ESP-IDF GDB OpenOCD Debugging issue

[WardMas]

Hi,
I am trying to debug hello_world example using ESP-IDF GDB OpenOCD Debugging in Eclipse 2020-12 with ESP-IDF 4.2V with the default settings. However, the debug does not start in any way and I am always getting the same debug log as shown below. Even when modifying config option to suit the board I am using (ESP32-Ethernet-Kit V1.1) to be:

Code: Select all

  -s ${openocd_path}/share/openocd/scripts -f interface/ftdi/esp32_devkitj_v1.cfg -f board/esp32-ethernet-kit-3.3v.cfg

no change has occurred and the debug could not start. I also tried slowing the adapter speed to be 10 KHz but that did't help too.
Is there anything I am missing here? any help?

Code: Select all

I have had the same issue. running on Windows7SP1. Same everything except booting Windows 10 and the system finds the right parts from the LibUsb call. I have not built the winUSB library, yet. I expect the issue is that some prior program load added a version of the libusb that is prior to the 6.x needed by openOCD. It has been almost long enough since I chased a bad DLL in microsoft land that I may sometime do it again. In the meantime I am putting together a replacement win10 only box with limited toys to use as a development system.
