Note1: If the board is Dual or Quad core, the device tree blob is imx6q-smarcfimx6.dtb. If the board is Dual Lite or Solo core, the device tree blob is imx6dl-smarcfimx6.dtb If you are using LVDS panel, replace the corresponding device tree file by the following. For WVGA (800x480) LVDS panel:
imx6q-smarcfimx6.dtb --> imx6q-smarcfimx6-wvga.dtb
imx6dl-smarcfimx6.dtb --> imx6dl-smarcfimx6-wvga.dtb For XGA (1024x768) LVDS panel:
imx6q-smarcfimx6.dtb --> imx6q-smarcfimx6-xga.dtb
imx6dl-smarcfimx6.dtb --> imx6dl-smarcfimx6-xga.dtb For WXGA (1366x768) LVDS panel:
imx6q-smarcfimx6.dtb --> imx6q-smarcfimx6-wxga.dtb
imx6dl-smarcfimx6.dtb --> imx6dl-smarcfimx6-wxga.dtb For 1080p (1920x1080) LVDS panel:
imx6q-smarcfimx6.dtb --> imx6q-smarcfimx6-1080p.dtb
imx6dl-smarcfimx6.dtb --> imx6dl-smarcfimx6-1080p.dtb |
