Hi,
can somebody please tell me the magic: how to get HDMI working on the Wandboard Quad?
First I just followed the installation-guide on http://archlinuxarm.org/platforms/armv7 ... /wandboard
..then tried different settings in /boot/uEnv.txt which I found on severel guides and google threads like:
"video=HDMI-A-1:1920x1080@60"
or
"video=mxcfb0:dev=hdmi,1920x1080M@60
fbmem=24M,10M"
I also tried building a new u-boot img (*described at http://www.eewiki.net/display/linuxonarm/Wandboard)...
but there is still no signal on my monitor which is connected with a HDMI-DVI cable (1920x1080@60 is the recommended resolution when connected to my desktop pc)
My first major step forward was running another u-boot img and new kernel as described in the eewiki guide, which gave me a black screen with some Tux penguins, but on the serial terminal I had some kernel panic stoping arch arm to run
edit: well all seems to work with the debian or ubuntu versions mentioned on the eewiki guide but how to install Arch with new Kernel and u-boot img?
edit2: seems I was to muddle-headed to install Arch properly.. if you dont follow the archarm guide it could work:
1.) Follow all steps in eewiki guide until "Copy Root File System" (use wget http://archlinuxarm.org/os/ArchLinuxARM ... est.tar.gz instead of the debian/ubuntu rootfs)
2.)

Together with Xserver stuff & xf86-video-fbdev I was able to start Xfce, unfortunately resolution is limited to 1024x768
