That's strange as by 4.3.3 the avr6 (subfamily/group where both ATMega256x
belong) support was certainly already established. I use 4.2.2 for my
daily work with ATMega2560.

But it is known to be tricky to build a working package. Your "free" way is
too suspicious.

What components contains the chip infos?

All of them, in some way - that's part of why it's tricky.

You better stick to tried proven packages; and better to go for 4.8+,
benefiting from accessing FLASH through the named address space features.

One of them might be the Atmel builds,

Other may be built using Bingo's scripts, see

Hi Jan,

What is your avr-gcc version?

-bash-3.2$ avr-gcc -v

Using built-in specs.

Target: avr

Configured with: ../gcc-4.3.3/configure --target=avr --prefix=/usr/local/avr --enable-languages=c --disable-libssp --disable-shared --disable-libada --disable-libssp --disable-nls --with-dwarf2 --with-gmp=/usr/local --with-mpfr=/usr/local --prefix=/usr/local/avr : (reconfigured) ../gcc-4.3.3/configure --target=avr --prefix=/usr/local/avr --enable-languages=c --disable-libssp --disable-shared --disable-libada --disable-libssp --disable-nls --with-dwarf2 --with-gmp=/usr/local --with-mpfr=/usr/local --prefix=/usr/local/avr : (reconfigured) ../gcc-4.3.3/configure --target=avr --prefix=/usr/local/avr --enable-languages=c --disable-libssp --disable-shared --disable-libada --disable-libssp --disable-nls --with-dwarf2 --with-gmp=/usr/local --with-mpfr=/usr/local --prefix=/usr/local/avr
