Hello,
I have a question regarding GPL and NDA issue.
I have documents for a specific chipset which I get with NDA. And I'm trying to port Linuxbios on that chipset. As LinuxBIOS is GPL, I know I must make my port publicly available. In this case, Is it a violation of NDA or not? Does it depend on NDA?
Violating the spirit of an NDA has business consequences, regardless of the legal ones so keeping good faith is necessary.
But that runs two ways. If you a customer cannot use their product because of NDA issues you have leverage to work out the issue with manufacturer of the hardware.
In general a NDA does not preclude you from working on a chipset.
In many cases there are extra constrains to releasing code before the hardware is publicly available. So a source/binary release may need to wait until the official launch of a product.
In all cases you can develop code and not release either the source or the binary while you have an NDA. And that meets the terms of the GPL.
For source code release the stipulation is that anyone who can get the binary needs a means to get the source.
In a practical sense I have not yet seen hardware where knowing how to program it appears to reveal how to build it. Which is what I would suspect manufacturers would be worried about.
Most NDA issues I have seen have come out of business NDA reflex and can usually be resolved. It also helps in the business arguments that alternative suppliers of competing hardware have been successfully worked with so you can threaten to switch hardware or even switch hardware if you cannot use a piece of hardware because of NDA issues.
Also people tend to be particularly prickly NDA wise on the top of the line hardware. In most cases embedded products are a commodity and volume market, with more custom systems being built. So on the embedded side I would expect the NDA issues to be easier to overcome.
