Multi-Core Samples for nRF54H20

[Kyle]

Hello,

Are there any samples that show multi-core (sysbuild) configurations for the nRF54H20?

I've found the sysbuild HelloWorld project, but in the sysbuild.cmake file it only supports the nRF53X and nRF54LX series (not nRF54HX).

Hi,

 

I see the confusion, and I must apologize for this. I will bring this up with our UX group internally.

 

The sample pointed to in the docs is in the zephyr repo, more specifically this one:

https://github.com/nrfconnect/sdk-zephyr/tree/main/samples/sysbuild/hello_world

ie. ncs/zephyr/samples folder, not the ncs/nrf/samples/zephyr folder.

 

Kind regards,

Håkon

Thank you. I did notice that there are separate .conf files for each target board in the sysbuild directory.

Could you provide a bit of info/context on why there are special configuration options for the 53X and 54LX in the sysbuild.cmake file, but not for the other boards like the 54HX?

Hi,

 

nRF53 needs configurations to enable the netcore, and similar with the nRF54L-series FLPR.

The nRF54H also has SB required configurations, as stated here in the docs:

https://docs.nordicsemi.com/bundle/ncs-latest/page/zephyr/samples/sysbuild/hello_world/README.html#building_and_running

These are loaded via these lines:

Kind regards,

Håkon
