Hi!
I'm bringing up a custom board with imx6q and 10" TFT display with LVDS interface. I boot only a kernel and see very strange picture at the display. Please have a look at the attached picture and share your thoughts about what can be wrong with my connection. I'm pretty sure that the SW part works well because I used this kernel with Wandboard and a similar display and it worked as expected. Moreover a PC display connected to HDMI works as expected. Now the board is custom and u-boot has different settings adapted to the new board.
The TFT Innolux N101ICG-L21 display connects to LVDS0, 3 lanes, 1280x800px, 18bits,.
