Unable to build blinky project outside SDK folder

Suhas_MS

Hello,

I am unable to build basic blinky project outside the NRF Connect sdk.

Board - Thingy 91 - nRF9160

SDK version - 1.7.0

builiding through command line tools - CMake and Ninja (windows)

I have provided build variables in the Cmakelists.txt as below.

# SPDX-License-Identifier: Apache-2.0

cmake_minimum_required(VERSION 3.20.0)

set(ZEPHYR_TOOLCHAIN_VARIANT gnuarmemb)
set(GNUARMEMB_TOOLCHAIN_PATH C:/coresensing/toolchain/gnuarmemb)
set(ZEPHYR_BASE C:/coresensing/toolchain/ncs/zephyr)
set(BOARD_ROOT C:/coresensing/toolchain/ncs/nrf)

find_package(Zephyr REQUIRED HINTS $ENV{ZEPHYR_BASE})
project(blinky)

target_sources(app PRIVATE src/main.c)

My application directory is as follows,

- Workspace

   - Blinky

      - src

         - main.c

      -CMakelists.txt

      -prj.conf

This is the Cmake error I am getting

    Hello Suhas,

    have you installed the nRF Connect SDK according to this guideline and performed all steps?

    Is there a reason why you are using this build command?

    cmake -B build -GNinja -DBOARD=thingy91_nRF9160_ns

    Normally, we recommend to use this one instead:

    west build -b thingy91_nrf9160ns

    Regards,

    Markus

    Yes I have installed nRF Connect SDK according to the guideline. This can be confirmed because, the application compiles correctly inside the SDK.

    I need a freestanding application.

    the west command will not build anything,

    PS C:\Users\Suhas\eclipse-workspace\blinky> west build -b thingy91_nrf9160ns
usage: west [-h] [-z ZEPHYR_BASE] [-v] [-V] <command> ...
west: error: argument <command>: invalid choice: 'build' (choose from 'init', 'update', 'list', 'manifest', 'diff', 'status', 'forall', 'help', 'config', 'topdir', 'selfupdate')
PS C:\Users\Suhas\eclipse-workspace\blinky>

    thank you.

    Hello Suhas,

    Suhas_MS said:
    I need a freestanding application.

    Got you!

    You might want to have a look at the section Adding your own code in the NCS documentation. I will provide you with an example based on Workflow 4: Application as the manifest repository.

    In the root folder of your freestanding Blinky sample, create a file named west.yml containing the following:

    # Example application-specific west.yml, using manifest imports.
manifest:
  remotes:
    - name: ncs
      url-base: https://github.com/nrfconnect
  projects:
    - name: nrf
      repo-path: sdk-nrf
      remote: ncs
      revision: v1.6.1
      import: true
  self:
    path: blinky_app

    path should be the root folder name of the Blinky sample, which in this case “blinky_app”. NCS version to be used in this example will be v1.6.1, but this can be changed to basically any other version.

    Now, in your workspace folder where “blinky_app” is the manifest repository, run the following command:

    west init -l blinky_app

    followed by:

    west update

    When finished, you should have a full nRF Connect SDK repository within your workspace. Switching to “blinky_app”, you can now run the build command:

    west build -b thingy91_nrf9160ns

    followed by:

    west flash --erase

    I hope this will help you.

    Regards.

    Hello Markus,

    I have already tried this approach and this downloads the whole SDK again to my workspace.

    I need to implement an application out of the SDK directory as given in - 

    Workflow 2: Out-of-tree application repository

    This approach will help us maintain the application only with our repository and decouple it with NRF SDK. That is the reason why I have added ZYPHER_BASE to my CMakelists.txt

    but this approach doesn't seem to work.

    Please let me know how I can establish the out-of -tree application repository properly.

    Thank You.

    Hello Suhas,

    Suhas_MS said:
    Please let me know how I can establish the out-of -tree application repository properly.

    I will demonstrate this based on the Hello World sample on an Ubuntu distribution. The installation path of the nRF Connect SDK is "$HOME/ncs", resulting in:

    ~$ echo $ZEPHYR_BASE
/home/user/ncs/zephyr

    In addition to all other required tools, the variable has to point to the right Zephyr within your build environment.

    Now I just copy the hello_world folder from "$HOME/ncs/zephyr/samples/hello_world" to a different location, e.g. "$HOME/_work/outoftree/".

    From there, I run:

    ~/_work/outoftree/hello_world$ west build -b nrf9160dk_nrf9160ns

-- west build: generating a build system
