west build failed due to mcuboot sysbuild

[DKC]

Hi,

With NCS v3.1.0 and Nordic's downstream zephyr ncs-v3.1.0, I got build failure with following message:

--

warning: attempt to assign the value 'n' to the undefined symbol MCUBOOT_HARDWARE_DOWNGRADE_PREVENTION

--

This failure can be reproduced by building sample 'with_mcuboot'.

Command as below:

west build -p always -b nrf52840dk/nrf52840 zephyr/samples/sysbuild/with_mcuboot --sysbuild

But I can succeed to build it without '--sysbuild'. And BTW, with same system (machine with Ubuntu v22.04 installed) I can build this sample with original 'zephyr' according to 'Getting Started Guide'

docs.zephyrproject.org/.../index.html

Hi Dunk,
I was not able to reproduce your issue, the sample works just fine on my machine. Could you please share your entire build log?

Regards,
Benjamin

Hi Benjamin,

Thanks for reply. The full log of building this sample was provided.

BTW, I'm working on the Ubuntu environment, not any GUI/IDE involved.
The steps I was used to initiate my development environment as below:

• python3 -m venv .venv
• source .venv/bin/activate
• pip install west

west initialization with west.yml as below

manifest:
  self:
    path: cbs

  remotes:
    - name: zephyrproject-rtos
      url-base: https://github.com/zephyrproject-rtos
    - name: nrfconnect
      url-base: https://github.com/nrfconnect

  projects:
    - name: zephyr
      remote: nrfconnect
      repo-path: sdk-zephyr
      revision: ncs-v3.1.0
      import: true
    - name: nrf
      remote: nrfconnect
      repo-path: sdk-nrf
      revision: v3.1.0
      import: true

• west update
• pip install -r zephyr/scripts/requirements.txt
• west sdk install -t arm-zephyr-eabi -b .
• west zephyr-export
• source zephyr/zephyr-env.sh
