@Neil Cherry right on the main page there is a link to the dropbox on the left hand side.  Here is the link:

Sent you a PM to get your email to add you to it to have write privs.

I also got the SDK toolchain building.. I can actually build a kernel with it!  Not that I have tried yet. But its an interesting thought.  It looks like the sample code (posted in the dropbox) also has code for image detection and using the camera?  I have not fully wrapped my head around the video kernel modules yet nor the code.  I am not sure I understand how the SDK came with the camera code / support?  Unless the Hi3518 is specifically developed for a video camera application.   Kind of like how the RPi has the display port built in... Not a great analogy but you might get what I am saying :)

I haven't gotten as far as building the tool chain. I did try to connect to nfs but that failed (missing kernel module on the camera?). I wouldn't start with the kernel, but I would start with a simple hello world. Then you'll know if you have something that works with the camera. from there w can kill App8518and message and run the sample application to learn what it can do. The App8518 seems to do an awful lot.

In the drop box? I only have the link for the mtd file.

@Neil Cherry roger that "hello world" its my plan too.  Just get a binary compiling and then xfer it over and make sure it works.  I have been using ftp to do all file sharing.  So as far as I can tell it looks like the Hi3518 is a SoC with a camera on it (or interface for a camera).  Very interesting.  I am not exactly sure why they did kernel modules for a static device but whatever.   I will keep you updated on my progress.  I am about to get smashed with 30" of snow tomorrow (I am in the DC metro area) so I may be online or not :)  I might have some time to play however!

Very cool! My funlux-cap.exp script pulled the img from my camera. The mtd1 & mtd3 are different between your's and mine. The config could be because we have different setups.
