Did you install the driver required, as indicated here?

Well i solved the problem by uploading the proper libusb driver.
But now i am facing different issue with xtesna-esp32-elf-gdb.
i have successfully implemented the openocd step mentioned in document:
https://docs.espressif.com/projects/esp ... un-openocd.

Move to debugging using command line as mentioned.
i have follow exact step mention in below document:
https://docs.espressif.com/projects/esp ... -debugger-

Its seem to be remote connection unable to open mean its showing nothing after target remote :3333

If I recall correctly, that indicates that gdb cannot connect to OpenOCD. Do you have OpenOCD running at the same time? Perhaps there's a firewall blocking the connection?
