.. _openAMP_rsc_table_sample: 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 ***** Booting Zephyr OS v#.##.#-####-g########## ***** Starting application thread!
