I'm trying to get SGX driver support in my Rev B5 BeagleBoard but I'm
having just some minor issues. I've used bitbake to create an image
and inculded libgles support in my custom image. Built fine, no
errors. Upon bootup I notice this:

ERROR: Module omaplfb does not exist in /proc/modules
ERROR: Module pvrsrvkm does not exist in /proc/modules
eth0: link up, 100Mbps, full-duplex, lpa 0xCDE1
PVRSRV_PIXEL_FORMAT_RGB888
/dev/mem opened.

Unknown HZ value! (78) Assume 100.
/etc/rc5.d/S81cups: line 232: echo_success: not found
cups: started scheduler.
Starting GPE display manager: gpe-dm

Angstrom starts up but when I try to run any of the OGL ES demos they
fail. I did - dmesg | grep PVR and it showed the move to be RGB888
despite the fact that my bootargs in uboot are 1024x768x16.

U-Boot version is 1.3.3 and Kernel is 2.6.29-omap1

I consulted http://code.google.com/p/beagleboard/wiki/HowtoUseSGXunderAngstrom
as well. No dice.

Anybody!?

hi,

  try this bootargs, please.
       setenv bootargs 'console=ttyS2,115200n8 console=tty0
root=/dev/mmcblk0p2 rw rootfstype=ext3 rootwait
omapfb.mode=dvi:1440x900MR-16@60'

That's way too old, you need 2009.0rc

Is that's what causing the problems you think?

I'll rebuild U-Boot today and see if I can get it to boot off the
MMC. I've always had a little trouble with that. I suppose I could
just flash it.

omapfb.mode=dvi:1440x900MR-16@60 is what did it.

thank you.

this is newer bootargs for linux-omap kernel since the kernel DSS2
module had updated.

the purpose is told the kernel DSS2 module using 16 bit depth color for display.

Hope somebody can correct me if what I am wrong.
