Trying to flash my first hello_world example to an ESP32-C6 DEVKITC-1 V1.2 using ESP-IDF extension on VSCode a dialog box pos up with "OpenOCD is not running, do you want to launch it?". Pressing Yes results in

OpenOCD Exit with non-zero error code 1

[Stopped] : OpenOCD Server

Can't perform JTag flash, because OpenOCD server is not running!





I of course read all the FAQ but I don't understand them, so that I appreciate any concrete hint how to fix this.

I believe this is because you have selected JTAG, when you should select UART in ESP-IDF/VSC.

Thanks @klaatu2. Changing to UART really helped to enable flashing via UART. But my issue was that I simply used the wrong USB connector. Switching the cable to the other one I am now able to flash via JTAG and also debug.
