ESP32 Forum

I have a dev kit based on esp32-c3 chip. When I try to flash an example the first part of the process completes, but then it gets stuck and never finishes, It doesn't matter if I press boot button or not.
.
I have tried with other esp32-wroom-32 kit and it flashes without a problem. I don't know if the problem resides on the ttyACM0 or some configuration I'm missing. I apreciate any help.

This is probably a hardware issue. It is stuck during the connection to the port (not during putting chip into download mode or flashing). The output of "dmesg" might reveal some information.

You can try to establish a serial communication using any terminal program. Probably you will experience the same issue.

It may help to force the ESP32C3 into download mode by booting with GPIO9 low.
