no displayoutput

[ChrisVonFrosta]

with official raspberry 7" display no output.
touch is working.
Display output works until i start programm.
I tried with both, main.c and buttonExample.c

[mwilliams03]

these default to use framebuffer 1. And the official display comes up as frame buffer 0
in framebuffer.c change
char *fbdevice = "/dev/fb1" ;
to
char *fbdevice = "/dev/fb0" ;

then recompile.

hi...
first the program was canceling with "memory access error". Then i red this. With the change to < char *fbdevice = "/dev/fb0" > the programm runs, but just with touch and without display output.

I tried both, main.c and buttonExample.c

Using Jessie lite and the official 7" display.
Thx!
