Hello,

yes, I have looked at the application.

Which version of NCS you are using? Did you try to run the application on the DK? I can see there is no configuration in your prj.conf file.

''I've run the multicore example successfully, and I'm now a bit further, stuck on a situation a bit annoying.'' Do you mean multicore hello_world sample? In NCS v2.9.0, we do not have this sample but instead there is hello_world in the sysbuild sample. You can try to run that sample on your custom board first and see if it works for both cores.

The build command looks like this.

Hi !

I looked at the documentations you send, they're usefull ! Thanks !

But I'm always stuck at this point, I've added the following instruction:

nrf_reset_network_force_off(NRF_RESET, false);

As I've seen on many forums, but the network core does not seems to be booting anyway (it remains on the same instruction as before).

And, what did you mean by application file ? Did I forget some file on the github repo ?

Thanks !

PS : I don't want the case to be private, because this is not private nor sensible, and may help many others here!

Hello,

It seems like something related to the application core not releasing the network core from FORCE-OFF mode to allow it to start executing code. Can you please read this https://docs.nordicsemi.com/bundle/ps_nrf5340/page/chapters/pmu/doc/pmu.html#ariaid-title6 here?

You can send the application file so I can look at this form my side. I can make the case private.

Thanks.
