Have you followed http://elinux.org/BeagleBoard/video ?

But CONFIG_FB_OMAP_CONSISTENT_DMA_SIZE=6 does not seem to be enough. Set it as 8

Jesslyn

iappi · January 12, 2009, 7:37am

No, I didn't see that guide.
This evening I'll try.
Thank you very much!

By default only /dev/fb0 exists in the ram disk image. You have to create /dev/fb1 manually. Try:

mknod /dev/fb1 c 29 1

then run omapfbplay again. Perhaps this could be included in the next test image so this question goes away.

The udev cache is getting in the way, rm /etc/dev.tar to invalidate it.

I've done all, but omapfbplay doesn't work using.

So I try

setenv bootargs 'console=ttyS2,115200n8 console=tty0 root=/dev/
mmcblk0p2 rootwait rootfstype=ext3 video=omapfb:mode:720p60:vram:
2M,vram:4M'

but I have strange behaviour of screen, not in sync.

I use the upstream kernel and I have to modify the kernel sources for
the specific mode that I want to use. Not user friendly at all, but it
works

iappi · January 14, 2009, 4:24pm

upstream kernel

2.6.27 or 2.6.28 ?

which is its git hash ?

iappi · January 14, 2009, 4:35pm

With linux compile with OE today.

setenv bootargs 'console=ttyS2,115200n8 console=tty0 root=/dev/
mmcblk0p2 rootwait rootfstype=ext3 video=omapfb:mode:720p60,vram:
2M,vram:4M'

It works!!
How can I get the kernel hash?
