ESP32-C3 USB cdc for initial code upload

Postby AnonTheEngenius » Sun Aug 27, 2023 6:42 pm

Does anyone know if it is possible to use the usb port connected to the usb pins of the esp32-c3 for the first/initial code upload? Or do you have to use serial for that in order to activate the usb cdc upload possibility?

According to the documentation (see picture) here: https://www.espressif.com/sites/default ... eet_en.pdf

i would have guessed that it is possible to use the port for the initial upload based on the joint download boot but i can't seem to get it to work with any configuration of the strapping pins.

That should work just fine, I bootstrapped many an ESP32-C3 that way. Any specific error you're running into?
