IDE, select Olimex ESP32-GATEWAY, remember to select "Revision F or newer" option and the proper COM port from "Tools". And then use demo from Examples -> Ethernet -> ETH_LAN8720 - it works without problems.

Does anyone have a working code/example for WHATEVER communication over the ethernet modul? So that i would have a basis to continue. Thank you! :)

you can explore alternative operating systems that support the A20-OLinuXino-LIME such as Armbian

For what it's worth it, I'm now running Bookworm from generic debian on Lime2 for over a year and it's rock stable. May not support all olimex nitty gritties on the board but it works for me running a fileserver (1T SSD) on one server, one server with BackupPC and one with Homeassistant.

If you need them for I2C - internal pull up are too weak. Like 30k. Just add external.

Maybe first test via the sysfs before doing it in the DTS, refer to this python package that had internal pull up control:

Dear olimex,

I need to enable internal pullups of A13 on pins

pin 49 (PB17): 1c2b400.i2c (GPIO UNCLAIMED) function i2c2 group PB17
pin 50 (PB18): 1c2b400.i2c (GPIO UNCLAIMED) function i2c2 group PB18

I want to do this with dts, any help is appreciated.

What shloud be added to sun5i-a13-i2c2.dts to achieve the task.



thank you

It is 0.1" spaced. If jumper wire fits in it is 0.1".

But we also sell 0.05" connectors, like here (these are usually used in our Linux boards):
