I have an Atmega2560 on a protoboard and i'm looking for the correct bootloader. The bootloader folder in my arduino directory only has the stk500boot_v2_mega2560.hex file located in the stk500v2 folder. Is this the correct one? Do the fuse bits below look correct?

I'd like to add a question regarding atmega 2560 chip. Has anyone tryed to use 2560V version? Should it work with the same bootloader and diferent fuse settings (8MHz) or...?

Regards,

Peter

Yes that is the right bootloader, but dont use that one. It has a bug in (I wrote it).

The bug is any sketch with "!!!" will hang the bootloader

I have tried to attach the new bootloader hex file but it gives me a "Folder full" error

send me a pm with your email address and I will send you the updated file
