GPIO2 on the original ESP32, 46 on the S2/S3 and 8 on the C3/C6 don't stop a normal boot, but held at the wrong level at reset they keep esptool from starting the download mode. The WT32-ETH01 wiring puts TX on GPIO2. Each warning now says what the pin does and what to do: move it for a pin that stops the boot, disconnect it to flash for one that only blocks USB.
