Here are the lines in our local.conf that make it work. If you want you can
use a local http mirror instead of file.
DL_DIR ?= ${TOPDIR}/tmp/downloads-keepout
SSTATE_DIR ?= ${TOPDIR}/sstate-cache
# we build on isolated network, so disable all network access
#don't really disable all network,
We do offline builds. You need to download all the tar balls for all the open
source recipes you build, or you can download pre-build images and SDK.
Another way is to create a local mirror of all the tar balls you need.
