Hi All,
We have successfully loaded OMAP3/4 Maverick 10.10 Linux image to Beagle Board XM Rev B with SD card (4GB) as the boot source. For changing the display screen to a TV output with S-Video connectivity, we changed the bootargs for NTSC as per The S-video output is enabled by changing the bootargs at Uboot as given below. omapfb.mode=tv:ntsc omapdss.def_disp=tv The Bootargs are also validated in Boot.scr file as shown below. Setenv bootargs 'console=tty0 console=ttyS2,115200n8 root=/dev/mmcblk0p2 rootwait ro vram=12M omapfb.mode=tv:ntsc omapdss.def_disp=tv fixrtc buddy=unknown' With the above settings, we were able to see the display output on a S-Video enabled TV. However, around 10% of the left and right margins of the screen are out of display. The same S-Video (screen mis-alignment) problem was observed with PAL settings also. Any thoughts or pointers on how this issue could be fixed is highly appreciated. Regards, Ajish S , Embedded Design Engineer.
