A week or so ago someone suggested changing the fuse on the Atmega2560 to be different from the default because that caused problems with serial communications.
I am having that exact issue with a stand-alone processor, but can't find that post for the life of me.
I'm currently using:
LFuse = 0xF7
HFuse = 0xD8
EFuse = 0xFF
Does someone remember what the recommended setting was (particularly the low fuse: the clock selection)?
I manually changed the fuse in this case to what sounded, from memory, like what someone had said. Looks like I got it right. Hmm. Still not working though. Oh well, thanks for the confirmation.
Is that only for the 1284 ?
The 2560 is not the full swing in boards.txt:
mega2560.bootloader.low_fuses=0xFF
mega2560.bootloader.high_fuses=0xD8
mega2560.bootloader.extended_fuses=0xFD
