Hi Ulisses,
many thanks,
i am wandering why they use a PPC (MMU) to run at 50 Mhz, just with a
flash and an sdram ...
Anyway, thanks for the info.
regards,
Angelo

Hi Ulisses,
thanks for the reply,
i can use main line linux of course, but i have now some pratice with
uClinux, and also, probably i can work easily with uclinux, also the
final kernel image should be smaller. Daos it have a sense ?
Well, AFAIK uClinux is mostly useful for those on non-MMU platforms,
because it provides not only a fine tuned kernel, but also patched versions
of many userland utilities which would normally only run on MMU-enabled
hardware. For a MMU system, using a cross compiler for the kernel and
something like buildroot (http://buildroot.uclibc.org/) for the userland
would probably be just as effective, while keeping you closer to the
current mainline bleeding edge.
Is uClinux only for development / open boards ?
Not at all, but see comments above -- it's really more interesting to those
working with non-MMU. Also, development boards which officially support
Linux/uClinux usually provide drivers for all hardware included, some of
which might not be on mainline. On a finished product, though, this usually
involves getting your hands on the source code for the image on the system,
which might not be uClinux at all (and then you'd be left with the job
trying to port all drivers from whatever kernel they use to uClinux).
Could it work selecting PPC ?
Don't know the answer for this one. Anyone?
Regards,
Angelo
