BBBW wlan0 testing

[Kevin Gordon]

I have been trying to resolve what causes a successful setup of connman to fail in Beaglebone Black Wireless. These are the steps:

(1) Make a SDcard using bone-debian-8.7-lxqt-4gb-armhf-2017-02-12-4gb (successful)

(2) Use connmamctl to setup wlan0 (successful)

(3) #apt-get update #apt-get install leafpad #apt-get install gdbserver (successful)

(4) #nano /boot/uEnv.txt (remove # from "dtb=am335x-boneblack-emmc-overlay.dtb")

(5) reboot

(5) #ifconfig -a (HEY wlan0 has disappeared and eth0 is now present with no internet)

(6) #nano /boot/uEnv.txt (replace # in front of "dtb=am335x-boneblack-emmc-overlay.dtb")

(7) #reboot

(8) #ifconfig -a (HEY wlan0 has appeared and eth0 reappeared with internet working!)

@RobertCNelson please help!

Extra item (9) #shutdown no longer is successful. BBBW immediately self reboots......

So, due to the shear number of *.dtb files, i haven't implemented a
direct "emmc-overlay" specific for the bbbw.

Instead, i've implemented something newer, utilizing U-Boot overlays.

First check what version of U-Boot you have installed via:

debian@test-bbb-1:~$ cd /opt/scripts/
debian@test-bbb-1:/opt/scripts$ git pull

Next take a look at this document:

http://elinux.org/Beagleboard:BeagleBone_Debian_Image_Migration#U-Boot_Overlays

to implement "dtb=am335x-boneblack-emmc-overlay.dtb" for the bbbw use
these options in /boot/uEnv.txt

enable_uboot_overlays=1
disable_uboot_overlay_video=1

(make sure you don't have a /uEnv.txt file as that isn't implemented
with this new method)
