Using a SOURCE_MIRROR

SOURCE_MIRROR_URL ?= "file:///mnt/downloads/"
INHERIT += "own-mirrors"
# Use this when generating the mirror:
#BB_GENERATE_MIRROR_TARBALLS = "1"
# Use this to test the mirror:
#BB_NO_NETWORK = "1"

Prepare the source mirror

Add the following line to local.conf:

BB_GENERATE_MIRROR_TARBALLS = "1"

Then run the following to perform every fetch task needed to build the target (in this case, core-image-minimal). Note that this step is version dependent. The change is sumarized here.

# Prior to Yocto 2.4:
bitbake core-image-minimal -c fetchall
# Yocto 2.5 and later:
bitbake core-image-minimal --runall="fetch"

Copy the resulting files into the directory you would like as the source mirror.

cp -t /mnt/downloads/ /tmp/workdir/build/downloads/*

bitbake v2.5 usage and syntax

bitbake -h
...
       --runall=RUNALL       Run the specified task for any recipe in the taskgraph
                             of the specified target (even if it wouldn't otherwise
                             have run).
       --runonly=RUNONLY     Run only the specified task within the taskgraph of
                             the specified targets (and any task dependencies those
                             tasks may have).
