Beagleboard-xm s-video output

[ayunus]

How can I use the s-video output of the beagleborad that has Ubuntu
10.10 release ? I editted the bootargs as omapfb.mode=tv:ntsc
omapdss.def_disp=tv

But no change. The display opens again through DVI-D port

U might propably have edited the boot.cmd
Actually U-Boot reads from boot.scr

So, delete the old boot.scr and  use the following command to generate boot.scr reading the contents from boot.cmd

mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Ubuntu" -d ./boot.cmd ./boot.scr

I have editted /boot/boot.scr file
when I use your suggestion I get error notexisting boot.cmd

[ahmet bay]

I have followed these steps to edit boot scr. bootargs has changed on boot.script but no diiference on ports

https://wiki.ubuntu.com/ARM/BeagleEditBootscr

bootargs has changed on boot.script and created a new boot.scr  but no diiference on ports  it starts through the HDMI port

[ayunus]

What is the exact solution way to change default display mode, from
dvi to tv ?
Maybe I did some misteakes

These settings usually work:

Then however your doing it isn't correctly sending the info to the kernel..

please copy your complete serial log from power on... to pastebin.com
and we can take a look at that..

[ahmet bay]

Because the bootargs doesnot change these are only visible I added omapfb.debug=y but no change. I also added printenv output and the /boot/boot.script file

Try also adding "console=tty0" after "console=ttyS2,115200n8" in the
bootarg ubuntu's kernel might be ignoring your setting and defaulting
to dvi..

[ahmet bay]

Nothing changed  but I noticed that the output of the mkimage is ;

mkimage -A arm -O linux -T script -C none -n "Ubuntu boot script" -d boot.script boot.scr
Image Name:   Ubuntu boot script
Created:      Wed Mar 30 17:16:56 2011
Image Type:   ARM Linux Script (uncompressed)
Data Size:    326 Bytes = 0.32 kB = 0.00 MB
Load Address: 0x00000000
Entry Point:  0x00000000
Contents:
   Image 0:      318 Bytes =    0 kB = 0 MB

is it normal for Load address 0x00000 and other parameters ?

[Robert Nelson]

Yeap, it's just a script so no load address's would be needed..

Weird, so maybe they are missing something in their 2.6.35 kernel..

I have tried to edit user.scr in the xm Test SD Card that shipped with BB. But I could not use s-video port on it. I think I am missing some step but which one ?

I'm not sure about the verison on teh test sd card..

But i know my demo image works: http://elinux.org/BeagleBoardUbuntu#Demo_Image

Flash your sd card, then boot it once with dvi..

goto: /boot/uboot/

open boot.cmd: sudo nano boot.cmd

change it to s-video.

run: ./tools/update_boot_files.sh

reboot..

or just wait about 48 hours, i'm pushing a new release based on ubuntu
natty's beta, and it'll also use the new "uEnv.txt" boot method..
(text editable script, vs using mkimage's boot.scr)..

[ahmet bay]

And also I dont have a boot.cmd file on the file system

Yeah, that's only with my images..

[ahmet bay]

I had your demo image on another sd card. Now I amtrying to follow steps I have open boot.cmd with nano but to add s-video will I change

setenv dvimode .... line  with the lines 
setenv omapfb.mode tv:ntsc
setenv omapdss.def tv

??

[Robert Nelson]

i wouldn't worry about the individual variables, just change the bootarg line:

"omapfb.mode=tv:ntsc omapdss.def_disp=tv"

[ahmet bay]

Yeah it works :))
 Problem in the .35 kernel
Thanks for your help
Best Regards

[ahmet bay]

Is it works if I use your boot.scr for s-video working on .35 kernel ? Does any problem occur ?
And I want to ask if I copied all files in a booting  SD Card to another truely formatted  SD Card directly, Is ıt works or I have to do every thing scratch from ?

It'll probally work, but the it uses a different omap serial driver..
(ttyO2 vs ttyS2) (changed in 2.6.36)

Yes/No... the rootfs can be copied as is to any media, mmc/usb
disk/etc as long as it's a normal linux partition.. the bootloader
files (mlo/u-boot.bin) need a perfectly created fat16 file system..

[ahmet bay]

Again I have a problem about s-video

for 2.6.38 kernel I editted the bootargs to run s-video output. It works for start boot steps,it gives s-video output , when it tries to appear the login  screen , s-video output is off so I can not see the gnome neither s-video nor DVI. With serial port I have logged in and tried to run a gui application and got this error

Error: Unable to initialize gtk, is DISPLAY set properly?

how can I initialize gtk  on s-video ?

[ayunus]

I have solved this problem with installing xserver-xorg-video-omap3
