| |
| Send messages between two cores using OpenAMP. |
| |
| Overview |
| ******** |
| |
| This application demonstrates how to use OpenAMP with Zephyr. It is designed to |
| demonstrate how to integrate OpenAMP with Zephyr both from a build perspective |
| and code. Note that the remote and primary core images can be flashed |
| independently, but sysbuild must be used in order to build the images. |

| 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 master another is remote: |
