Sample ipc_service failed in NCS v2.3.0

[Hiihtaja]

 Hello !

I have compiled sampel ncs/v2.3.0/nrf/samples/ipc/ipc_service without any overlays west build -p --board nrf5340dk_nrf5340_cpuapp and west flash --recover it.

Looks like it doesn't work in new release

Network core traces

*** Booting Zephyr OS build v3.2.99-ncs2 ***

App core , only short line

Looks like some problem. I try to use this sample in own application and someting weired there as well.

Hi !

I think, very short interval is set by default

with CONFIG_APP_IPC_SERVICE_SEND_INTERVAL=20000

Traces are visible from both cores:

But

from what component come trace 

[00:00:00.520,477] <inf> sync_rtc: Updated timestamp to synchronized RTC by 8360 ticks (255126us)

RTC syncronization should be disabled by default ?
