Hi,
I am using Qt embedded 4.5 on a Sigma SMP Mips target board and continue to get this error when running any Qt demo:
tango3[books]# ./books -qws -mouse -keyboard
QScreenLinuxFb::connect: No such device
Error opening framebuffer device /dev/fb0
: driver cannot connect
Aborted
tango3[books]# ls -l /dev/fb0
crw-r--r-- 1 root root 29, 0 Dec 31 16:00 /dev/fb0
Any help is MUCH appreciated.
It appears that the open("/dev/fb0",O_RDWR) call is failing but I need more info to debug.
I tested my directfb build using dfb's demos and it appears to be working.
Anything related to linux image build? some build option left out?
