Hi NerdKites,

what other bootloaders for ATmega168 are worth a mention, apart from foodloader? Foodloader is simple but lacks fuse programming, and I'd like to use the two XTAL pins for I/O. I promise not to complain here if I shoot myself in the foot. :)

I tried googling around for AVR109 and AVR910 bootloaders but to little avail. What am I missing?

Hi wayward,

If you skim through chapters 25 and 26 of the ATmega168 datasheet, you'll see that Atmel actually made it impossible for any bootloader to program the fuses except for the "lock" fuses. Therefore, no amount of googling will find you such a bootloader. So you'll actually have to find an ISP-type programmer, such as an ATAVRISP2, or a DAPA or DASA type programmer, if you want to change the fuses and free up your XTAL pins.
