Multicore sample for the 54L15

[ovrebekk]

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
Torbjørn

Hi Torbjørn,

The AI is confused. The sample you want is zephyr\samples\sysbuild\hello_world.

Exchanging data between them is unfortunately not demonstrated there though :/

Best regards,

Hi Torbjørn,

For communication between the cores, you use IPC, same as the nRF5340. The sample is here: sdk-zephyr/samples/subsys/ipc/ipc_service/icmsg at v3.7.99-ncs1 · nrfconnect/sdk-zephyr

You will also need to use the snippet nordic-flpr.
