• Yes, this is possible. In the device tree, e.g. armstonea9q.dts, you have the following setting:


    Code
    1. /*
    2. * Define this for a two-channel display, i.e. one display, one framebuffer,
    3. * but two LVDS channels, even pixels from one channel, odd pixels from the
    4. * other channel. Only define either DISPLAY_LVDS0 or DISPLAY_LVDS1 in this
    5. * case, using the full display resolution.
    6. */
    7. //#define CONFIG_ARMSTONEA9_LVDS_SPLIT_MODE

    So just uncomment the define and then set the full resolution in your LVDS0 timings entry. That's it.

  • OK, thanks. We will try.

    Another question for creating the cable is: What channel is for odd pixels, what is for even pixels?

    If we make a 1:1 cable, channel 0 will be odd and channel 1 will be even pixels (I would expect it the other way).

    Who can tell us?

    Thanks

  • As far as I know, pixels are counted from zero, i.e. starting with an even pixel. Even pixels should be on LVDS channel 0 then, odd pixels on LVDS channel 1. If the result is still showing swapped channels at the end, I believe you can fix this by using LVDS1 as display device instead of LVDS0. Then the even and odd pixels should be swapped, too.
