Hi Jaromil, It would be interesting to know on what basis Phillips offer the reference hardware kit. The literature refers to 'a small real time operating system' which is quite likely to be Linux kernel based, given the features of the device. MontaVista is a partner on the Nexperia, but then so is Wind River. (Wind River now do Linux as well as proprietary RTOS though). I think the latter part is the key question for libre software - 'able to exploit'. As I see it, manufacturers are increasingly concerned about hardware cloning rather than unauthorised copying of software, and this might lead to a reluctance to publish full specs. That seems to be the case with the video card market already. We need to persuade manufacturers that their products stand a better chance of success if they have a vibrant third-party development community which includes libre software developers. I'd be up for that. I presume the Xiph.org team would also be interested in seeing Vorbis libraries on the Nexperia platform. Partner programme details are at: http://www.semiconductors.philips.com/products/nexperia/home/partner/index.… While the Consumer Electronics Linux Forum already exists to do that, there's plenty of crossover between the two areas when you're talking about consumer audio devices. Cheers Daniel
