Help setting up openocd with ST-LINK in WSL2

ArduPlane
1

Hello,

Following this guide I am trying to set up hardware debugging with the following hardware:

Software/Configuration:

  • Latest Arduplane firmware
  • WSL2. Everything happens inside the WSL2 (coding, building, etc) according to this guide.
  • BRD_OPTIONS = 9 (tried also 8)
  • sudo apt install openocd
  • this is my ./build/Arduplane/bin/openocd.cfg file
source [find interface/stlink-v2.cfg] # tried also stlink.cfg and stlink-v2-1.cfg
source [find target/stm32f7x.cfg]
init
$_TARGETNAME configure -rtos auto

I get the following output when I run openocd (tried with sudo as well)

Error: open failed

Did not move to the next steps (setting up GDB) as there was no point. I suspect the error has to do with fact that I am using WSL2 instead of native Ubuntu. Any ideas?

EDIT

Needed to install USBIPD (instructions for windows10 if anyone faces issues here) for usb forwarding in WSL2. Now the error is different. According to this video this is solved by setting BRD_OPTION to 9. Tried it, however without any luck.

Solved.

It was actually a wrong connection issue. So the steps above work, if anyone faces similar issues with debugger in WSL2.
