Hello,

I use linux-omap-psp-2.6.32 and have no /dev/video* files.
If I build the omap-vout driver as module, I get this message:
"omap_vout omap_vout: probed for an unknown device"
after an insmod.
The Beagleboard is a rev C4.

How do I get the v4l2 driver running?

Thanks in advance

Sandro

[Hiremath, Vaibhav] Please make sure that, you configure CONFIG_FB_OMAP2_NUM_FBS=1

This will allow V4L2 driver to create 2 instances for Video1 & Video2 respectively.

Also make sure that you have platform registration code inside "arch/arm/mach-omap2/devices.c" file, since the this part of code got enrolled into later kernel version (2.6.35 merge window)

Thanks,
Vaibhav

Hi Vaibhav,

I am new to linux and currently facing the same problem as Sandro in linux-
omap-psp. You mentioned the need to create platform register at "arch/arm/mach-
omap2/devices.c". May I know how should I do a platform register for a
TVP5147? Also, I couldnt find anything related to CONFIG_FB_OMAP2_NUM_FBS
on "arch/arm/mach-omap2/devices.c".

Hope to hear from you soon.

Mark
