I want the CPU and R5 to communicate with each other, how can I do it?

Hi All:

I want the CPU and Cortex-R5 core to communicate with each other, how can I do it?

Hello, wxsrite:
For Orin, only SPE R5 is open for public use.
You can download Sensor Processing Engine Sources from Jetson Linux | NVIDIA Developer.
l4t-rt/rt-aux-cpu-demo-fsp/doc/ivc.md may provide more information.

Regarding to other R5 processors, they are only for internal use in L4T BSP.
Hope that helps.
