Introduction[edit | edit source]
Deployment of Embedded Linux systems is the typical operation which follows the development phase. When the application is ready and fully tested in the develoment environment, it's time to take the system to the field for the “real work”. This phase brings a lot of concerns to cope with, for example creating a suitable root filesystem, saving the data properly, implement successful on-the-field update strategies. This how-to guide explains how to solve the problems connected to the deployment of an embedded linux system.
The development environment[edit | edit source]
The following figure illustrates the typical developing environment for an Embedded Linux system: it is composed by a host machine and a target machine.
The host (usually a PC or a virtual machine running the Linux operating system) is used by the developer to (cross-)compile the code that will run on the target, for example a Dave ARM CPU module such as Lizard or Naon. The Linux kernel running on the target is able to mount the root file system from different physical media. During the software development, it is very common to use a directory exported via NFS by the host for this purpose. Moreover, the linux kernel is usually retrieved by a simple network transfer protocol like tftp.
