OK.  So I'm sure someone has already brought this up
but I'm new to the list so I have to ask.

Is anyone working on adding support for the AT90CANxxx
chips to avr-gcc, specifically under the UNIX/Linux
platform?  I guess support has been added in the
opensource winavr project but I hate using windoze and
would prefer to do all my development under linux.  Is
this being addresses?  Has it been addressed?  Do any
of the core programmers intend to address it?

What is needed for AVR-GCC to support the AT90CAN128 () that isn't already provided by the Atmega128 support?

That is, why not just use


for the AT90CAN128?

That's what I was planning on doing; is there some reason why that wouldn't work? Did I miss an important detail somewhere (uh oh... gotta read the datasheet)?

You might need to supplement avr-libc by adding some register/bit definitions for added CAN hardware or maybe slightly different linker scripts, but this can be done by the user and has no impact on AVR-GCC.
