So.. we can use it to reduce FW size?
yes, should be smaller. not sure how much.
i also discovered that there is a bug with arduino mega bootloader which caused the last 8KB of ROM space to be unusable.
I followed the url you provided -- it looks like it's a FUSE setting that protects the region?
yes possibly.
https://github.com/Optiboot/optiboot is an alternative bootloader with reduced size (512 bytes only), and hopefully, does not inherit the bugs from the official bootloader.
Any mods done to the bootloader will require an ISP programmer, though.
Oh wait...
This can be done with a loader program, self-programming the chip:
I think you still need to go through ISP
ow naw..
