I appreciate the answer, I think this topic has been discussed several times, so thanks for spending time re-visiting it once again. I have looked at both the examples/standalone code and the README.standalone. I have also seen 1) http://old.nabble.com/-U-Boot--How-to-get-GPL-free-standalone-programs-with-u-boot-td27182861.html [1] 2) http://lists.denx.de/pipermail/u-boot/2009-August/058650.html [2] 3) http://osdir.com/ml/boot-loaders.u-boot/2003-11/msg00072.html [3] 4) http://osdir.com/ml/freebsd.embedded/2008-01/msg00019.html [4] 5) http://old.nabble.com/Re%3A--U-Boot--How-to-get-GPL-free-standalone-programs-with-u-boot-p27338654.html [5] Some of these are forums, rather that mailing lists, I apologize for not being specific in my previous message. The part that is not clear to me is if a conclusion has ever been reached as to the availability of a set of GPL-free headers that can be included in a stand-alone application. I think the GPL is quite valuable, but there are situations involving closed-source software where GPL licensed source files must be avoided (I'm sure this is news to nobody). Has such a set of GPL-free headers been developed, or must I develop them myself if I want to use them?

Eventually this needs fixing. >Patches are welcome. In the latest U-Boot sources, this issue seems to still exist; headers available for inclusion in stand-alone application seem to include the GPL license language. I can't find equivalent headers that are "GPL-free", but maybe I am looking in the wrong place. This last comment includes mention of the "allowed" file list; I can't locate anything of this nature either. Again, thank you for your time and best regards, Jim Original message: ------------ Subject: Re: [U-Boot] U-Boot "public API" example desired Date: Thu, 06 May 2010 19:42:50 +0200 From: Wolfgang Denk To: j...@sdateam.com [7] CC: u-boot@lists.denx.de [8] References: Dear j...@sdateam.com [10], In message you wrote: Is there an example available of the use of the U-Boot "public API" or of a "stand-alone application", that can be, or is, sanctioned by someone who would definitely know (for example, Wolfgang Denk) as being not a derived work?
