Use the following settings for yocto linux device for the DT070BTFT:

Display Settings

static const struct fb_videomode custom_mode = {

                /* 1024x600 @ 60 Hz, 31.5 kHz hsync */

                NULL, 60, 1024, 600, 19512, 140, 160, 20, 12, 20, 3, 3,

                FB_VMODE_NONINTERLACED | FB_VMODE_ASPECT_16_9, FB_MODE_IS_VESA,

};

For board design, be sure to use the following LVDS layout recommendations for IMX6 from the IMX6DQ6SDLHDG.pdf

  • Follow standard high-speed differential routing rules for signal integrity.
  • Each differential pair should be length matched to ± 5 mils.
  • LVDS differential pairs should have a differential impedance of 100 ohm
  • Note that there are no pad control registers for the LVDS signals. So drive strength is not controllable through software.

  • The space between two adjacent differential pairs should be greater than or equal to twice the space between the two individual conductors.
  • The skew between LVDS pairs should be within the minimum recommendation (± 100 mil).
