No video output on overo with tobi

[flyguyjm]

Is it possible to enable video output on an overo with a tobi expansion board? As far as I can tell, bootargs is missing setting up and configuring a frame buffer and when I add the args that Angstrom uses (also from looking at the omap docs), nothing happens. My bootcmd file for creating boot.cmd is:

$this->bbcode_second_pass_code('', '
setenv bootargs 'console=ttyO2,115200n8 vram=12M omapfb.mode=dvi:1024x768MR-16@60 omapfb.debug=y omapdss.def_disp=dvi root=/dev/mmcblk0p2 rw rootfstype=ext3 rootwait'
mmc init
fatload mmc 0:1 0x80300000 uImage
bootm 0x80300000
boot
')
