Thx for your reply .

So which chain supports Nommu ?

Br no mmu support
Crosstool no mmu support. 
Ct-ng no mmu 
Uclinux support but requires a no mmu tool chain. 

Building a toolchain by hand.

The reason why we dont want to use an mmu is complex , there is a thread on
it in ucLinux but basically building a type safe , memory safe micro kernel
OS since we run a single address space with compiler based checks an MMU
just becomes an overhead. Rather than the green field code we have been
working on for 2 years we can start with uClinux which will help things
along .
