Setup Shared Yocto Cache - Qualcomm Dragonwing Documentation

By default, BitBake creates the sstate-cache and downloads directories inside the build directory. To speed up builds and reuse previously fetched sources and build artifacts across multiple workspaces, you can configure shared locations for these directories.

Export SSTATE_DIR and DL_DIR variables in your shell before running the build commands.

export DL_DIR="/path/to/shared/downloads"
export SSTATE_DIR="/path/to/shared/sstate"
