ESP32 Forum

Hello,

I have received an esp32-s3-devkitm-1 board and tried flushing and debugging the blink example on it.
I have followed many threads on the subject and replaced the driver in many options and almost to all available driver.
But all solution could not solve it for me.

Then I realized that ESP-IDF tools provide an inf file in which device Hardware ID (VID_303A&PID_1001&MI_02) is different from the Hardware ID as it recognized by windows (USB\VID_303A&PID_4001&MI_00)
The result is that the device is never recognized as usb_jtag_debug_unit and therefore the wrong driver is loaded, and openOCD can not find it.

I tried changing only the setting at esp_usb_jtag.cfg so it will search for PID 4001 instead of 1001 but bellow is what openOCD printed out:
Info : only one transport option; autoselect 'jtag'
Info : esp_usb_jtag: VID set to 0x303a and PID to 0x4001
Info : esp_usb_jtag: capabilities descriptor set to 0x2000

Info : esp_usb_jtag: VID set to 0x303a and PID to 0x4001

Error: libusb_open() failed with LIBUSB_ERROR_NOT_SUPPORTED
Info : esp_usb_jtag: serial (123456)
Error: esp_usb_jtag: error finding/claiming JTAG interface on device!

Does any one encounter that problem? do you have any solution to it?

Thanks in advance

You likely have firmware in the S3 that uses the USB-OTG peripheral and you're seeing that rather than the USB-serial-JTAG. Suggest you turn on the S3 in download mode, i.e. hold 'boot', press and release 'reset' and release 'boot' and try again; you should be seeing the USB-serial-JTAG then. (Obviously, you also need to change your openocd config back.)

Wow!!
That was on the spot!!!
Thanks a lot!!!
I could not find such instructions anywhere

Hi again,

Thanks to ESP_Sprite my esp32-s3-devkitm-1 was identified by Windows 10 as "USB/Serial debug unit" When "Restoring to default driver" using "USB Driver Tool" I found the following listed in device manager:
USB JTAG/serial debug unit (interface 0) (COM17)
USB JTAG/serial debug unit (interface 2) (COM16)
And USB Composite device is also recognized with the same DevID
Trying to install either WinUSB or Libusb-WinUSB using "USB Driver Tool" or using "Zadig 2.8" to either install "WinUSB (Microsoft)", "libusb-win32", "WinUSB (libusb)" or libusk result with COM port disappearing.
Only when returning to "USB Serial (CDC)" the COM port apeared again and flash_erase and flash were possible using the UART as a flashing port.
But I could not by any way use the jtag for debugging.
Any suggestion to what I'm doing wrong?

I'm not really familiar with Windows, but I think you specifically need to install winusb on the 2nd interface, not on interface 0 or the composite device itself. You could also see if you can reinstall ESP-IDF using the Windows installer ( https://dl.espressif.com/dl/esp-idf/ ); I think that also installs the drivers properly.

Hello ESP_Sprite,

So far you have been most helpful, but unfortunately I still couldn't debug the blink example through the jtag.
I have installed the WinUSB driver for the 2nd interface.
I now have interface 0 as the UART connection and I'm able to flash and erase.
my setting.json look like that :
{
"C_Cpp.intelliSenseEngine": "Tag Parser",
"idf.adapterTargetName": "esp32s3",
"idf.openOcdConfigs": [
"board/esp32s3-builtin.cfg"
],
"idf.flashType": "UART",
"idf.portWin": "COM4"
}

Interface 0 is connected to COM4

but when executing \blink> openocd.exe -f board\esp32s3-builtin.cfg
The following output is printed.
When board in download mode:

and so on....

I am obviously doing something wrong, but I can not figure out what it is.
Do you recommend moving to Linux?
Do you have any other suggestion?

Thank for helping me so far, and thank in advance if you can give me the right instructions.
