Andrew:
Thank you for this post.  I have this image working on my BBB using 4D 
Systems 4DCAPE-43T Cape by editing the uEnv.txt as: video=480x272-16@56 .  
I am able to SSH to the device using Android SSH Server on the device and 
putty on my PC.  However, I need to know the root password for this image.  
I like to avoid using 'adb shell' to get to the root.  I really want to 
root this device.  I use Xamarin as a development tool and it works well.  
However, when I try to access, via code, the 
"/sys/class/leds/beaglebone:green:usr0"
to set the trigger to "none" I get Access Denied.  I need root access via 
my code...I am pulling my hair on that one.  any help is appreciated.
Kindly
Rich
