      If you're willing to go under the constraints of the NDA and various business practices to get access, some of the secure ICs are quite well documented and even have decent tooling. But outside NDAs and approved paths for access, info is limited.

      That was my point. I can buy some of these chips in qty 1 on digikey, but without any documentation for the host interface I can't use them. And I don't want to sign an NDA for an open-source project.

      It's not clear that signing the NDA and utilizing the chip in a real design would prevent you from producing open source software which utilizes the chip in your design. You just have to ensure every bit of what you code is strictly necessary to the design and don't explain.

      Yes, but being under NDA would force you to not comment register writes, etc and generally produce poorly maintainable code. Unless you had a "secret" version of the code and then deleted the comments for the public copy.

      If you have a "secret" version and only publish something with the comments removed then you are in violation of clause 2 of the open source definition, i.e. it is not open source anymore.

      Interesting perspective. Are missing comments considered missing code in the spirit of "fully" open source? I wonder what @MicrochipTech has to say, given this conversation mentions their ECC608 crypto chip.

      For example: clearly naming a register but simply not commenting what bit patterns are being stuffed or why... Is an open source violation? It's not obfuscated. It is the original, full source.

      What? No! Please just *read* the text I quoted. If you have two versions of the code, one that you edit, and one that's generated from the first, then releasing just this generated code, not the one you'd edit, is not releasing the "source code" wrt OSD.

      Yes, I did read it. Source code with or without comments should compile exactly the same. So you are saying that comments are source code? My only point is that it is an interesting question. 🙂

      It is not an interesting question. It is a trivial question wrt OSD. And I only made a statement about OSD semantics. The file the person writing is edition = source code. A different file generated from that source file = not source code. Doesn't matter what the diffs are.

          Ok, good point. So you are saying if the source code used to compile has key comments, then those comments are part of the "open source" in entirety. I had just not considered comments quite that way. TIL something new (clearly I am not fully versed on OSD, thanks for clarifying)

          It doesn't matter what kind of modifications are done. Removing or changing any comment, renaming variables, changing indentation, whatever. You have to release the files you are editing, not some derivative of them.
