.vscode cfg file not found by openocd

[niekez]

When I start debugging it times out. When I enable debugging in cortex-debug I get this command (I use the gnu mcu eclipse version):

$ "/home/niek/opt/npm/bin/openocd" "-c" "gdb_port 50000" "-s" "/home/niek/Documents/code/base/disc_spi" "-f" "/home/niek/opt/xPacks/@gnu-mcu-eclipse/openocd/0.10.0-12.1/.content/scripts/interface/stlink.cfg" "-f" ".vscode/stm32l4x.cfg"

This is the output:

Changing the .vscode line to a absolute path launches the debugger:

"/home/niek/opt/npm/bin/openocd" "-c" "gdb_port 50000" "-s" "/home/niek/Documents/code/base/disc_spi" "-f" "/home/niek/opt/xPacks/@gnu-mcu-eclipse/openocd/0.10.0-12.1/.content/scripts/interface/stlink.cfg" "-f" "/home/niek/opt/xPacks/@gnu-mcu-eclipse/openocd/0.10.0-12.1/.content/scripts/target/stm32l4x.cfg"

Or when I change the launch.json to the following:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Cortex debug",
            "type": "cortex-debug",
            "request": "launch",
            "servertype": "openocd",
            "cwd": "${workspaceFolder}",
            "executable": "build/disc_spi.elf",
            "svdFile": ".vscode/STM32L4x6.svd",
            "showDevDebugOutput": true,
            "configFiles": [
                "interface/stlink.cfg",
                "target/stm32l4x.cfg"
            ],
            "preLaunchTask": "Build project"
        },
        {
            "name": "Debug current Python file",
            "type": "python",
            "request": "launch",
            "cwd": "${workspaceFolder}",
            "program": "${file}",
            "console": "integratedTerminal"
        }
    ]
}

It's working fine.

The problem I think lies in the fact it can't find the local cfg file. I would like to be able to enter the relative paths like the above but these aren't accept by updatePaths.py.

Absolute paths work but by copying the stm32l4x.cfg to the .vscode folder, openocd can't find it anymore.

Hmm. It would be very helpful if there would be other non-windows users - I am having a hard time since most of this issues are somehow linux related and I can't reproduce them. So, linux guys, speak up! :)

Anyway, paths can be relative. But, if file on a given relative path does not exist, this path is not a valid path and is rejected by the script. I don't know for sure if this is the problem, but still, what is this @ in your path? "... "-f" "/home/niek/opt/xPacks/@gnu-mcu-eclipse/openocd/0.10.0-12.1/.content/scripts/interface/stlink.cfg" ...? Also, I use OpenOCD version 0.10.0-8-20180512-1921, didn't check with your newer one.

For me the debugging at first didn't work with the openocd version from the system repository.

The relative paths are not accepted because the binary for openocd is in /usr/bin/openocd and the scripts folder is in /usr/share/openocd/. I can get around this by entering absolute paths.

I don't know for sure if this is the problem, but still, what is this @ in your path?

I used xpm to install the gnu-mcu-eclipse version of openocd, not ideal because it has version numbering in in the path.

I just found out that it didn't work because the cfg file in my .vscode folder was the system one, not gnu-mcu-eclipse one. So the problem wasn't not finding it but having a mismatch in version.

Using the gnu-mcu-eclipse version like recommended by cortex-debug works for me after replacing the target cfg in .vscode.

So in the end I used the latest release from here: https://github.com/gnu-mcu-eclipse/openocd/releases

And had to remove the target cfg from .vscode en update with the cfg files from gnu-mcu-eclipse. This also has an updated interface stlink.cfg which archlinux' openocd from the repository doesn't have.
