is anybody using an atmega128l with gcc successfully yet? we would
really like to benefit from the second uart, but are unsure if we can
port our code from 103 to 128....
Yes I have gcc and binutils working for the mega128, attached are some
patches for the compiler and binutils that you need to rebuild.
You also need a new library for the defines for the mega128, I'm still
working out the best library for that newlib or avr-lib, avr-lib has its
problems, new-lib makes larger code.
Have a look at this message about building gcc etc,
http://avr.jpk.co.nz/pipermail/avr-gcc-list/2001-November/001020.html
and
http://avr.jpk.co.nz/pipermail/avr-gcc-list/2001-October/001000.html
