Using a iMx7 Sabre board and RGB888 works in UBoot but not linux.

Using a iMx7 Sabre board I have fitted an RGB888 display and adapted the connector to suit. UBoot works and displays the freecsale logo and a small amount of text onto the LCD display,


But Yocto / Linux does not. The display just goes black and nothing is displayed. If I plug and HDMI display in then Linux displays the GUI on the Monitor correctly.  The LCD remains blank.


What have I missed, I have readd many docs but I am struggling to understand what the problem is.


I  would appreciate help,
