WebHow the New Bootloader Works. The updated bootloader will first look for a valid sketch at the memory address 0x10000. This ensures backwards compatibility with the standard sketches uploaded from the Arduino IDE. If no valid sketch is found, because maybe a softdevice has been placed in that portion of the flash, the bootloader looks for a ... WebIn theory a boot loader could do its job by directly accessing the bare metal, but 512 bytes would be a very small space for that.
