BeagleBoard-xM dvi Monitor problem

Hi,
I am using the HDMI output of the BB to connect the LCD monitor, but I
have a problem. I have installed Ubuntu 10.10 netbook on microSD card.
After restarted the board, not every time sometimes only, the screen
does not show up. When it occurs, I changed the microSD card with the
xmTest card that includes Angstrom demo files, and screen is O.K.
after boots, then I change the SD Card with my Ubuntu Netbook, at that
time screen comes.

at uboot printevn;

dvimode =1024x768MR-16@60
default display = dvi

Is there enyone who has same issue? Do you know how can I solve this ?

Thanks Best Regards

First you'll need to provide more info:

add "omapfb.debug=y" to your bootarg's and copy your full boot log
from the serial port to pastebin.com so we can see it..

On minicom only theese mesages are visible boot log - Pastebin.com
after compressing line I can not see anything for log

to add this line to bootarg is it enough writing only

#setenv bootargs omapfb.debug=y
#savenev

nope it's not...

"reading boot.scr"

It's using the boot.scr for boot, so your going to have to edit that..

add: console=ttyS2,115200n8 too.. (or ttyO2 if it's 2.6.36++)

PS.. Reread: https://wiki.ubuntu.com/ARM/OMAPMaverickInstall

You followed the note: "On Beagleboard xM rev A3 and B" right???

But my board is RevB,

You followed the note: “On Beagleboard xM rev A3 and B” right???

I am not sure but I remember that I did

I found a boot.script file in the file system /boot and it includes only ;

fatload mmc 0:1 0x80000000 uImage
fatload mmc 0:1 0x81600000 uInitrd
setenv bootargs quiet splash ro elevator=noop vram=12M omapfb.mode=dvi:1280x720MR-16@60 root=UUID=8555d495-322b-4dcc-b9c6-ddbe8c11f1b2 fixrtc
bootm 0x80000000 0x81600000

is it normal ?
Is this file to add a new option to bootargs ?

BeagleBoard-xM Rev B will report themselves as a Rev A,. This is normal.

There are B's with the A gpio setting's, no big deal..

That would explain the broken dvi... All boards after A3 (so
including the B) moved the dvi enable line.. Since Canonical/Ubuntu
can't upgrade a kernel after release, you need to use the fixed on
listed there.

That's the main reason i still push out my own demo images:
BeagleBoardUbuntu - eLinux.org (with newer kernel's..)

Yes, that's their normal boot settings.. It's fine when things work,
but useless for debugging.. :wink:
