Hi,

I have compiled the android source code to omap4 blaze. I'm able to get the display of android bootup sequence & AFS using the HDMI interface. But I want the to display on the LCD interface also. can any one give the u-boot boot parameters to display on HDMI as well as LCD out parameters. so that when the HDMI is not connected it displays on the LCD interface.

Regards,

Sainath

    Hi Sainath,

    I tested this on my Blaze Board. Both displays work (in parallel) with 4AJ2.5 release.

    If you like you can try addind omapdss.def_disp=hdmi in your u-boot settings (in u-boot/include/configs/omap4430sdp.h) :
    #define CONFIG_BOOTARGS "console=ttyO2,115200n8 mem=456M@0x80000000 mem=512M@0xA0000000" \
                " init=/init vram=10M omapfb.vram=0:4M omapdss.def_disp=hdmi androidboot.console=ttyO2"

    This should make your HDMI the default display.

    Best Regards,
