I started using this image of Ubuntu for beagelbone black from https://elinux.org/BeagleBoardUbuntu
From what I so far found out and confuse me a bit, is that in this image there is some new form of interaction with PRU unit on SOC.
Via some RemoteProc driver exposing PRU to user space.
I was used to before uio driver and enabling it it device tree. (based on a lot of guides)
And I cannot run my older code on this new image.
Could you please propose some example Dev Guides how to work with this new driver module?
Best would be some examples with Makefiles with sources directly on BBB.
And how to load PRU binary to PRU and interact with it.
I am really lost here now
