    I'm trying to enable the s-video out on the 3530 torpedo dev kit using the following boot args:

    omapfb.mode=tv:ntsc omapfb.debug=y omapdss.def_disp=tv omapdss.debug=y

    But the omapfb support fails with:

    [ 366.637756] OMAPFB: omapfb_init
    [ 366.641021] OMAPFB: omapfb_probe
    [ 366.644287] omapfb omapfb: no displays
    [ 366.648101] OMAPFB: free_resources
    [ 366.651519] OMAPFB: free all fbmem
    [ 366.654968] omapfb omapfb: failed to setup omapfb
    [ 366.659729] omapfb: probe of omapfb failed with error -22

    From my extremely limited knowledge of the DSS system, it seems like the s-video out needs to be set up in the board-specific kernel file: board-omap3logic.c, but that only seems to define the LCD. Does anyone have any insight into this problem?

    [I know this is old, but might be useful.]

    I enable COMPOSITE in the Linux Kernel config.

    from the command line where your linux kernel sources are located...

    make menuconfig

    should bring up the Linux Kernel configuration menu system
    use / to search for COMPOSITE
    enable it
    build kernel
