MReX Firmware Upgrade
In order to update the MReX firmware you will need:
1. The WTE Bootloader Tool (available from http://www.wte.co.nz or provided if required
from info@wte.co.nz).
2. Serial TTL cable.
3. An appropriate encrypted hex file supplied by WTE Limited.
Note: Attempting to load a hex file not intended for use with the MReX will render the MReX inop-
erable. Uploading firmware should only be performed if instructed to do so by WTE Limited or an
authorised agent.
Firmware Upgrade Utility
This bootloader software has been customised by WTE to simplify the firmware replacement pro-
cess for the MReX, This application automatically handles erasing and verifying of uploaded firm-
ware. This utility does not perform any decryption function (decryption is carried out by the
MReX itself).
