Consumer Device With Open CPU Out of Beta Soon

Posted by timothy on from the for-finger-painting-in-public dept.

lekernel writes "After years of passionate and engaging development, the video synthesizer from the Milkymist project is expected to go out of beta in August. Dubbed 'Milkymist One,' it features as central component a system-on-chip made exclusively of IP cores licensed under the open source principles, and is aimed at use by a general audience of video performance artists, clubs and musicians. It is one of the first consumer electronics products putting forward open source semiconductor IP, open PCB design and open source software at the same time. The full source code is available for download from Github, and a few hardware kits are available from specialized electronics distributors."

    I'm not particularly happy about my chances of legally
    reusing code that starts like this:

      BTW, that license was from the tarball at http://www.milkymist.org/socdist/milkymist-1.0RC3.tar.bz2

      Before bothering with that, I actually tried figuring out the license by looking at Lattice, but other than reassuring verbiage about free, I came up blank when looking for an actual license:

      http://www.latticesemi.com/products/intellectualproperty/ipcores/mico32/mico32opensourcelicensing.cfm?source=sidebar

      And, of course, most of the Lattice junk in the source tarball, and the documentation at the milkymist site, can't even be retrieved from Lattice itself without registering and executing some sort of license agreement:

      http://www.latticesemi.com/dynamic/index.cfm?fuseaction=view_documents&sloc=01-01-08-11-48&source=sidebar

      Lame. BTW, the main article links to http://www.milkymist.org/.

      Which links to the SOC code page.

      Forgot to mention that I did read section 11 that you point out to. It doesn't include all the source. There are plenty of files that self-identify as being under one of the licenses referenced by section 11, but the core CPU RTL files don't seem to fall into that category.

      Color me naive/fearful/stupid/untrusting/whatever, but when I see a license that covers both open source components and non-open source components, and a source file with a copyright notice that doesn't say anything about the code inside being under any kind of open source license, and in fact starts off by saying "This confidential and proprietary software ...", why the hell would I assume that the "open-source" parts of the license apply to that particular source file?
