Hi,
I wanted to attach a TFT screen to my Beaglebone Black, and followed the steps in this howto: http://www.element14.com/community/servlet/JiveServlet/previewBody/65082-102-5-294046/BB%20VIEW%20User%20Manual%20V3.pdf
Basically:
$ cp -f /media/udisk/zImage /boot/uboot
$ cp -f /media/udisk/*.dtb /boot/uboot/dtbs
$ tar -xvf /media/udisk/kernel_modules.tar.gzvcd -C /
$ cp -f /media/udisk/xorg.conf /etc/X11/ $ sync
Now, the device stopped booting. When attaching a serial cable to the debug header, I see:
Kernel image @ 0x82000000 [ 0x000000 - 0x424dc0 ]
Flattened Device Tree blob at 88000000
Booting using the fdt blob at 0x88000000
Using Device Tree in place at 88000000, end 88008cf5
Starting kernel …
Uncompressing Linux… done, booting the kernel.

Gave up waiting for root device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait long enough?)
- Check root= (did the system wait for the right device?)
- Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/disk/by-uuid/500d169b-f341-4504-91cc-36d9ddc6e362 does not exist. Dropping to a shell!

How can I fix this boot problem?
Thank you!
