| OpenAMP Sample Application using resource table |
| ############################################### |
| |
| Overview |
| ******** |
| |
| This application demonstrates how to use OpenAMP with Zephyr based on a resource |
| table. It is designed to respond to the `Linux rpmsg client sample <https://elixir.bootlin.com/linux/latest/source/samples/rpmsg/rpmsg_client_sample.c>`_. |
| This sample implementation is compatible with platforms that embed |
| a Linux kernel OS on the main processor and a Zephyr application on |
| the co-processor. |
| |
| Building the application |
| ************************* |
| |
| Zephyr |
| ------- |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/subsys/ipc/openamp_rsc_table |
| :goals: test |
| |
| Linux |
| ------ |
| |
| Enable SAMPLE_RPMSG_CLIENT configuration to build and install |
| the rpmsg_client_sample.ko module on the target. |
| |
| Running the sample |
| ******************* |
| |
| Zephyr console |
| --------------- |
| |
| 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. |
| |
| Linux console |
| --------------- |
| |
| Open a Linux shell (minicom, ssh, etc.) and insert a module into the Linux Kernel |
| |
| .. code-block:: console |
| |
| root@linuxshell: insmod rpmsg_client_sample.ko |
| |
| Result on Zephyr console |
| ------------------------- |
| |
| The following message will appear on the corresponding Zephyr console: |
| |
| .. code-block:: console |
| |
