ESP32 Forum

Good afternoon,

I am using an Esp32S3WROOM 1 chip on an Esp32S3-DevKit-C-1 board.
I would like to use the USB connector and the USB/JTAG interface to program the chip instead of the USB/UART connector.

I can see the COM port under ESP-IDF but when run the chip programming,
the programming process does not reach the end. I get the message the chip is not responding :

Could you please help me ???

Does the chip flash correctly if you force it into boot mode (i.e. pull GPIO0 low then reset/power up the chip)? If so, you may need to update esptool.py.
