ESP32-C3 No serial communication on native USB

Postby Niklas Sommer » Fri Nov 04, 2022 3:58 pm

Hello, I have a custom board that is using the esp32-c3 connected via the built in USB interface and flashing/running code works fine but printing data via serial does not work. Any ideas?

Do you have a bit more information? SDK, version, how did you configure it, ...?
