PHY JL1101

[whcir911]

How can i get the PHY JL1101 driver added to the ESP32arduino core? The maker of the board i have has provided a driver at this link
"https://github.com/dtlzp/relay_dev_demo/blob/main/esp-idf-dt-patch/components/esp_eth/src/esp_eth_phy_jl1101.c". I'm not sure if this is the correct place to ask this question?

Thanks,
Rick

Hi Rick. This repository is based on IDF. The change will have to be be merged at the IDF level, and then this repository will have to expose the new option.

https://github.com/espressif/esp-idf/tree/master/components/esp_eth/src

This repository is currently on IDF branch 4.4, but will be moving to branch 5.1 soon.

Check with IDF team to see which branch you should PR against.

@whcir911 You can use Tasmota Arduino fork, which has support for PHY JL1101.
Tasmota Arduino esp32 is designed to be used with Platformio.
It is here https://github.com/tasmota/platform-espressif32

I had success by copying the driver from ESPHome project (just removing the outermost #ifdef) into ESP-IDF source tree. (Patch attached.) In my case my interest was to make a DTWonder LAN port work on MicroPython (patch for mpy also attached, FWIW). The pins configuration was also found in an ESPHome config file. Translated to mpy:

lan = network.LAN(mdc=Pin(23), mdio=Pin(18), power=Pin(0), phy_addr=1, phy_type=network.PHY_JL1101, ref_clk=Pin(17), ref_clk_mode=Pin.OUT)

The ESPHome driver is an old driver. Wouldn't use with IDF 5.1. Actual driver espressif/esp-idf#13572

Looks like your driver uses esp_eth_phy_802_3_autonego_ctrl() which appeared in ESP-IDF 5.1.4 and I have to stick with 5.1.2 since MicroPython is compatible with it. Will try again in the future again when mpy accepts a newer version of ESP-IDF.
