pandaboard video output

[Jon <jdisnard@xxxxxxxxx>]

Hello.


Problem statement:
Fedora 17.
Updating to recent kernel on Pandaboard ES causes HDMI to stop working.
The known good setup is the stock panda-xfce image[1] on the
fedora-arm wiki [2].
There are some kernel parameters to mess with the video output, HDMI
or DVI-D at omapedia [3], but those do not help.
Here is what I tried in /boot/uboot/uEnv.txt:
omapfb.mode=dvi:1280x1024MR-24@60 omapdss.def_disp=dvi



Steps to reproduce:
yum --nogpgcheck install
http://dmarlin.fedorapeople.org/packages/FedoraArm/RPMS/noarch/xpfa-17-1.1.noarch.rpm
yum update grubby
yum update kernel-omap
...


Work-around:
go back to the old kernel.

cd /boot/uboot
cp uImage-3.4.2-3.fc17.armv7hl.omap uImage-omap
cp uInitrd-3.4.2-3.fc17.armv7hl.omap uInitrd-omap
[reboot]
