ESP32 Forum

Hello everyone,

I am trying to debug my ESP32-S3 using ESP-PROG and OpenOCD, but I am encountering an issue where OpenOCD fails to detect the JTAG device.

Setup Details:
Debugger: ESP-PROG
Target Board: ESP32-S3
OS: Windows
Driver Setup: Installed FTDI driver using Zadig
OpenOCD Command Used:
bash
Copy
Edit
openocd -f board/esp32s3-builtin.cfg


Issue & Error Log:
When running the above command, I get the following error:

Open On-Chip Debugger v0.12.0-esp32-20240821 (2024-08-21-14:45)

Expected Output:
I was expecting a log similar to this:

Info : esp_usb_jtag: Device found. Base speed 40000KHz, div range 1 to 255
Info : clock speed 40000 kHz
Info : JTAG tap: esp32s3.cpu0 tap/device found: 0x120034e5 (mfg: 0x272 (Tensilica), part: 0x2003, ver: 0x1)
Info : esp32s3.cpu0: Debug controller was reset.
Info : Listening on port 3333 for gdb connections

Request for Help:
Has anyone faced this issue before?
Are there any additional driver configurations needed for OpenOCD to detect ESP-PROG?
Could this be an issue with my OpenOCD version or ESP-IDF setup?
Any suggestions or troubleshooting tips would be greatly appreciated!

Thanks in advance!
