Traditionally, these products have been based on proprietory OSs such as Nucleus and VxWorks. Now we are redesigning a few of our products and I am trying to convince my company to go down the Linux route. Understandably, our management is quite sceptical about that and so I was asked by our CTO to recommend a few RTOSs which have mature Networking stacks and which work well on ARM platform. I know that there are many embedded linux based distributions out there. There are commerical ones such as Montavista, LynuxWorks, free ones such as uclinux, muLinux and some Linux like distros such as Ecos, but which is the most stable and best community supported embedded Linux distribution out there?
