Subject: problem with directfb example
To: [email protected]
hi. all
my target board is beagleboard.
I have cross-compiled directfb for beagleboard. but when I test the
examples in directfb-examples, some can be run without error, but the
others will failed.
please help me to figure out what's the problem it is. is it the
error about framebuffer arguments, or is it the error about lacking of
HW acceleration driver?
Where is the HW acceleration driver error?
Did I overlook it?
I mean the directfb don't have the HW driver acceleration for
beagleboard, is that right? ( please see the error details pasted
below)
If there is no correct HW driver you can always try the argument
"--dfb:no-hardware" to see if that works.

the "signal 11" (segmentation fault) is fatal, it would be interesting
if you had a backtrace of that.
Also, the panning failing is due to the fact that it cannot reserve a
sufficiently large buffer; check your FB driver in the kernel, or retry
with a lower resolution first to see if that works (like VGA 640x480 is
a good choice). You might try df_dok which is less memory hungry than
df_andi.
