  • Author: Sierra Wireless
  • Version: 1

This page describes the procedure to update WP76xx with Firmware Release 17.1

WP76xx Release 17.1 is a maintenance release that delivers critical security patches, bug fixes, and stability improvements to enhance system reliability.

 

WP76xx firmware is available:

  • As pre-built images ready for installation on Windows or Linux hosts. See Installing Firmware Release 17.1 Updates, below.
  • As separate components for developers that wish to build custom Linux Distribution or Base Legato System images.
    See WP76xx Firmware Release 17.1 Components to create custom firmware packages.

Important note for the 2-stage AV FOTA firmware upgrade:

  • All legacy firmware releases can only be upgraded by AV FOTA to the latest version via Firmware 16.3. The AV FOTA process to intermediate Firmware Release 16.3 must firstly be completed before proceeding to the AV FOTA process of upgrading to Firmware Release 17 and later versions such as Firmware Release 17.1.
  • No firmware downgrade back to prior firmware releases is allowed once the firmware is upgraded to Release 17.1.
 

Installing Firmware Release 17.1 Updates

The following methods can be used to install pre-built images on WP76xx modules:
(Windows)
'One-click' tool

 1. If not already done, download the latest USB driver and launch the executable.
 2. Download the Firmware 'one-click' (.exe) file for your carrier (Note: If your carrier is not listed and you are unsure which Generic to use, check with your carrier.):

 3. Connect the target's (e.g mangOH) USB cable to your host
 4. Launch the firmware executable (.exe file) and follow the instructions.
MBPL (Linux)

 2. Follow instructions from the Software Integration and Development Guide for Linux USB Platforms included in the MBPL (Mobile Broadband Package for Linux).
Legato Plugin for Visual Studio Code (Linux)
 The Legato Plugin for Visual Studio Code connects the Legato tools into an IDE to ease the learning curve of Legato, and provides a map of the definition system for you to easily build systems for your smart module.

  1. Download and install Visual Studio Code for Linux.
  2. In the Visual Studio Marketplace, search for "Legato" and install the plugin.
  3. Install Leaf on your dev machine if not already installed.
  4. Install the SDK for the latest stable WP76xx package:
    1. Use the Leaf menu to add filters (@wp76xx and @stable) to find all stable WP76xx packages.
    2. Select the latest package (the first one in the Available list).
    3. Install the SDK to a profile — click Add to profile..., name your profile and then follow any prompts in the terminal window.

Note: All images are contained within the SDK and can be updated from the Target menu using the Flash .cwe/.spk to a target(via swflash) option.
Leaf Workspace Manager
 On the Legato Application Development Kit page, follow the Leaf Workspace Manager instructions to download and install Leaf and set up your CLI development environment. 

Important: In the 'Search for a package' step, use the following to search for the latest WP76 packages: leaf search -t wp76xx -t stable -t latest
