ESP32 debugging working using a ESP-PROG board together with an ESP32-S3 dev board

[MichaelS]

I am trying to get ESP32 debugging working using a ESP-PROG board together with an ESP32-S3 dev board.

I am using VSCode with IDF ver 5.3. I have tried following a few guides and videos but they are a little different and some are out of date.

So far:

I have connected up the JTAG interface pins from the debug board to the ESP32-S3 as follows.

Code: [Select all] [Expand/Collapse]

1. Debug board                  ESP32-S3
2. TDI --------------------------GPIO41 pin 41
3. TDO ------------------------GPIO40 pin 40
4. TCK-------------------------GPIO39 pin 39
5. TMS-------------------------GPIO42 pin 42
6. VJTAG----------------------3v3

I used Zadig to update my drivers for the dual RS-232 0

Windows device manager shows:
Under Ports (COM & LPT)
USB Serial CH343 (COM19)
USB Serial Port (COM20)

and under USB Devices
DUAL RS232-HS

In a terminal I run:

Code: [Select all] [Expand/Collapse]

1. PS .....> openocd --version
2. Open On-Chip Debugger v0.12.0-esp32-20240318 (2024-03-18-18:26)
