ESP Flash didnt work well

Hey Guys tried to flash the ESP ( from the link in the github AZ-delivery esp32)

ESP unplugged / just usb not connected to board… idk if this is important
but after a successfull flash i got only errors in the serial console +
see pic…

You have to connect ESP to IC.

These are normal warnings / errors as the code is looking for the expected IO expanders and not finding them. If you plug the ESP32 into the controller PCB it should work as expected.
