FREERTOS on both CPU

[padov...@gmail.com]

I'm trying to run two freertos applications on both CPUs using a Zedboard and Zynq7000, using OpenAmp and RPMsg. How i can do it? Thanks in advance.

RPMsg in OpenAMP uses virtio, virtio has master and slave.
Master is to allocate the shared memory.

One of your core needs to be master and the other needs to be slave.

Master example:
https://github.com/OpenAMP/open-amp/blob/master/apps/examples/rpmsg_sample_echo/rpmsg-sample-ping.c

Slave example:
https://github.com/OpenAMP/open-amp/blob/master/apps/examples/rpmsg_sample_echo/rpmsg-sample-echo.c

https://github.com/OpenAMP/open-amp/blob/master/apps/machine/zynqmp_r5/platform_info.c
provides example on how to create shared buffers based on predefined shared memory.

Best Regards,
Wendy
