| IPC Service - icmsg - Sample Application |
| ######################################## |
| |
| Overview |
| ******** |
| |
| This application demonstrates how to use IPC Service and the icmsg backend with |
| Zephyr. It is designed to demonstrate how to integrate it with Zephyr both |
| from a build perspective and code. |
| |
| Building the application for nrf5340dk_nrf5340_cpuapp |

| :zephyr-app: samples/subsys/ipc/ipc_service/icmsg |
| :board: nrf5340dk_nrf5340_cpuapp |
| :goals: debug |
| |
| Open a serial terminal (minicom, putty, etc.) and connect the board with the |
| following settings: |
| |
| - Speed: 115200 |
| - Data: 8 bits |
| - Parity: None |
| - Stop bits: 1 |
| |
| Reset the board and the following message will appear on the corresponding |
| serial port, one is host another is remote: |
