Get Started info is organized for a Quick Start and for Advanced Users.

Quick Start has two options:

bootable USB stick to get up and running fast.
dev host installation for those needing a permanent installation on a Linux host.

Advanced topics give power users info to tinker under the hood of the target device (e.g. flash or customize the Yocto image).

System Requirements

If you’re running from the bootable USB stick, a minimum of 2GB RAM is suggested.

If you’re installing the development environment and application framework on a development host, recommended system requirements for the Ubuntu desktop is at least 768 MB of RAM and 5 GB of disk space.

Ubuntu version 12.04 is officially supported, although you can try others (e.g., 14.04).

If you’re downloading Legato source and toolchain files, you’ll need a minimum Internet connection speed of 4 Mpbs.

Dev Host Requirements

Different options are available for development host PCs depending on needs. You can build, install, and work with Legato entirely from a Linux dev host, but target device recovery is only possible from Windows at this time. See Windows Dev Host.

Linux vs Windows tasks

Linux dev host is used to compile system software, flash Linux images, develop and debug applications.

Windows Host is used to flash Linux images, flash new modem firmware, recover device.

Target Requirements

Legato uses the AirPrime – AR and WP Series-Development Kit.
