Adding a New Recipe to the Workspace Layer
To add a new recipe to the workspace layer, use the petalinux-devtool add command. For $
petalinux-devtool add bbexample
https:://github.com/whbruce/bbexample.git This command fetches the
source from the specified URL and creates the recipe bbexample in the Devtool
Workspace directory.

Use the petalinux-devtool modify command to begin modifying the
source of an existing recipe. This command extracts the source for a recipe to the
Devtool Workspace directory, checks out a branch for development, and applies the
patches, if any, from the recipe as commits on top.
Use the following command to modify the linux-xlnx recipe:
$ petalinux-devtool modify linux-xlnx
Building the Recipe
Use the petalinux-devtool build command to build your recipe. This
command is equivalent to the bitbake -c populate_sysroot command.
You must supply the root name of the recipe (i.e., do not provide versions, paths,
or extensions), as shown:
$ petalinux-devtool build linux-xlnx
Building Your Image
Use the petalinux-devtool build-image command to build an image
using the devtool flow. This will include the recipes which are the workspace
directory. When running this command you must specify the image name to be
built.
$ petalinux-devtool build-image petalinux-image-minimal
Resetting the Recipe
Use the petalinux-devtool reset command to remove the recipe and its
configurations from Devtool Workspace directory. This command does not add/append
changes in the Devtool Workspace to the any layers, you must need to update the
recipe append file before running the reset command.
$ petalinux-devtool reset linux-xlnx
petalinux-devtool in place of devtool in the
examples.
