I am considering Freescale i.MX processor for my project, and I
happenily know the Freescale also supports Linux.
I would like to know what kind of IDE is typically used by developers
of Freescale Linux, CodeWarrior or Eclipse? Does Freescale provide
something similar to WindRiver Workbench?
I was wondering why there are so few
threads about the Freescale MCUs.
They don't seem to be very popular,
or am I wrong? I'm about to embark
on a small embedded project, based
on a Freescale HC08GB60 (a timer
with a couple of bells and whistles)
and because threads quite often deal

Could you please let me know of Freescale (Motorola) microcontrollers
that have three UARTs?
(The parametric search on the Freescale website is really difficult for
this kind of a search.)
Thanks a lot for your help.
