nRF5340 MultioCore example build failure

[SirBuhi]

Hi there,

In order to understand more about the MultiCore of the nRF5340, I'm trying to built the Multicore Hello World application, with nRF Connect SDK 2.3.0 as a "Workspace" application type.

Creating the files/application does work so far, but during the build process, it the the following failure bellow:

I have also tried it with the nRF Connect SDK 2.2.0, with the same result.

Kind regards,

Patrick

Hi Patrick,

Thank you for contacting DevZone at NordicSemi.

The sample "Multicore Hello World" is a sample from NCS 2.4.0.

As you are testing with NCS 2.3.0, may I ask to check out the multicore sample (nrf/samples/nrf5340/multicore) which is same as that of Multicore-hello-world.

Moreover, may I ask you to test the sample first with "Freestanding" application type from the VS Code.

Also, the command add_child_image() is not a standard CMake command, but rather defined as a function in sdk-nrf/cmake/multi_image.cmake

The issue, if you still face it, could be due to the order of entries in the yaml file, and it is discussed here for reference.

Regards,

Naeem

Dear Naeem,

The link used to point to the example you mentioned with NCS 2.3.0. Seems like the link has changed to the latest NCS release since the ticket creation and your response.

The sample is running on my machine as a "Freestanding" application, but as I mentioned, not as a "Workspace" application.

In regards of the entries in the west.yaml, there is not much what I can change:

manifest:
  remotes:
    - name: ncs
      url-base: https://github.com/nrfconnect
  projects:
    - name: sdk-nrf
      remote: ncs
      path: nrf
      revision: v2.3.0
      import: true
      clone-depth: 1
  self:
    path: multicore

Regards,

Patrick

Hi Patrick,

Yes, I can now see the same issue as you have described.

I do not know what is the cause of this issue, but I have reported it internally.

I will let you know if there is any update.

Naeem

Hi Naeem,

Any update on this? I got same issue under ncs v2.5 when using "

Workflow 4: Workspace application repository (recommended)

" methode.
