Kyocera KR1, GNU Public License - GPL

Michael

Since, the KR1 is Linux based, and Linux code falls under the GNU public license (GPL). This requires that the source code be publicly available. Once this is available, it will allow many new features to be added directly to the KR1 via customer Firmware (new cards, new phones, many new features, etc.)

So, Kyocera, when will this happen?

All the stuff is being put together right now. Should be available, "soon." Mr. Green

A good portion of the code is already available in various other archives from D-Link in their GPL dump section and other places. However the "current version build tree" including the .config file from the linux kernel build directory would be most helpful.

Hopefully DLink will release an image of the 624S so I can merge in USB Storage support...

Has Dlink/Kyrocera released the GPL yet? I looked on Dlink's GPL site and saw no sign of it.

Oh yeah...I forgot about this. There's a tarball hanging around somewhere, I'll find it.

The GPL license and link to download the files are in progress. They should be available on the Kyocera Wireless website in the next couple of days.

Mackieman,

This is great news, thanks for the update.

Malicioius compliance with the GPL?

Where is the .config (yes, dot-config) from the linux-2.4.x directory or instructions on how to build it from the tree? I can build kernel modules (that actually load), but unless I can fix the USB so it doesn't think everything is a serial port, but I need to recreate the kernel image, and ultimately the BIX files, but I think I can figure out the latter.

There is one for the 624s GPL dump, but it has USB storage, and not USB serial.

(If you are wondering why I've not done more with the GPS end, it is because I'm having fun trying to do far, far more).

I noticed the lack of a .config file. It was sent back to D-Link to repair. The fixed version should be on the Kyocera website on Monday. I have no idea why it takes so long to make an update but I'm sure they have a reason. So there ya go.

Thank you. I also noticed with the 624s at least some missing directories, i.e. their own config could not reproduce the kernel image. Having hacked the kernel, I can get around them, but if they are vital for the proper functioning, I would like to know.

Basically I'd be satisfied if I could go into the linux directory and type "make" and get basically what is running the KR1 (I already the toolchain properly located in /opt, where I already have them so the kernel can make to some extent).

I'm certainly not a linux architecture expert but I would be willing to bet that you will not be able to completely compile from the available GPL code even with the .config file. They only released the stuff they used that was already GPL licensed. I'm sure there are many things they developed themselves that will not be in a GPL release package. I don't know of anything that could be done to remedy that.

There would be some non-gpl code, but any derivative work of a GPL program is covered under the GPL (unless you happen to be the copyright holder). Excerpting something from one GPL file into a second is considered a derivative work.

It is exceedingly difficult to build something within the kernel source tree without causing a GPL violation. The code in the subdirectory must be 100% original to be excluded. Even Sharp (and some others) who include SD device do so as modules to avoid the problem. Tivo ended up digitally signing the kernel.

I don't think I could recreate the entire router, but I should be able to rebuild a kernel image. Unless DLink is far better at managing IP than most.

A day late and a dollar short, it's finally out there.
