7.0 Device Maintenance
7.1 Introduction
This section is not part of the default usage of the evaluation board. It is to be used as a reference in case you have been in contact with the
support team, and they invited you to run some of the following actions.
7.2 Firmware Upgrade
7.2.1 Firmware Upgrade Introduction
This section is only informative in case you are invited to upgrade the SW of the evaluation board.
The evaluation board you received is normally loaded with up-to-date software and it is ready to work. However, your support at Sequans
may ask you to upgrade the default software for some reasons at any time.
To upgrade your board you need to obtain the following from Sequans:
 The Sequans Firmware Upgrade (SFU) Tool
- sfu_1.1-xxx
 The SFU User Manual
- Monarch_SFU_UserGuide-RevX.pdf
- The new firmware to upload on the evaluation board: it is a file with the .dup extension (e.g., GM01M-REV3_B2B3B4B8B12B20_B-
BA1-RFA3-SKY6800131_LR5.1.1.0-34234.dup)
The first time you use SFU, you need to install it on your PC.
Figure 10. Sequans Firmware Upgrade (SFU) Program
Note: The SFU program program operates on "UART 1". Refer to COM Ports Overview Tables on page 5 to map it for your setup.
7.2.2 Upgrading the Evaluation Board
For detailed SFU usage, please refer to the SFU User Manual document.
Typical upgrade operation:
 SFU works UART 0, thus plug the mini-USB cable from your PC to the USB Port X of the board.
 You also need to open a console to monitor the upgrade activity. The console is accessible through UART 2 (also plug the mini-USB cable
from your PC to the USB Port Y of the board).
 Open a CMD in Administrator mode
 Change the working directory to SFU installation directory
 Run the following command:
sfu upgrade -b 921600 -z 2 COM## <xxxxxxxxxxxxxxx.dup>
COM## is your COM port associated to UART 1; xxxxxxxxxxxxxxx.dup file is the new Firmware to upgrade
