Hi,
Can I run uClinux on platforms that has MMU
You could, but why would you want to?
If your processor has VM then wou will be better of using it. Without VM you suffer more problems from free memory fragmentation, no dynamically growing stacks, ne memory protection between kernel and processes, etc.
There are currently no patches for processors with VM to run with the CONFIG_NO_MMU support of uClinux. (There would be a little bit of work to do if you wanted to).
Regards
Greg

Being able to run true ucLinux on i386 makes debugging and verification of software so much less painful sometimes.

For some things yes. But it is a real pain trying to track down memory corruption and stack overflow problems in applications. They have a tendency to take your the whole system...

Wouldn't an ucLinux-version of uml be a good idea? :-)

Yeah :-)
We sort of have better than that now. There are quite a few emulators that run under standard Linux that will quite happliy run uClinux. There is xcopilot (m68328), coldfire (5206), ARMulator (ARM), tsim (SPARC leon) and or1ksim (OPENcores OR1000). I am sure there is more!
