W6100 and ESP32(C3) with ESP-IDF

[nogema]

Hello,

After succeeding to send HTTPS request over WiFi, I am trying to do it over Ethernet. For this I am using the basic ethernet example from ESP-IDF. The problem is the only chip driver available for Wiznet is the W5500 but I am using the W6100. I searched if anyone has already written such a driver but I only found drivers for Arduino ESP32.
So currently I am writing the driver myself from the W5500 driver files (esp_eth_phy_w5500.c, esp_eth_mac_w5500.c, w5500.h) and the W6100 documentation, but no success so far : the RJ45 is well detected but the DHCP never succeeds (timeout endless).

I am using a custom board with the ESP32C3 chip.

Has anyone found or written these driver files ? Or have any ideas ?

Thanks for your help.

Best regards,

Hi,

Can you try this?

Thank you very much ! After fixing a few bugs and updating the code to ESP-IDF V5.0, this works

Hi, would it be possible for you to share your modified code with me, that will be greatly appreciated.

Hello,

I hope these files help you.

I have recently updated, the driver to wiz610, to support ESP-IDF v. 5.3.2
esp_eth_mac_w6100.c
esp_eth_phy_w6100.c
w6100.h
w6100.zip

My only challenge is, that when I close and deinitalize there is a loss of 4,788 bytes. This is because esp_netif_deinit does not release memory...
