Hello, I connected an HDMI monitor to beagleboard but the video
flickers (I can see there is a login screen of xubuntu shown but it
oscilates). I think it is because the default beagleboard mode is not
supported by the monitor.
Can I manually modify boot.src to change the video mode?
Can I change the video mode on-the-fly
Thanks
In u-boot you can set resolutions by:
setenv dvimode 1280x720MR-16@60
or any other resolutions, supported by your display

That would work if he wasn't using a boot.scr script.... The default
boot.scr people use for ubuntu specifies it's own resolution and
ignores the u-boot variable...
And how to setup after boot time and without a serial cable and no PC access ?

Since it's april 1st, i was thinking buttefly's... http://xkcd.com/378/
mount the fat partition on a booted beagleboard and edit the file..
rerun mkimage on the beagle, unmount and reboot...
Regards,
Sorry, you can't actually edit the boot.scr directly....
create a boot.cmd similar to boot.scr but without all the extra header
junk for u-boot..
like: http://elinux.org/BeagleBoardUbuntu#Create_U-Boot_boot_image
then run..
mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Ubuntu 9.10"
-d ./boot.cmd ./boot.scr
Of course this assumes mkimage is installed on your beagle, if not
then you'd have to use a regular x86 with mkimage pc to create it...
(sudo apt-get install uboot-mkimage)
Regards,
Thanks for clarifying.
