Appendix D: Updating Firmware
METHOD 1: Updating Firmware Using PC App
This method can be used when updating newer control boards
with bootloader version 2.0. This method will not work for older
control boards with bootloader version 1.0 (approx. unit serial
numbers -17 and lower); for those, see METHOD 2. Note that
METHOD 2 will work for all control boards.
The firmware comes as a .ZIP file named:
MGL GEN2 Bootload Firmware Vxxx.zip
where xxx is the version reference, e.g. 366 (version 3.66).
This file can be downloaded from www.nordicghp.com, menu
For Dealers --> Download Software.
1. Download the file to your PC. When prompted, "Open" the
zip file. If the zip file is Saved instead of Opened, find it in
the web browser's Downloads list or at the bottom of brows-
er window and click on it to open. In the window that comes
up, drag the folder containing the required files onto your
desktop so that it can be found easily, e.g.:
\Desktop\MGL GEN2 Bootload Firmware V366
Also be sure the latest PC App version (e.g. v2.00) is in-
stalled, which is listed alongside the firmware on the web
page. If needed, install a new version as per those instruc-
tions, and uninstall older PC App versions to avoid their acci-
dental use (which can corrupt control board parameters).
2. In that folder on the Desktop, there will be three files:
MGL_GEN2_V366.production.hex
PIC32UBL.exe
USB Bootloader Instructions.pdf
Note that on most computers, the file extensions (.exe, .pdf)
will be hidden.
3. Connect a USB (printer) cable between computer and control
board.
4. Launch the PC App version that matches the firmware (e.g.
PC App 2.00 for firmware V3.66). After it is installed, the PC
App can be started using the entry found under the "M" sec-
tion in the Windows START menu, which is accessed using
the 4-rectangles icon normally found at the bottom left corner
of the computer screen.
5. In the PC App, click on the Connect button to connect to the
control board.
6. Go to menu Tools --> Update Firmware. The following
message box will appear:

7. Click on YES. The following message box will appear:

In the window that opens, click on the USB Enable check
box.
If device fails to connect and an error message is
displayed, the board's bootloader may be older than
v2.0. It will be necessary to instead update the firm-
ware via jumper pins (METHOD 2), as per the next
section.
