We actually see an USB Device connecting on Port COM of the PC, but the Device is always connecting and disconnecting from the port, so we don't have time to program it. Pulling IO9 down doesn't chan...

We see an USB device connecting to the computer, but this device is not recognized by the PC, so we can't do anything with this connection.

We tried to blow the fuse with the serial flasher and also to use the internal USB/JTAG peripheral on GPIO18/19, but both of these solution don't work and it seems like the device doesn't connect : espefuse.py -p COM7 burn_efuse JTAG_SEL_ENABLE Connecting........_____....._____....._____....._____.....

Thank you for your help.

How do I use the serial flasher to blow the fuse in question ? I didn't find that in the datasheet...

Hello, We currently have issues with the programmation of ESP32C3MINI1-H4. We produced 12 PCB with this module on it and don't succeeded in reprogramming them on our PCB with JTAG protocol. We have also Development boards (ESP32-DEVKITM-1) of this module, and the JTAG programmation works well on it....
