The first usage is for creating a new build directory. In this case, the
|
||||
script creates the build directory <build-dir>, configures it for the
|
||||
specified <machine> and <distro>, and prepares the calling shell for running
|
||||
bitbake on the build directory.
|
||||
|
||||
The second usage is for using an existing build directory. In this case,
|
||||
the script prepares the calling shell for running bitbake on the build
|
||||
directory <build-dir>. The build directory configuration is unchanged.
