ESP32-S3-WROOM-1 Unable to flash using JTAG with an ESP-PROG using ESPRESSIF-IDE

[wreyford]

I understand that you would expect me to use the built in JTAG, but that too doesn't work, and I actually want to Debug and Flash our custom board with an ESP32-S3 that already has the JTAG pins broken out to a header.

So to exclude any hardware issues, I decided to start with a ESP32-S3-WROOM-1 board.
All tooling installed in ESPRESSIF IDE, as per the official plugin documentation. Compiling, and flashing over UART works just fine.

Espressif IDE

Espressif-IDE is an Integrated Development Environment(IDE) based on Eclipse CDT for developing IoT Applications using ESP-IDF framework.

Version: 2.6.0
Build id: 20220811-0838

I have connected the header on the ESP-PROG, as per the documentation and rechecked it many times

On the ESP32 S3 side, I connected to 3V3, GND and the JTAG pins (in light blue) as in the image below.

The launch config has been setup as follows:

The console output is as follows if I just press the RUN button with the selected config in Espressif IDE.

And if I press and hold boot, then reset and release reset, then release boot, and then RUN from the IDE the output differs.

Also note from the console output, that I have reduced the speed to 10MHz

I hope you can help me resolve this issue, so that I too can enjoy debugging.

As per default configuration, ESP32S3 comes with NOT being able to use the JTAG pins.
You need to set a efuse in order to enable JTAG pins 39 to 42.
