Getting the Status of the Recipes in Your Workspace

Use the petalinux-devtool status command to list the recipes currently in your workspace. Information includes the paths to their respective external source trees.

Modifying an Existing Recipe

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

Figure 1. petalinux-devtool modify

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

Figure 2. petalinux-devtool build

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

Figure 3. petalinux-devtool build-image

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 any layers, you need to update the recipe append file before running the reset command.

$ petalinux-devtool reset linux-xlnx

Figure 4. petalinux-devtool reset

Note: You can find a list of examples at https://www.yoctoproject.org/docs/latest/ref-manual/ref-manual.html#ref-devtool-reference. Make sure to use petalinux-devtool in place of devtool in the examples.
