Have you ever encountered?
When using the ESP32-S3 module with ESP-IDF version idf 5.0, debugging JTAG, you try for a long time but cannot connect, why is that?

What’s going on?
This process requires installing zadig for debugging,you need to install the WINUSB driver for interface 0 and interface 2 simultaneously.

Debugging the issue
With the USB JTAG (Interface 2) driver installed, start debugging JTAG by executing “openocd -f board/esp32s3-builtin.cfg”, this command starts OpenOCD, but an error occurs:
In the JTAG documentation, it is mentioned: for custom boards with FT2232H or FT232H chips for JTAG connection, or custom boards with ESP-Prog, you can execute “board/esp32s3-ftdi.cfg”, it is recommended that customers try both, but still cannot connect.

Windows Testing Environment
In the Windows environment, first download the hello project via UART to enter the module, then call “openocd -f board/esp32s3-builtin.cfg”, it will print information every 10 seconds; due to a reboot reason, switch to flashing the blink example, then start openocd, you should be able to run idf.py gdb directly in the blink directory, which should stop at app_main.
However, the actual test result when running idf.py gdb in the blink directory requires entering some commands for recognition (as shown below), and there is no response in openocd.
Finally, it was confirmed that idf.py gdb has issues on Windows, and I tried again using xtensa-esp32s3-elf-gdb -x build/gdbinit connect build/blink.elf. Ultimately, using xtensa-esp32s3-elf-gdb -x build/gdbinit connect build/blink.elf command test was successful.

Solution
Install zadig, you need to install the driver for interface 0 as WINUSB, and also install for interface 2 as WINUSB, set up the environment on Windows, compile and flash the blink example, open a second terminal, and use the commandsudo apt install openocd to install openocd, then run the commandopenocd -f board/esp32s3-builtin.cfg, the result is:
Return to the terminal downloading blink and enter the command idf.py gdb, a build/gdbinit/connect file is generated in this project, and the result is as follows:
Then enter q in the command line and press enter to exit that interface; finally, enterxtensa-esp32s3-elf-gdb -x build/gdbinit/connect build/blink.elf and you will get the following running result, at this point JTAG has run successfully.
