It's hard to give a time estimate for such work because this really depends so much on the experience and calibre of the people doing the work. That said, porting eCos to a new machine architecture is non-trivial and can take someone with experience with eCos anywhere from 4-12 weeks (I've done a number of these and those are representative costs). Note: I'm not trying to make this sound like a huge task, rather that there are lots of details to consider and get correct and it simply takes time, often more than one might wish. -- ------------------------------------------------------------ Gary Thomas | Consulting for the MLB Associates | Embedded world ------------------------------------------------------------ -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
