This topic explains how to build a Legato update for a Target Device.

Make an Update for a Target

All supported builds use the make tool and have pre-configured makefiles included in the Framework.

Note: Make sure you have the appropriate toolchain installed before you run make.

Run make to build the framework for the target from your Legato Root Directory:

$ make wp85  \\makes an update file for a WP85 series device

$ make raspi \\makes an update file for a Raspberry Pi device

This will build a system update pack for the target, located under the build directory for your target (e.g., build/wp85/system.wp85.update).

Note

If you are having problems successfully running make you may need to remove ccache from your host.

$ sudo apt-get remove ccache

See basicTargetSW for details on how to install your system update pack onto your target device.

Update a Target

To update the app and framework binaries on your target use the update tool to pass the system update pack to the target device for installation.

$ update build/wp85/system.wp85.update 192.168.2.2
