Linux is being used more and more in high volume embedded products mainly because it is royalty free, but also because there is a plethora of libraries available for doing almost anything. However Linux development can be a minefield for many reasons. Micro Passion can be a trusted partner for developing you Linux solution.
Licensing advice - Many Linux libraries are provided under a general public license (GPL). While it is possible to sell commercial products utilising GPL libraries, the licence requires that source code for the applications created be made available. By choosing the libraries used carefully it is possible to write commercial applications, without the requirement of making source code available.
