Using ESP32 ethernet (WT32-ETH01) with STM32 and OTA

[Gifford47]

Hi!

I want to connect an ESP32 (WT32-ETH01) with a STM32 (black pill).
I currently have an ETH01 board connected to the STM32 (TX, RX, NRST, Boot0) and configured the ETH01 board as follows:

{"NAME":"WT32_ETH01","GPIO":[1,1,1,1,1,1,0,0,1,0,1,1,3840,576,5600,0,0,0,0,5568,0,0,0,0,0,0,0,0,1,1,0,1,1,0,0,1],"FLAG":0,"BASE":1}

I then wanted to configure SHD BOOT0 and SHD Reset like a Shelly Dimmer in the module configuration but then I saw, that gpio 5568,5600 on ESP32 are used for ETH MDC and ETH MDIO instead of SHD BOOT0 and SHD Reset (on normal Tasmota build).
I´ve build a custom firmware to use stm-flasher1.0 for STM OTA feature but this is useless if the pins are not configured for this.

I there a simple way to use an ESP32 with ethernet and a STM32 including OTA feature? Does anyone know what the code change for this could look like?

Don't worry about what pins you use, or which are already in use. You can just config any two usable gpios, as ESP32 does not have locked pins for most functions, only Analog and Ethernet ar tied to certain pins.

Ok, but I haven't a selection/option in the drop-down field to choose SHD Boot0 or reset. I think it's not coded for esp32...

Well, as the Shelly Dimmer is not sold with ESP32, Tasmota does not include this specialized support with ESP32 devices. And if you modify Tasmota to include it (look for where USE_SHELLY_DIMMER is used), it is untested.

Also, the details seem to depend on what STM32 variant you have, meaning that you may have an additional thing there to set up for your variant.

I´ve compiled latest tasmota32 environment with USE_SHELLY_DIMMER and got the following error: tasmota/include/tasmota_compat.h:23:10: fatal error: esp8266toEsp32.h: No such file or directory

How can I include the missing lib?
