    You can configure each project to use a specific ST-Link by explicitly saying which ST-Link S/N to use.
    To set specific ST-Link S/N you need to open Debug Configurations->Debugger and there in OpenOCD Options type "-c hla_serial xxxxxxxxxxxxxxxxxxxxxxxx"
    To get your ST-Link's serial you can use ST-Link Utility or STM CubeProgrammer

    Hi Riccardo,

    You can debug several boards in parallel with the same SW4STM32 and so the same workspace.

    To do that:
    - two projects, one for each custom board (on the same workspace)
    - two debug configuration (one for each project)

    Now you need to precise for each debug configuration, what is the board concerned.
    Two possibilities in the debugger tab:
    - using the STLink Server if the tool is installed on your machine OR
    - using the openocd option : "-c hla_serial XXXXXXX" (where XXXXX is the ST-Link SN number that you can get through ST-Link Utility or STM CubeProgrammer)

    Furthermore, if you debug the two projects in parallel, you must to define a different port number in the debug configuration (debugger tab).
    Example 3333 for one and 3334 for the other.

    Hi Elliot,

    Any idea how to do your suggestion on PlatformIO IDE? I want to use several boards and would like to manage uploading on remotely using 2 st link, howerver, I am experiencing this error when having two ST-Link connected at the same time, but works just fine when I upload with one programmer on connected on the remote device
    Warn : UNEXPECTED idcode: 0x1ba01477
    Error: expected 1 of 1: 0x2ba01477
    in procedure 'program'

      • OpenOCD init failed **

    shutdown command invoked

    Thanks and hoping for your consideration. Beginner on programming here.

    BR,
