Note: this repository uses git lfs so be sure the machine you are cloning this repository to supports git lfs.

Set up git lfs

• 0). Do not clone this repository if git lfs is not set up yet. Otherwise, the file gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu.tar.xz won't be checked out.
• 1). Open Git Large File Storage (LFS).
• 2). Click Install v3.3.0 via PackageCloud (Linux).
• 3). Use the step in quick install. Note that this only sets up the Debian APT respository and doesn't actually install the git-lfs package.
• 4). Once the script says "The repository is setup! You can now install packages.", run sudo apt-get install git-lfs according to git-lfs/git-lfs/wiki/Installation.
• 5). Then git lfs install.
