Hello,
how can I enable S-Video with the current "Angstrom-kernel"?

You can't.
Okay, thanks for the answer.

Hello all,
a additional question.
This was covered extensively on this list a few weeks ago and the
consensus was that the best way forward would be to add s-video
support to the new DSS lib (whether that will be the nokia one or the
TI one).
regards,
Koen
Okay, I see, Thank you. I will have a look at the archives.

I foudn the thread:
http://groups.google.com/group/beagleboard/browse_thread/thread/dc11612c4d6533cf/e6d794fbf2d0abea?lnk=gst&q=s-video#e6d794fbf2d0abea
Does someone tried the two patches with the latest kernel? Is it working?
Robert
JFTR. Yesterday I was poited to
http://www.bat.org/~tomba/git/linux-omap-dss.git/. This kernel should
have the latest patches to make s-video working. I tried it but:
Kernel command line: console=ttyS2,115200n8 root=/dev/mmcblk0p2
rootdelay=2 rootfstype=ext2 ro video
=omapfb:mode:1024x768@60 psplash=false
...
Console: colour dummy device 80x30
...
Unable to get DVI reset GPIO
OMAP DMA hardware revision 4.0
Missing LCD configuration
and a fuzzy display.

The omap3_beagle_defconfig in the git tree has not been modified (I guess
I should). So you need to enable the new DSS. Attached is my config, with
DSS enabled.
Note also that currently the S-Video output defaults to PAL mode, and
there's no dynamic way to change it. If you want NTSC, change from
arch/arm/plat-omap/dss/venc.c:venc_init()
int use_pal = 1;
to
int use_pal = 0;

Hello,
this is robert, the human gateway for Tomi Valkeinen.
how can I enable S-Video with the current "Angstrom-kernel"?
You can't.
I can.
1. Grab the recent kernel from http://www.bat.org/~tomba/git/linux-omap-dss.git/
2. git clone http://www.bat.org/~tomba/git/linux-omap-dss.git/ ; cd
linux-omap-dss; ....
2. Compile the kernel with the attached config (USB host is not
working so I cannot use my keyboard. But this should only be a little
change?)
3. Use this kernel 
This is directly from Tomi:
##################Tomi start##################
Yes, the current version doesn't parse any command line parameters.
You can change the default DVI resolution from kernel config, Device
Drivers/Graphics support/Omap2/3 display device drivers/
As for the USB, my kernel config enables usb gadget mode. I don't know
what kind of USB you need, so perhaps turn it off.
No framebuffer is by default directed to s-video. You have to
configure it from the sysfs interface. Check out
Documentation/arm/OMAP/DSS
For example, try this:

That's not "the current Angstrom kernel", that's Tomi's kernel.
# CONFIG_NEON is not set
So you gain TV-out, but loose all the fancy NEON stuff, e.g.
omapfbplay and mplayer will crash.

I don't see anything that would prevent him turning CONFIG_NEON back on.
I was pointing out that the magic defconfig disabled NEON so we won't
get a flood of "s-video works, but everything crashes" mails

Sorry, of course you are right. All I want to say is that it is
possible to use s-video with a kernel newer than 2.6.22.
Sorry again for beeing unclear.
