    Hi, i am using Kernel 3.14.28 and got 2 Full-HD Panels connected via HDMI and LVDS.
    I built a custom Yocto-OS without wayland or x11.
    Kernel Args: fbmem=24M video=mxcfb0:dev=ldb,LDB-1080P60,if=RGB24,bpp=32 video=mxcfb1:dev=hdmi,1920x1080M@60,bpp=32

    This brings up 2 independent framebuffers (/dev/fb0 & /dev/fb2). Is there any possibility to clone/mirror the output from /fb0 to /fb2 or vice versa?

    i can only find outdated stuff on the nxp forum.
