I Need your help
I have a board but i had got a problem "IMX6QP SabreSD"
Development environment:
1. IMX6QP SabreSD (Board)
2. imx-yocto-L4.14.98_2.0.0_ga (Linux)
3. LCD 480 x 272 @60p BGR16 (fb0)
4. HDMI 1920 x 1080 @60p RGB24 (fb1)
I had got a problem on dual display "fb0:LCD 480x272@60 BGR24 fb1:HDMI 1920x1080@60 RGB24"
LCD output(picture) is "OK" but doesn't output of a HDMI
