Beaglebone Black and LCD7 Cape not Working

[wisar]

I just loaded my Beaglebone Black with Archlinux and things are working well...except that the LCD drivers don't seem to load at startup. From looking at the board it appears that others have had success where I am only getting a blank screen. Here is the relevant part of the DMESG traffic:

As stated the file BB-BONE-LCD7-01-00A3.dtbo was not in /lib/firmware. I don't really want to have to dig deeply into device trees so am hoping someone can short cut me! I did try moving the LCD7 files from a working Angtrom OS onto the Arch instance but that gave me the following:

Any Christmas help would be appreciated!

Never mind on the above...

pacman -S linux-am33x-legacy

Rolled back to older kernel and BANG I have a working LCD. Touchscreen 'seems' to be working far better than under Debian or Angstrom as well.

Happy New Year,
Will
