During Embedded Linux Conference Europe 2011 I attended one very interesting presentation regarding new LCD bring-up procedures.
Among other nice things we were presented with extremely useful utility that may save a bunch of time while guessing what is wrong with this brand new LCD.
And this is fb-test utility.
Feel free to check it out from here http://www.elinux.org/images/0/09/Fb-test.c and then simply build it with your cross-toolchain of choise.
Then on target run it.
More on this you may find here http://www.elinux.org/Board_Bringup_Utilities
These are slides from ELCE http://elinux.org/images/d/d5/Elce-2011-anders.pdf
