Help: A fatal error occurred: No serial data received.
-
Hi - I'm new around here, so hello everryone.
I have been getting this error every few times I try to upload and must reconnect the Cardputer (disconnect, press G0 etc.) to get it working again. It happens maybe every 3rd time I want to upload and not only is it becoming very tedious, but I'm worried that it's eventually going to wear out the USB socket.
Does anyone know the solution to this and/or why this happens? I'm using Mac, Arduino IDE 2.3.3. All my libraries are up to date. As I said, it works 2/3 of the time then this happens.
Tried to search - there was a similar query but nobody answered it.

Generally, No serial data received is because the ESP32 has not entered download mode successfully.
