The link I gave you if for the 8.3 lxqt image.. Actually take a look at the example.sh
You'll probably need to rebuild the bb.org-overlays repo but that's explained in the eadme.MD..

The problem is, I have an older Rev B device that is running the image debian-8.3-ixqt and the device tree is slightly different. I followed a couple of examples and I couldn't get it to work so I figured I needed to understand how the mechanism works because eventually I need to turn on and off some devices via a transistor and just copying something from the web doesn't tell me what each section of the device tree does. and how the two versions, different capemgr locations, are different. > > The last example i tried suggested i put the dtbo in /boot/uEnv.txt and now the bone won't boot, all four led's stay lit so I feel it is time to stop counting on guess work and hope that what someone writes in a blog somewhere actually has worked on a recent image and figure out what I am doing. > > Thanks for all of your help. > > On Saturday, March 5, 2016 at 6:46:27 PM UTC-8, William Hermans wrote: >> >> In addition to what Robert has shown you there . . . the internet is literally littered with guides, blogs, and random ramblings on getting the ds18x20 devices working on both the Beaglebone's, and the rPI . . .

I have a beaglebone rev c that uses the capemgr device tree mechanism and I know how to make that work. I can't seem to find any reference that will get me started with the no capemgr device tree implementation. >>> > >>> > Can someone point me to a place that will help me figure this out?
