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,
Thanks Steve T
