S-Video on BeagleBoard-xM running ICS

Hello,

I am trying to use the S-Video output on the BB-xM with ICS 4.0.3.

I set all the boot parameters in boot.scr, have the video activated but no clear image on it. I tried also usign adb commands by switching the overlay and display from HDMI to SVideo. I can switch the S-Video on and off but the image is not there. Any help to sort this out?

Thank you,

Regards,

Enrico

    Hi Enrico,

    1. Are  you not getting image or are your getting blurred image screen ?

    2. is DVI port working fine ?

    3. Check the screen shot using DDMS , if it works fine then could be issue with mode switch

    Hi Enrico & Satish,

    Enrico:

    Did you update the configs file to compile with CONFIG_FB_OMAP2_FBS=2 ?

    Do you have the same problem if you set DVI resolution at 640x480 or 720x480 ?

    Enrico & Satish: Under TI's 4.0.3 pre-built binaries I am able to switch between S-Video and DVI as well as run S-Video and DVI simultaneously.

    A. I had to recompile with CONFIG_FB_OMAP2_FBS=2.

    B. This works if the 2 ports have the same resolution and scaling isn't needed. Since S-Video resolution is limited, I'm stuck with the same resolution for DVI.

    I encountered the second limitation search through the forum but, now can't locate the thread.

    Regards,
