Logging in multi-domain environment
Overview
This sample demonstrates the multidomain logging feature in Zephyr on a dual-core SoC. It uses a HOST/REMOTE architecture where the HOST core aggregates log messages from the REMOTE core via the IPC service, so output from both cores appears in a single terminal.
Requirements
This sample requires a board with dual-core support and IPC capability. The following targets are supported:
nrf5340dk/nrf5340/cpuappnrf5340bsim/nrf5340/cpuapp
Building and Running
This sample can be built and flashed on the nrf5340dk as follows:
west build -b nrf5340dk/nrf5340/cpuapp --sysbuild samples/subsys/logging/multidomain
west flash
Sample Output
The following lines are expected to appear in the HOST UART output (the order may vary):
Hello World! nrf5340dk
<inf> app: IPC-service HOST [INST 1] demo started
<inf> app: loop: 0
<inf> app: ipc open 0
<inf> app: wait for bound
<inf> app: ipc open 0
<inf> app: bounded
<inf> app: REMOTE [1]: 0
<inf> app: HOST [1]: 1
...
<inf> app: IPC-service HOST [INST 1] demo ended.
