Hi Bill,
looks like your communication between DirectFB and the fb driver is
going wrong.
This:
(!) Davinci/Driver: FBIO_GET_TIMING failed!
--> Invalid argument
means the kernel doesn't understand the FBIO_GET_TIMING ioctl, and even
worse, it thinks you provided a wrong argument.
I suggest to check if your kernel supports DaVinci (look for davincifb.c
or something like that), and if it does, make sure that the ioctl
interface is still matching gfxdrivers/davinci/davincifb.h.

Hi all, I've been off-and-on attempting to get directfb on the
davinci for a few months. I am not having very much luck. I am
configuring with: "./configure --enable-static
--with-inputdrivers=none --disable-fbdev --with-gfxdrivers=davinci
--disable-sysfs --disable-multi --disable-sdl --disable-x11
--disable-png --disable-jpeg --disable-freetype --disable-freetype2"
on the target. Upon running "./dfbinfo --dfb:video-phys=0x83000000
--dfb:video-length=691200 --dfb:system=davinci" I get:
dfbinfo --dfb:video-phys=0x83000000 --dfb:video-length=691200
--dfb:system=davinci

I am lost as what to do here to resolve the missing layer (which I
guess is the reason for the DirectFBError ultimately). Should I be
concerned about the FBIO_GET_TIMING failure? Is this a result of the
TI modification to the ioctls in 1.2 LSP? Any guidance would be
great. Thanks!
Bill
