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,
