 Hi Tobias,
 
 I used your boot.scr and it worked. I thought it was because I included
 Bananapi.bin so I removed it and tried again. It booted. So I removed
 console=fb part and than it stopped working. Actually, it may be working,
 but I get black screen and cannot see anything, as I described earlier.
 Instructions in wiki do not say I have to explicitly say console=fb, and I
 thought that was the default anyway? Also, I do remember experimenting with
 this line and some extra for screen resolution in uEnv.txt, but for some
 reason I believe the board would not read this file at all.
 All in all, NetBSD requires console=fb in boot.scr to continue showing the
 picture over HDMI.
 
 Thanks Tobias,
