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.

:zephyr-app: samples/subsys/ipc/rpmsg_multi_instance
|
|
:board: nrf5340dk_nrf5340_cpuapp

|
|
Open a serial terminal (for example Minicom or PuTTY) and connect the board with the following settings:
|
|
|
|
- Speed: 115200
|
|
- Data: 8 bits
|
|
- Parity: None
|
|
- Stop bits: 1
|
|
|
