Important: Upgrade the firmware before upgrading the Legato application framework.
Contact your Field Application Engineer (FAE) to upgrade AR series targets.
You must upgrade your firmware before upgrading Legato. See WP Firmware Download and Instructions for details.
This procedure is for those running Legato from the source packages.
Ensure you've upgraded firmware and you have the latest source code from GitHub before starting to upgrade Legato AF.
On your development host, go to the Legato build toolchain installation directory (/opt/swi) and remove all files:
$ cd /opt/swi
$ sudo rm -rf *
Installation packages (including toolchain downloads) are available at the Sierra Wireless Source Legato Downloads page.
Select toolchain for either 32 or 64 bits and copy it to /opt/swi
$ mkdir -p /opt/swi
$ chmod u+x [toolchain.sh file]
$ [toolchain.sh file]
You may need to use sudo to run mkdir.
Then, follow install and build info in the Build Platform docs
See Legato documentation for full information.
