esp32 openocd error(at Command Line)

[Daniel.Kim]

Hi
I try to use the OpenOCD at first.

I finally coal is to use j-tag on the Visual Code IDE.
So I follow the recommend which explained how to set up the OpenOCD at the command line.

My OpenOCD path is "C:\Program Files\Espressif\ESP-IDF Tools\tools\share\openocd".
I installed the ESP-IDF Tools.
And I set the environment path. (C:\Program Files\Espressif\ESP-IDF Tools\mconf-idf, C:\Program Files\Espressif\ESP-IDF Tools\tools)

After then I open the terminal, go to the directory where OpenOCD is installed and start it up.
C:\Program Files\Espressif\ESP-IDF Tools\tools\share\openocd>openocd -f interface/ftdi/esp32_devkitj_v1.cfg -f board/esp-wroom-32.cfg

The result is an error.
C:\Program Files\Espressif\ESP-IDF Tools\tools\share\openocd>openocd -f interface/ftdi/esp32_devkitj_v1.cfg -f board/esp-wroom-32.cfg
