No clue, I built it for the rock64, on the rock64, useing the patches 
from the linux-rt mailing list links, but when I asked how to install 
it, 3 times  over about as many weeks, and got ignored, I gave up. Their 
propaganda says good support, but AFAIWC, there isn't any.  But the pi 
is only very marginally better.  Bulding an rt kernel on the pi is a 
several hour project, on the rock64 its about 30 minutes, which amply 
demo's the difference in speeds.  Too bad I cannot use it. Neither has 
any docs available to aid the hacker. Those are proprietary designs.  
Run the linux they supply, or go pound sand.

Take care now, E. Liddell.
