How to debug hardware or baremetal via openocd?

[InLAnn (inlann)]

Hello:

I have already debugged a baremetal (a hardware board) in terminal using openocd:

1. launch openocd: /path/to/openocd -c "gdb_port 33333" -c "tcl_port disabled; telnet_port disabled" -f "/path/to/openocd_configfile"
2. start gdb: gdb -ex "target remote 127.0.0.1:33333" -ex "monitor reset halt" -ex "load /path/to/openocd_configfile"

I'm trying to do it in VS Code. So I need to modify the tasks.json and launch.json:

1. tasks.json:

{
  // See https://go.microsoft.com/fwlink/?LinkId=733558
  // for the documentation about the tasks.json format
  "version": "2.0.0",
  "tasks": [
      {
          "label": "launch OpenOCD",
          "type": "shell",
          "command": "/path/to/openocd -c 'gdb_port 33333' -c 'tcl_port disabled;telnet_port disabled' -f /path/to/openocd_configfile &"
      }
  ]
}

2. launch.json:

{
  // Use IntelliSense to learn about possible attributes.
  // Hover to view descriptions of existing attributes.
  // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
  "version": "0.2.0",
  "configurations": [
      {
          "name": "(gdb) Launch",
          "type": "cppdbg",
          "request": "launch",
          "program": "${workspaceFolder}/helloworld.elf",
          "args": [],
          "stopAtEntry": false,
          "cwd": "${fileDirname}",
          "environment": [],
          "externalConsole": false,
          "MIMode": "gdb",
          "miDebuggerPath": "/usr/bin/gdb",
          "miDebuggerArgs": "-ex 'target remote 127.0.0.1:33333' -ex 'monitor reset halt' -ex 'load ${workspaceFolder}/helloworld.elf'",
          "setupCommands": [
              {
                  "description": "Enable pretty-printing for gdb",
                  "text": "-enable-pretty-printing",
                  "ignoreFailures": true
              }
          ],
          "preLaunchTask": "launch OpenOCD"
      }
  ]
}

It seems like the executable file path ${workspaceFolder}/helloworld.elf in miDebuggerArgs is duplicated with the program and the miDebuggerPath is redundant.

Can I simplify them by adding some debugger args to remove the miDebuggerPath and the miDebuggerArgs?
