Works like a charm, thank you.

Hi,

You can add BOARD_ROOT to the CMakeLists.txt or the build command.

With west build:

west build -b my_custom_board -- -DBOARD_ROOT="board_root_path"

In CMakeLists.txt you must make sure to add the BOARD_ROOT before find_package:

list(APPEND BOARD_ROOT board_root_path)

find_package(Zephyr REQUIRED HINTS $ENV{ZEPHYR_BASE})

Note that the board root is the directory that includes the boards directory. In your example with main_folder/boards/arm/hw01, the board root will be main_folder.

Best regards,
Marte

Thank you for the reply, it seems very promising, but I need some additional help for this issue

My arborescency looks like this:

main_folder
    |_ project_1
        |_ CMakeLists.txt
        |_ CMakePresets.json
        |_ source files
    |_ project_2
        |_ CMakeLists.txt
        |_ CMakePresets.json
        |_ source files
    |_ boards / arm
        |_ hw01
            |_ board.cmake 
            |_ hw01_defconfig
            |_ hw01-pinctrl.dtsi
            |_ Kconfig.board
            |_ [...]
        |_ hw02
        |_ hw03

In the VSCode config, the boards we defines can be found in the different projects thanks to the following parameter:

    "nrf-connect.boardRoots": [
        "${workspaceFolder}/boards",
        "${workspaceFolder}/project_1/boards",
        "${workspaceFolder}/project_2/boards",
    ],

But when I go to main_project/project_1 and I enter the west command it cannot fine the defined boards :

CMake Error at /home/aurelien/ncs/v2.6.1/zephyr/cmake/modules/boards.cmake:167 (message):
  Invalid BOARD; see above.
Call Stack (most recent call first):

  CMakeLists.txt:18 (find_package)

-- Configuring incomplete, errors occurred!

How can I add the path to the boards directory in the shell environment so west is able to find it ?

Please note that the "board" is set in the CMakePresets, for instance :

{
            "name": "build_hw02",
            "displayName": "Build for hw02",
            "generator": "Ninja",
            "binaryDir": "${sourceDir}/build_hw02",
            "cacheVariables": {
                "NCS_TOOLCHAIN_VERSION": "NONE",
                "BOARD": "hw02",
                "CONF_FILE": "${sourceDir}/prj.conf",
                "_CMAKE_PRESET_NAME": "${presetName}"
            }
        },

Many thanks for your precious support.

Best regards

Hi Aurélien,

You can build using a preset by adding the --preset flag to the build command:

west build -d ${targetDir} -- --preset ${presetName}

For example, if you have a build directory called build_dir and the following preset with the name my_preset:

{
    "version": 2,
    "cmakeMinimumRequired": {
        "major": 3,
        "minor": 20
    },
    "configurePresets": [
        {
            "name": "my_preset",
            "displayName": "Build for nRF7002 DK nRF5340 application MCU",
            "generator": "Ninja",
            "binaryDir": "${sourceDir}/build_dir",
            "cacheVariables": {
                "NCS_TOOLCHAIN_VERSION": "NONE",
                "BOARD": "nrf7002dk_nrf5340_cpuapp",
                "CACHED_CONF_FILE": "${sourceDir}/prj.conf"
            }
        }
    ]
}

Then you can use the following command to build on command line using the preset:

west build -d build_dir -- --preset my_preset

Make sure that the build directory in the preset (binaryDir) matches the build directory provided in the west build command.

Best regards,
Marte
