Taking the next steps

Phew! We got it done! Now you should know the Yocto Project build system basics and be capable of extending your other areas of knowledge. We tried covering the most common daily tasks using the Yocto Project. There are a few things you might want to practice:

  • Creating bbappend files to apply patches or make other changes to a recipe
  • Making your custom images
  • Changing the Linux kernel configuration file (defconfig)
  • Changing the BusyBox configuration and including the configuration fragments to add or remove a feature in a layer
  • Adding a new recipe for a package
  • Making a product layer with your product-specific machines, recipes, and images

Remember, the source code is the ultimate knowledge source, so use it.

When looking for how to do something, finding a similar recipe saves you time testing different approaches to solve the problem.

Eventually, you’ll likely see yourself in a position to fix or enhance something...
