This setup works like this:

1) The `settings.json` file is, in theory, the only file you need to change according to your setup. Read its comments to know how to edit them.
2) The main file from the user perspective is `launch.json` since this file creates the rule `C++ Launch` called when the user wants to start debugging. This action fire other actions in this sequece:
  2.1) It sets the program to be debuged (see `program`);
  2.2) set the dependent tasks (see `preLaunchTask`)
  2.3) Set the initial GDB setup commands;
  2.4) Set the path to the cross debugger
  2.5) Set the IP to reach the board
3) `launch-remote-debug` task has several steps:
   3.1) Build the debug app in the host using petalinux (see `build` task)
   3.2) Update the Yocto package manager so that the board can reach the new version of the debugged package (see `"pkg-reindex` task);
   3.3) In the board, update the package to be debugged and run gdbserver.
4) Finally, VSCode return to the `launch.json` and attach the cross GDB in the host computer to the gdbserver running in the board.

Have Fun!
