But I am truely a novice when it comes to CPU/board bringup.. (I've assisted in it, but my expertise and history is in userspace development.) The things that can take massive amounts of time on these new processors/boards are hardware bugs (cpu and board) as well as device drivers for new on chip devices. I have seen more then one engineer going bald due to hardware bugs, especially a board that the customer said "But it runs VxWorks, why doesn't it run Linux?"... --Mark Dmytro Bablinyuk wrote: > Not a lot of our people experienced in PPC assembler (including myself). > Actually not a lot experienced with PPC at all. > Roughly, from your point of you, how major changes in the kernel could > be?
