Your intuition seems to be very good. After much testing, I now can see
that as soon as I enable "dtb=am335x-boneblack-emmc-overlay.dtb" and
reboot, the system does come up but wlan0 is no longer known. By that I
mean that "ifconfig -a" and "connmanctl technologies" both fail to list it.

Hello William, thank you for the prompt response. First of all, I have to
say that I have very little experience with the device tree, although I did
use dtb-rebuilder to enable SPI back in the linux v3.8 days. So, my first
request is: please point me to documentation that is current and helpful
When I uncomment "#dtb=am335x-boneblack-emmc-overlay.dtb" and add a line
for BB-SPIDEV1 as follows:
#Docs: http://elinux.org/Beagleboard:U-boot_partitioning_layout_2.0
uname_r=4.4.38-bone-rt-r14
###uuid=
#dtb=
##BeagleBone Black/Green dtb's for v4.1.x (BeagleBone White just works..)
##BeagleBo
While trying to update one of my boards, I received the following error:
root@test1:/opt/scripts/tools# uname -a
Linux test1 4.4.13-bone-rt-r11 #1 PREEMPT RT Sat Jun 11 08:59:59 UTC 2016
armv7l GNU/Linux
root@test1:/opt/scripts/tools# ./update_kernel.sh --bone-rt-kernel --lts-4_4
./update_kern
Sorry, false alarm. Somebody :-( had the wrong base dtb enabled. Once we
had "dtb=am335x-boneblack-emmc-overlay.dtb" enabled, it worked. I apologize
for the noise.

I'm working on a project that needs quite a few gpio's and we initially
chose to use the lcd pins on P8 because we are running headless.
Currently, we are running: Linux beaglebone 4.1.17-bone-rt-r18 #1 Mon Feb 1

I have had wireless working on a 3.8 BBB for quite some time and I wanted
to move to a v4 kernel in the hope that the "lagginess" of the wifi
connection would be reduced. I loaded another board with the LTS RT v4
kernel, did apt-get install wireless-tools wireless-regdb crda, and put my

Robert, I have the same question about the source of DTC 1.4.1-gXYZXYZXYZ -
I installed the device-tree-overlay package into a new build (Linux

GNU/Linux) and checked the version of dtc. It was v1.4.0. I tried running

Hello, I need to address six devices on a single spi bus, and I'm hoping to
avoid writing a device driver :-)
We will be updating from 3.8.13-bone68 as soon as there is a stable release
of a newer kernel. So far, my research hasn't turned up any indication that
spidev can support the use of add
