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, http://www.atmel.com/tools/atmelavrtoolchainforlinux.aspx Other may be built using Bingo's scripts, see http://www.avrfreaks.net/forum/script-building-avr-gcc-451-linux JW _______________________________________________ AVR-GCC-list mailing list AVR-GCC-list@nongnu.org https://lists.nongnu.org/mailman/listinfo/avr-gcc-list
