Hy,
I´m having a very similar problem. I am using the current version of ubuntu
for BBB (Ubuntu 14.04 LTS (GNU/Linux 3.8.13-bone47 armv7l)) and tried to a
device tree overlay with this guide for the exact same cape:
I'm looking into the same thing and running into the same problems of no
simple tutorials. At this point I'm having issues getting the PRU to even
be enabled, and I'm not really sure why.

Thanks for the pointer,
I'm rather confused. I cannot seem to disable BB-BONELT-HDMI using the
uEnv capemgr.disable_partno optargs arg.
My uEnv.txt line looks like this:

but:

I'm an idiot. I blindly followed instructions that were likely for
Angstrom, and put the dtb file in the wrong place, /boot instead of

Sorry, one minor correction.
The dtb file should be in one of the following places:
/boot
/boot/uboot/dtbs
If you're using the latest Debian image then it's the second. I believe
Angstrom uses the first. It looks like the Yona-Appletree LEDscape readme

If you're using Debian Wheezy, the instructions below are taken from my
blog and work. More information here: https://wiki.debian.org/LSBInitScripts
Create some file, and edit it accordingly. In my case *test*
*touch /etc/init.d/test nano /etc/init.d/test *
And in the file we put . . .

NOTE this method knows nothing about when your board has power applied.
This service*will* however start every time Debian is booted up. Even from
a soft boot / restart.
