WebCam for BeagleBoard

HI I want to develop an application on Android with web cams. I have
checked this video

http://www.youtube.com/watch?v=L7LfVTv02cg

so it seems possible.

I want to know

which web cams are supported for beagleboard kernel ?

I have a Logitech Webcam C300 webcam and it is suported for linux V4L2
is this right ?

I am using the rowboat android Eclair, it works fine :slight_smile:

Thanks for all your help

Sincerely yours

Victor Rodriguez

Hello,

        Any camera that supports uvc should work but the camera module
for Android is a bit beta on the beagleboard. If you don't want to be
bleeding edge you would be better going for Ubuntu IMHO - that worked
out of the box for me.

Cheers,

Neil

Hello,

        Search google for "Ubuntu Beagleboard" and you'll find the
Beagleboard/Ubuntu wiki which is really good. I don't really
understand the source code question - sorry.

Thanks sorry for do not google first

About the kernel question is

Where can I get the kernel for beagle board with complete and current
support, for example for hawk board the complete kernel can be
downloaded from http://elinux.org/Hawkboard and from git.kernel.org
the initial support from
http://git.kernel.org/?p=linux/kernel/git/khilman/linux-davinci.git;a=summary

But is there any repository where I can get the latest and stable kernel ?

Thanks that is the one that I have clone and then i change to
remotes/origin/omap-2.6.32 branch

There I have found

omap3_beagle_defconfig

so I have done this

make -j5 ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- omap3_beagle_defconfig
make -j5 ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- uImage

BUt seems to have a problem with USB

In file included from drivers/usb/host/ehci-hcd.c:1114:
drivers/usb/host/ehci-omap.c:40: fatal error: mach/usb.h: No such file
or directory
compilation terminated.
make[3]: *** [drivers/usb/host/ehci-hcd.o] Error 1
make[3]: *** Waiting for unfinished jobs....

Is this the correct branch and defconfig ?

That is the correct error you'd get for the branch and defconfig you
specificly 'chose'

Either use an external patch to fix that issue, or use a much later
and stable checkout, such as the current 2.6.37-rc2 master.. (with the
omap2plus_defconfig)

Sorry, there also was a serial change with 2.6.37 use "ttyO2" as in O
for 'O'map vs the old 'ttyS2'

HI it seems that the problem is with the Angstrom File Systems I have
tested with ALSA File System from source code BeageBoard and works
fine, does any body know the reason ?

Thanks and regards
