SPI Ethernet Support #5
Description
Hi there,
Love this project! Thanks for creating it :)
Do you have any suggestions for building this for the esp32s3 microcontroller?
I have a LilyGo T-ETH ELite I'm trying to test this on. When I follow the instructions I end up with a bootloop–

I assume this is because it has a esp32s3–

Any thoughts on how to build this for the esp32s3 target?
Thanks!
