Hi,

I am trying to get the mt9p031 working from nand with a ubifs file
system and I am having a few problems.

/dev/media0 is not present unless I run:
#mknod /dev/media0 c 251 0
#chown root:video /dev/media0

#media-ctl -p
Enumerating entities
media_open: Unable to enumerate entities for device /dev/media0
(Inappropriate ioctl for device)

With the same rig/files it works fine running from EXT4 on an SD card.
Any idea why this does not work on nand with ubifs?

Is the OMAP3 ISP driver loaded ? Has it probed the device successfully ? Check 
the kernel log for OMAP3 ISP-related messages.
