Boot loader

The MD04 has a built in boot loader meaning the firmware may be updated by the user when a new

version becomes available. The boot-loader is based on the USB boot-loader provided by Microchip as

part of their "Microchip Application Libraries" and can be downloaded from here.

To put the MD04 into boot loader mode you should now turn any power supply to the MD04 off and

place a link across the two pin header. Now run the boot loader you have downloaded and insert the

USB cable, you should now have a screen similar to that below allowing the software hex to be re-

flashed in the event of a future update.
