fixing issue with missing jsonschema for python

[ge0053]

when building a project i get an error from python which cant find the module jsonschema:

west build -p always -b adi_eval_adin1110ebz zephyr/samples/basic/blinky

CMake Error at zephyr/cmake/modules/boards.cmake:191 (message):
  Error finding board: adi_eval_adin1110ebz

  Error message: Traceback (most recent call last):

    File "zephyr/scripts/list_boards.py", line 13, in <module>
      import jsonschema

  ModuleNotFoundError: No module named 'jsonschema'

it would also be possible to specify that it is a necessary package in the flake file.
Tested with the example flake with these additions:

      packages=[
    zephyr-nix.packages.x86_64-linux.sdkFull-0_16
    zephyr.pythonEnv
    zephyr.hosttools
    pkgs.cmake
    pkgs.ninja
    #pkgs.python3Packages.jsonschema

      ];

zephyr-nix/python.nix

Line 95 in 39661e3

extraPackages = ps: [ ps.west ] ++ extraPackages ps;

is the proper place for you to make this change. I would not mind making this change, but it needs to be done there, not where you did. Also, you need to rebase your codebase so you can send this against the current codebase.

Same issue here. The dependency jsonschema is included in zephyr's requirements.txt: https://github.com/zephyrproject-rtos/zephyr/blob/main/scripts/requirements-base.txt#L15, which should be handled by pyproject-nix's parser.

However, after some poking (as is shown below), it seems that only jsonschema is left out when pyproject-nix parses the requirements.txt , which is quite strange.

And updating pyproject-nix 's flake rev from 02e9418f to latest 02e9418f does not address the issue, so if it is an upsteam bug, it's not fixed yet.

I was looking at the wrong rev, it should be https://github.com/zephyrproject-rtos/zephyr/tree/v4.1.0 and jsonschema wasn't a dep back then. In my case the error was because $WEST_WORKSPACE/zephyr and the zephyr-src tracked in flake have mismatched version. West calls a python script in the former (which depends on newly introduced jsonschema), in the environment that zephyr-nix created tracking the latter (which does not have jsonschema). @ge0053 Please check if this is also the root cause for you. If so this PR would be unnecessary...
