How to connect the JTAG espressif esp-prog T5 epaper board

[KlaasVortex]

How do I connect the JTAG to the T5 epaper board ?

I think with a much bigger picture of the Product Pin Diagram I can look it up. The raspberry pi connector is unreadable.

I dont think it is possible to connect the PRG board a JTAG controller for Debugging. (I can be wrong here) However the ESP S3 has an internal USB JTAG debugger. This can be used in Arduino IDE by selecting JTAG debugger -> Intergrated USB JTAG

@KlaasVortex Do you know, if the debugging via the integrated USB JTAG can also be activated in VS Code with Platform IO?

You can refer to this, also for ESP32S3 https://rowa.tech.blog/2024/10/04/esp32-s3-debugging-via-usb-jtag-interface-in-vscode-platformio/

@lewisxhe Thank you. The guide helped me to get started. At the moment I had additionally to add debug_tool = esp-builtin in the platformio.ini in order that the debugger can connect to the device. However, currently the debugger does most of the time not halt at a break point, and if does, then at a wrong position or it does not continue, respectively halts a the same line when I execute continue.

Here the extract of my c code, where it always breaks a line esp_task_wdt_init(120, false);.

void setup() {
    // Disable Task Watchdog Timer
    esp_task_wdt_init(120, false);

    ... other code

The output of the debug log is

Do you have any guess what it could be? Also, I am using a mac with version 12.7.6 (21H1320).
