ST-LINKV3 over VirtualHere (USB over IP)

[lakins]

Hello,

I am trying to share ST-LINKV3 over the network and use it from another PC (WSL Ubuntu distro running docker and connecting to ST-LINKV3 via OpenOCD) with VirtualHere program (client and server), but facing this issue:

Info : auto-selecting first available session transport "hla_swd". To override use 'transport select <transport>'.
Info : The selected transport took over low-level target control. The results might differ compared to plain JTAG/SWD

 Is it doable at all?

This is the recommended way to do remote debugging:

What would be the proper way to do it with openocd?

GDB Server will be running on Windows machine, and client will be connecting to flash/debug from Ubuntu.

Just to note environment is VSCode/CMake.

Looks like OpenOCD works the same:
