I don't exactly understand what do you want, but
as I know Motorola has the USB device driver for uClinux as well as for the
standalone version on their web site (www.mot.com).
I hope this helps.

Vlad.

I have an application where I am considering a ColdFire 5272 as a system
control processor.  It is going to have a big chunk of data Flash
(16-64MBytes) connected to it for FPGA loading.  We also have a USB
connection to our host CPU (dual Xeon running FreeBSD) and we would like to
be able to use a chunk of the Flash for a boot loader.

The questions I have are:
1. How hard is it going to be to implement a Bootable USB Device with a
5272?  Has anyone done it?
2. How much external RAM and Program Flash do I need?
3. Is there a better processor for the job?

Thanks!
