Alternatively, the API call ''xboot_reset()'' will have the same effect. | In many cases, this allows you to use the AVRDude program command without having to manually reset the AVR.

| This will concatenate the two hex files together with the proper offsets. Please make sure to use xboot.hex and not xboot-boot.hex to ensure tha the correct offset is used (xboot.hex is relative to address 0 while xboot-boot.hex is relative to the start of the boot section). Note that the combined hex file cannot be programmed with xboot; it is intended to be written with an ISP programmer so both xboot and the application are written in one step. | This will concatenate the two hex files together with the proper offsets.
