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
