Bitbake cheat sheet

Intention

This page is intended to make the live of new developers easier. Feel free to add all your usual bitbake commands to this page

Start a build

To get a package build just type

 bitbake foo

where foo is the name of the package without any extension or version number.

Clean up

 bitbake -c clean foo

This command will clean up your tmp dir for the given package. It is very useful if you work on a new .bb recipe. Without it your changes to the recipe may not work.

Working with tmp/work

A thing you usually do not want to miss is to be able to recompile your source code if you change a line in it.

 bitbake -f -c compile foo

will only recompile your source nothing else after that do a

 bitbake foo

to get a new package
