Stuck on waiting for root device... (7 replies)

Finally got around to gaining SSH using serial method. All seemed to go well.

Used "Updated 24 Feb 2015" @ http://forum.doozan.com/read.php?2,12096 to create on SD card.

Looking at serial console everything seems to go good until:

Begin: Waiting for root file system ... done.
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/mmcblk0p1 does not exist.  Dropping to a shell!

Any input on solution greatly appreciated.
