How to use composite video out of OLinuXino?

Postby ivanovp » Thu Jan 30, 2014 6:57 pm

Is video out supported in linux-armv5 3.2.18 kernel or in linux-olinuxino 3.7.2?
I've got backup of older ArchLinuxARM root directory and it contains oli-2.6.35-8-ARCH+-pal.sb in /boot. I think that it worked for me with XFree86 a year ago. How can I get the uImage/zImage from this .sb file? I had no luck to put it to the /dev/sdX1 and boot. Tried these commands:
sudo dcfldd if=/somewhere/boot/oli-2.6.35-8-ARCH+-pal.sb of=/dev/sdb1 ibs=512 seek=4 conv=sync,notrunc
and without seek
sudo dcfldd if=/somewhere/boot/oli-2.6.35-8-ARCH+-pal.sb of=/dev/sdb1

I figured out what I missed. Zeroes should be before the .sb image.
Generate zeroes, then append the .sb:
dd if=/dev/zero of=oli-2.6.35-8-ARCH+-pal.img bs=512 count=4
dd if=oli-2.6.35-8-ARCH+-pal.sb of=oli-2.6.35-8-ARCH+-pal.img ibs=512 seek=4 conv=sync,notrunc
dd if=oli-2.6.35-8-ARCH+-pal.img of=/dev/sdX1
