hi sir,i tried to check second method of this link...
In the above link,
they mentioned like below "After recompiling the bootloader’s source files, I flashed the new bootloader using AVR ISP MK II. I also had to make sure that the BOOTRST fuse was set in the ATmega2560’s fuse settings."....here new bootloader means exactly,which file i need to flash....
can u please suggest linux commands to flash bootloader using arduino uno as isp programmer to arduino mega 2560?
Thank you in advance
