3 years ago RMII clock output mode is not always work on esp32, we have two GPIO (16 and 17, they're inverted), in my experience, if GPIO17 can't work, then GPIO16 could work. Many causes can lead to such issues, like PCB trace (remember RMII clock is 50MHz) length. I can't reproduce your issue with my LAN8720 breakout board and some wire jumpers. Maybe you should go to the forum to ask for help.

3 years ago we're seeing a similar issue with a custom board + LAN8710, the MAC comes up, connect / disconnect events work, and data is received / transmitted, but, we never receive an IP.
setting the debug level to VERBOSE shows incoming ICMP packets that appear to be corrupt (MAC addresses that do not exist on the network etc.) so we're working on the basis this is an RMII / clock signal integrity issue. do y'all have any advice for further diagnosing this?

3 years ago Hello,
Regarding the above issue, I was able to get the static IP address using the Arduino ethernet example. I used the below command to assign my static IP. ETH.begin();
ETH.config(IPAddress(192, 168, 1, 101),IPAddress(192, 168, 1, 1),IPAddress(255, 255, 255, 0),IPAddress(192, 168, 1, 1), IPAddress(192, 168, 1, 1));
Output: image
My question is, I want to disable the DHCP and want to assign the static IP above the same way in the esp-idf example. Where should I change in the esp-idf ethernet basic example program?
Thank you

To set static IP address, firstly you need to stop the dhcpc by esp_netif_dhcpc_stop, then set IP into by esp_netif_set_ip_info
More info, please refer to https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/network/esp_netif.html

3 years ago The above problem has solved. Thank you all for your support.
Hello,
I am currently using ESP32-POE board and tried to build an Ethernet Connection. Following is the result.
Below is the example configuration& ethernet configuration
Thank you
