You didn't actually post the problem you are having so it's impossible to say :) I assume esptool fails but it would be helpful if you posted the output. I haven't used an ESP32-C3 but all of the other ESP's don't have USB built in so it depends what USB UART you have on your board - any idea which one it it? -- Daniel O'Connor "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum
