I am trying to get the ETH_PHY_demo to work, everything compiles fine and the esp32 starts up, but if a network cable is actually connected, many errors appear on the serial output stating: "emax rx buf err!!" and no dhcp information is received.

I have tried various psu's, network cables, network switches and even different usb cables but it doesn't seem to make a difference.

I setup the esp-idf toolchain following this: https://esp-idf.readthedocs.io/en/latest/get-started/index.html#get-started-get-esp-idf

then setup the config options as per: https://github.com/OLIMEX/ESP32-EVB/blob/master/SOFTWARE/README.md

then setup the config options as per: https://github.com/OLIMEX/ESP32-EVB/blob/master/SOFTWARE/ETH_PHY_demo/README.md

then compiled with make flash.

Serial output:

Nevermind, I managed to get the latest demo thats in the esp-idf repo at: https://github.com/espressif/esp-idf/tree/master/examples/ethernet/ethernet to work without the "rx buf err" appearing when the evb is connected to a network, and an IP Address is requested and received from the network.

Something must have changed in the idf since the olimex examples were written up it seems.

For anyone else that was having the same problem, simply configure the esp-idf ethernet demo found at: https://github.com/espressif/esp-idf/tree/master/examples/ethernet/ethernet but use the make menuconfig options that are on the olimex ESP32-EVB ethernet example page at: https://github.com/OLIMEX/ESP32-EVB/blob/master/SOFTWARE/ETH_PHY_demo/README.md

Now my serial output is as follows:
