Hi All,
As I have to port INTEL broad which include Display driver and
DirectFB driver. As in the Intel architecture, DirectFB module is top
of display driver and graphic driver. I have to write HAL for the ATSC
middleware. Related to this I would like to ask you few query on
this, would you help me out,
There are couple of query :
1. DirectFB API can be used for the implementation of HAL layer :
2. Can we use DirectFBAPI for the Implementation of HAL Layer and
Give example for basic implementation of Direct API
3. DirectFB Dirver is depend on the Display driver.. ...as my
understanding that ..Display driver is installed , configure and top
of this I would able to used DirectFB API.
Thanks,
Madhukumar.

DFBCHECK (primary->Flip (primary, NULL, 0));
sleep (5);
primary->Release( primary );
dfb->Release( dfb );
return 23;
}
Program is crashing on DFBCHECK (DirectFBCreate (&dfb));

Hello,
For cross compilation, I am doing following steps
1) configure
./configure CC=arm_v5t_le-gcc
LDFLAGS="-L/opt/mv_pro_5.0/montavista/pro/devkit/arm/v5t_le/target/lib/"
CFLAGS="-I/opt/mv_pro_5.0/montavista/pro/devkit/arm/v5t_le/include/"

--with-inputdrivers=none --enable-fbdev=yes --enable-png=no
--enable-freetype=no --enable-jpeg=no
where, /home/Harris/workdir/filesys is out target file system.
2) make ; make install
I have also checked putting data on /dev/fb0 [echo
"aaaaaaaaaaaaaaaaaaaa" >/dev/fb0]
I am able to see the data after wrinting on int. [cat /dev/fb0]
Please Help...!!!
