You have two choice:
1.Enable SMP. STM32H767 has two different CPUs(Cortex-M4 and Cortex-M7),
but since Cortex-M7 is superset Cortex-M4, it may possible to build NuttX
with Cortex-M4 but run on Cortex-M7 too if Cortex-M7 has the same external
view as Cortex-M4 and give up Cortex-M7 specific feature(e.g. cache...).
2.Enable AMP. NuttX fully integrate OpenAMP recently:
https://github.com/OpenAMP/open-amp
And build many drivers or subsystem on top of OpenAMP, so you can use
usrsock+rpmsg to achieve what you are asking:
[image: RpmsgNET1.JPG]
[image: RpmsgNET2.JPG]
And more..., you can get the more information from this presentation:
https://cwiki.apache.org/confluence/display/NUTTX/NuttX+And+OpenAMP
NuttX even has a demo run two NuttX simulator on PC communicate with each
other through OpenAMP framework:
boards\sim\sim\sim\configs\rpproxy
boards\sim\sim\sim\configs\rpserver
You can follow the instruction in boards\sim\sim\sim\README.txt to try the
demo.
Since several patches are pending to merge:
https://github.com/OpenAMP/open-amp/pulls
You can't build the offical NuttX repo with OpenAMP directly. To simplify
the final user, I am preparing a new PR to download and apply these
patches. The work will upstream to NuttX repo in the next week. Please stay
tune the process.

Steelen & Ben,
With the below patch, you can try NuttX+OpenAMP in the simulator without
any special action:

Sure, I can provide some experience if needed.

I am interested in Open-Amp and maybe a Zoom webinar would be a nice idea?
I could start something?
