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 in your layer.
One obvious solution is to initially extract the code into its
own layer in preparation for modification.
Another option is to use the devtool
command.
devtool
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 exist using devtool
that
enable you to use the tool to extract source code.
