| OpenAMP performance Sample Application |
| ###################################### |
| |
| Overview |
| ******** |
| |
| This application demonstrates how to measure OpenAMP performance / throughput |
| with Zephyr. |
| |
| Building the application for nrf5340dk_nrf5340_cpuapp |

| .. zephyr-app-commands:: |
| :zephyr-app: samples/subsys/ipc/openamp_performance |
| :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: |
