| Multiple instance of RPMsg |
| ########################## |
| |
| Overview |
| ******** |
| |
| Multiple instance of RPMsg is an abstraction created over OpenAMP. |
| It simplifies the initialization and endpoint creation process. |
| This sample demonstrates how to use multi-instance RPMsg in Zephyr. |
