Hello, I am using a "J-Trace Pro for ARM Cortex-M processors" debugger for a JTAG connection to my ESP32-S3-DevKitC-1 board. I am able to flash the board over USB/serial, however am unable to use the JTAG interface through the GPIO pins. I have read that an eFuse or two may need to be burned in orde...

I checked out your Github thread... Did you ever find out what the original issue was? I am having the exact same problem. Just a slightly different J-Link box.
