4.3.1.2. Update Your External Source

Part of the development flow using devtool of course involves updating your source files. Several opportunities exist in the workflow to extract and work on the files. For now, just realize that you need to be able to have access to and edit files. One obvious solution is to initially extract the code into an isolated area in preparation for modification.

Another option is to use the devtool modify command. This command makes use of a "workspace" layer where much of the transitional work occurs, which is needed for setting up Metadata used by the OpenEmbedded build system that lets you build your software. Options (i.e. "-x") exist using devtool that enable you to use the tool to extract source code.
