nRF5340 sample apps fail to build

Parker Lloyd

Hi,

NCS Version: 2.5.0

Zephyr RTOS Version: 3.4.99

Zephyr Toolchain Version: 0.16.4

I attempted to build some of the sample apps for the nRF5340

  • Multiprotocol RpMsg
  • Remote Shell

But the builds always fail due to the error below occuring numerous times:

fatal error: openamp/open_amp.h: No such file or directory

Has this been observed before? Where should I begin looking to resolve this? Are the SDK versions too old?

Best Regards,

Parker

    Hi,

    I've attempted to build the two samples you mention now in NCS 2.5.0 and I unfortunately don't see the same error message as you did for the remote shell and saw a successful build instead:

    NCS 2.5.0, using the corresponding toolchain, and building from terminal using "west build -b nrf5340dk_nrf5340_cpuapp -p"

    I assume you're using the VS Code extension, right? If so, could you verify if both the toolchain and SDK version has been set to match, i.e both being 2.5.0?

    Do you see the same result when you're using a pristine, unmodified sample? https://github.com/nrfconnect/sdk-nrf/tree/v2.6.0/samples/nrf5340/remote_shell 

    Kind regards,
    Andreas

    Sorry for the false alarm. We are using a devcontainer that is pulling from a forked Zephyr repo -- among some other peculiar configuration options.

    I have installed the SDK locally and the issue is not present anymore. Thanks for your help.
