I've been running for about 1 year now on two RK3066's with USB webcams 24/7. I did have the disappearing USB device (gone from lsusb) until I played around with different kernels. Also different cameras were better such as http://www.amazon.com/Kinobo-Origami-Webcam-Desktop-microphone/dp/B004FLJ4YI which rarely disconnected even with Alok's kernel. The main reason I set out to build my own distribution and kernels is to have complete control over the OS and kernel.

I have the MK802IV quad core running Ubuntu 14.04 already and I'm in the process of documenting that. This will allow the possibility of inline people detection without affecting the the normal frame acquisition and motion detection flow. I'm working on a Java solution where I left off with my Python solution for a loosely coupled plugin based architecture for motion detection and frame processing. The core is already built out and can detect multiple areas of motion per frame and write videos. In my Install OpenCV project https://github.com/sgjava/install-opencv I provide example code for motion and people detection for Java and Python. It wouldn't be hard to use this with Motion to analyze videos.

Hi Steve,
I have MK808 and MK802IV so I'm kinda interested in your ubuntu-mini
My main goal is to run motion on those devices. So far my long-term tests on Rockchip devices constantly fail. Most issues are USB related: /dev/video0 disappears or fail to respond. Sometimes devie may die with out of memory killing essential processes like wpa_supplicant or irqbalancer.

I have also MK802II which is based on Alwinner A10 and it was running motion for almost 1 year (!!!) without interrupt. I only turned it off once to change power adapter. So I believe motion has great potential running on low power ARM.

If you need to perform some more testing - ping me I would be happy to assist

I've posted my Ubuntu Mini project on GitHub https://github.com/sgjava/ubuntu-mini that will let you build any version of Ubuntu on the RK3066 dual core ARM mini PCs. A lot of the ARM based distributions are not based on LTS versions of Ubuntu. I've tested Ubuntu 12.04 and Ubuntu 14.04. Rolling your own lets you know exactly what's in the distribution.

I've included instructions of how to build various kernels or you can use the pre-built ones. This will let you run Motion or any other software on Ubuntu ARM. I'm working on the RK3188 quad core kernels now, but in essence you be able to use this to run hand rolled Ubuntu on any ARM based platform.
