Description:
I have been trying to get the arduino webserver library or asyncwebserver library working over Ethernet with the built in Ethernet library for a few days now and failing miserably. I am using a w5500 Ethernet chip and it works fine in other projects using udp or tcp messages with no issue, using the exact same hardware setup. The issue arises as soon as i use either webserver library and call the begin function the esp32 crashes and reboots. Ive tried platformio and the arduino ide with the latest core, and 1.0.3 and results are the same.
Ive used the webserver examples for both libraries and both work perfectly fine over wifi, but as soon as i switch it to using Ethernet, crashes happen when begin is called.
I believe the issue stems from the esp32 core and some nonstandard implementations of the server begin function? Despite my attempts i have not been able to figure out how to fix this issue.
Any suggestions on what to try next? Any more information or data i could provide?
The sketch will crash in the same way even without the w5500 hardware attached so that to test and confirm all that is needed is a esp32 dev board. Ive attached one of the webserver examples modified for Ethernet instead of wifi.
Thanks for any assistance!
