i want to flash a bootloader file for a mega2560. The .hex file only includes the bootloader code which is about 4kB, but avrdude starts programming from 0x0000 to the last address in the .hex file and not only from the bootloader start address (the part is correct programmed. Th edude seems to fill the empty code parts with 0xff). This generates very long programming times.
Does anybody know, how to solve this very long programming time problem ?
