[JdeRobot] Mk802IV with Jderobot

[Jose Antonio Fernandez]

Hi,

I'm installing Ice in the same device but apply the patch you say Jderobot
compile but cameraserver gives this error:

VIDIOC_DQBUF: Invalid argument
libv4l2: error dequeuing buf: Invalid argument

I suppose that this patch is not enough at least to cameraserver

But Andres if you takes a different result applying this patch please say
to me because I've installed too a cross compiled of Ice to armhf so It's
ok or not.

Thanks
