Prerequisites
sudo apt install gcc g++ \ python3-distutils python-is-python3
Images
Images are defined in recipe files. In order to separate them from package recipes, there is a convention to put image recipes into a folder named images. Making use of this, we can list all images defined by all layers via
ls meta*/recipes*/images/*.bb
Using devtool
Use devtool to make changes to an existing recipe and automatically generate an append recipe from those changes.
