Hi bbilen or however your name is... > I'd like to run RT Linux on a Viper Development board (PXA255 , > http://www.eurotech-inc.com/single-board-computer-pxa255-pc104-viper-lite.a > sp) . Kit came with a custom Linux (2.6.16.28). I checked RT patches here: > http://www.kernel.org/pub/linux/kernel/projects/rt/ but there are not any a > 2.6.16.* versions.

In pages like this: > http://lkml.indiana.edu/hypermail/linux/kernel/0606.1/1179.html I saw a > 2.6.16 version is mentioned. Is there a 2.6.16 rt patch somewhere? There are only preempt rt versions for selected kernel versions as porting the patches to other versions is quite some work. So you have to live with what is there. As 2.6.16 is pretty dated i would ask your vendor to give you a more recent kernel. I would recomend you to look for close mainline support for your next project...
