Getting started with PRU (Trying to find examples)

There are a lot of examples for PRU in the web, but most of them don’t work correctly with latest images .

Most occuring problem - setting up tree overlay for pru.

Are there any examples or tutorials , which would work with 4.14 kernel , Debian 9.5 2018-08-30?

Hi,
I had the same problem last year so I created this small documentation: https://github.com/PierrickRauby/PRU-RPMsg-Setup-BeagleBoneBlack
It should work, if not, do not hesitate to tell me!

Sadly, ti changed the remoteproc driver in v4.14.x so a few ^ things
need to be changed..

Best thing, just make a note, "currently, this is for v4.9.x-ti
remoteproc_pruss"...

ps, TI's broken compatibly on every version so far. :wink:
v3.14.x/v4.1.x/v4.4.x/v4.9.x/v4.14.x...

Ok, will do!

That was also my felling… do you know why they keep breaking it ? That’s quite annoying …
