RE: [avr-gcc-list] ATmega32/ATmega323

[Ron Kreymborg]

I see what you mean David. However, as the linker fails (using atmega32)
with the message:

Unrecognised emulation mode: avr5
Supported emulations: avr85xx avr1200 avr23xx avr44x4 avr4433 avrmega603
avrmega103 avrmega161

and there is an avr5 linker script, I would have thought this would be the
one it used.

Your idea of patching the avrmega161 script files for the bigger memory
works for me also. But there is obviously a bug here somewhere. Can anybody
suggest where to look?

In passing, I upgraded to the version from avrfreaks about a month ago. It
seems you no longer get the library source code! Is this available from
somewhere else on avrfreaks? Or from some other site?
