Hi
Long time no see 
I recently got my sweaty hands on a sparkly new 54L15DK, and I thought I would try it out. The AI guided me to the coremark sample and the multicore/hello_word sample, but I couldn't find the hello_world sample anywhere in NCS v2.8.0. Is this sample no longer included?
I am looking for a very basic sample showing how to enable the two cores, and exchange data between them.
Best regards

Hi Hieu
Thanks a lot for the clarification.
Do you know how I should build the sample then?
I tried building the ipc_service/icmsg sample for the 54L appcore with the nordic-flpr snippet selected, but this won't work:
I tried attaching the build log, but attaching files or text is not really working today 
Are you supposed to build the sample twice, once for each core, or will sysbuild ensure that a single build can target both the appcore and the FLPR core?
Best regards
Torbjørn
Hi Torbjørn,
The snippet needs to be applied only to the cpuapp. When you provide snippet like that, it gets applied to all images.
You will need to use the extra CMake argument menu instead and then put the <application name>_ between -D and SNIPPET, like when you add an extra Kconfig only to a specific image.
For example, my application folder is named icmsg_280, so I specified -Dicmsg_280_SNIPPET=nordic-flpr.
And then you build the sample just once with sysbuild. The remote image will be built automatically from the sysbuild setup. Flashing will also automatically include both cores.
Getting to this point isn't straight forward, sorry. I will relay this experience with the relevant team.
