How much of POSIX do you need? eCos does not implement everything. uCLinux will have more of it. > 2. Does eCOS supports mmu less processors? Yes. It does not use the MMU, so it makes no difference if there is one or not. > 3. Is there any port of eCOS for STR91xF ? If not is > there any ongoing project for this port?

I guess a lot of the device drivers will be re-usable on the STR91. I don't remember an OpenSource port, but it is worth googling.
