To fix LCD problem:
Download DirectFB patches (click here).
Copy patches and kernel spec to LTIB:
tar zxvf DirectFB-patches-specs.tar.gz
cd specs
cp kernel-imx31_3stack-2.6.24-DirectFB-LCD-fix.patch /opt/freescale/pkgs/
cp kernel.spec.in ~/ltib-imx31pdk-r14/config/platform/imx/
Remove old kernel:
~/ltib-imx31pdk-r14$ rm -rf rpm/BUILD/linux*
Issue LTIB to decompress kernel and apply patches:
~/ltib-imx31pdk-r14$ ./ltib -p kernel -m prep
You will see at end:
+ echo Patch #1 (kernel-imx31_3stack-2.6.24-DirectFB-LCD-fix.patch):
Patch #1 (kernel-imx31_3stack-2.6.24-DirectFB-LCD-fix.patch):
+ patch -p1 -s
+ exit 0
Build time for kernel: 21 seconds
It means which kernel-imx31_3stack-2.6.24-DirectFB-LCD-fix.patch was applied correctly!
Now compile your kernel:
~/ltib-imx31pdk-r14$ ./ltib -p kernel -m scbuild
Install it on your rootfs:
~/ltib-imx31pdk-r14$ ./ltib -p kernel -m scdeploy
To fix Touch-Screen
Copy specs to LTIB:
cd specs
cp tslib.spec ~/ltib-imx31pdk-r14/dist/lfs-5.1/tslib/
cp DirectFB.spec ~/ltib-imx31pdk-r14/dist/lfs-5.1/DirectFB/
Remove old directories:
~/ltib-imx31pdk-r14$ rm -rf rpm/BUILD/tslib-1.0/
~/ltib-imx31pdk-r14$ rm -rf rpm/BUILD/DirectFB-1.1.0/
Edit your pkg_map and change tslib order. DirectFB needs tslib, then this lib needs be compiled first:
[alan@localhost ltib-imx31pdk-r14]$ vi config/userspace/pkg_map
...
PKG_TSLIB = tslib
PKG_DIRECTFB = DirectFB
PKG_DIRECTFB_EXAMPLES = DirectFB-examples
...
Now run:
alan@armagedon:~/ltib-imx31pdk-r14$ ./ltib -c
Then select DirectFB and tslib packages.
To test Touch-Screen
mx31# mknod /dev/input/tslib0 c 13 65
mx31# export TSLIB_TSDEVICE=/dev/input/tslib0
mx31# rm -f /etc/pointercal mx31# ts_calibrate
mx31# df_window
