Hi. Thanks for the info in this thread.
I am also trying to get directfb running.
I can configure it, compile it, and install it.
But it always says that there is no system found when i try to run it.
As in:
# dfbinfo
--dfb:system=devmem,video-phys=0x83000000,video-length=691200,accelerator=6400
~~~~~~~~~~~~~~~~~~~~~~~~~~| DirectFB 1.2.3 |~~~~~~~~~~~~~~~~~~~~~~~~~~
(c) 2001-2008 The world wide DirectFB Open Source Community
(c) 2000-2004 Convergence (integrated media) GmbH
----------------------------------------------------------------
(*) DirectFB/Core: Single Application Core. (2008-09-05 00:06)
(!) DirectFB/core/system: No system found!
(#) DirectFBError [DirectFBCreate() failed]: No (suitable) implementation
found!
~ #
I have also compiled c64x.ko, but I would be okay first just getting it to
run at all. The basic framebuffers are working at /dev/fb0 etc.
I am using kernel 2.6.22 on a custom board but it has dvevm software ported
to it (only v1.10 right now).
I have a directfbrc file at /etc (and several other places) on the target
but I don't think it gets parsed.
Any thoughts about getting the 'system' found? It should be there, it all
compiled and installed without error.
Thanks,
-mat
