If  follow the instructions from Quick Start Guide for i.MX54 QSB. It appears  that maybe the sync freq is not working. There is a column about 1/5 of the lcd width that has the lcd screen layered in it. I did test the lcd when I first received the kit and the lcd work fine out of the box. I am running same sd card that came with kit. Only change has been toset bootregs to setup lcd.

 

Any ideas.

Can you share full output of the boot process (u-boot and Linux kernel)? Also kernel command line you're using? Also what display are you using?

 

Kernel parameters change sometimes between two BSP releases, so make sure you're using correct parameters for your setup.
