Sorry, I somehow overlooked that. While I tested your code now I noticed your "IRQ_CONNECT" macro did not connect the driver's ISR, but the application callback. After changing that it worked:

Did you call nrfx_ipc_signal() to trigger the interrupt? I don't see the events being triggered in the code you posted here.

Thank you very much for pointing out your mistakes.

I added the entire following statement to both appcore and NETCORE:

IRQ_CONNECT(IPC_IRQn, 1, ipc_event_handler, 0, 0);

The interrupt is still not generated.

What method can I use to confirm that the IPC sending of appcore is valid and the interrupt receiving of NETCORE is successful? What more mistakes did I fail to notice?

Hello,

When working directly with nrfx driver APIs in the connect SDK you have to use the IRQ_CONNECT() macro as we do in the nrfx use example. Otherwise the interrupt vector will not get placed in the vector table.

Please note that this approach may conflict with the existing communication channel (https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_nrf5340.html#inter-core-communication) used in our examples.

Best regards,
