There have been a few over the years, but generally if you can run Linux with the MMU enabled most everybody chooses to do that. I had uClinux running on the Freescale ColdFire M5475 dev board a few year back. And Freescale also have full MMU linux running on it. I am pretty sure Hyok S. Choi had a couple of different ARM based boards that he ran both with MMU enabled (full Linux) and MMU disabled (uClinux) when he wrote his paper comparing performance of the two. I don't recall which boards he used right now though. > I checked about uClinux homepage (http://www.uclinux.org/ports/), the list > of "Ported Microcontrollers and Microprocessors" are all without mmu, so I > think these target on the uClinux homepage can not run full linux. > Could you tell me some other url address with more information about "the > supported list"? Theres no single definitive list... But the code you get from uclinux.org is full Linux plus extra non-MMU bits. It still runs on the same targets it runs as the original linux versions that it is based on.
