ESP-Prog board + Eclipse openocd for ESP32WROOM not working

Postby mikeBohm » Tue Apr 13, 2021 3:21 pm

Hello
trying to get esp debugging started. Im working on win 10. Ive installed the winusb driver using zadig.
I followed this guide to set up the esp idf environment for eclipse:
https://www.beyondlogic.org/debugging-with-jtag/
But I get various error when i try to debug:

this is my debugger conf:

startup menu:

These errors I get on the first run, after starting eclipse with a power cycled esp board:

and after a while I get a time out.
restarting the debug session gives the following print:

does the
Error: libusb_open() failed with LIBUSB_ERROR_NOT_SUPPORTED
have anything to do with it? Ive tried what I know to get rid of that error, reinstalling WinUsb drivers back and forth with Zadig and device manager but no success, any ideas?
I can program the chip using idf.py so the chip is not bricked..
