Hi James
I have begun to design a system based on the ARM7DI core without MMU and
was going to use Linux but the port I chose is uCLinux.
see:- http://ryeham.ee.ryerson.ca/uClinux
They already have a stable kernel running on some 68k chips (Dragonball,
ColdFire etc.). These microcontrollers have no MMU.
I haven't heard of anyone else trying to port uCLinux to ARM yet, so I
welcome your company. I should have my hardware ready by the start of
June, currently I am learning to build cross compilers and develop a
working knowledge of the Linux kernel. I recommend joining the uCLinux
mailing list.
