To get the whole BSP, you have to use the repo utility.
To install repo:
$: mkdir ~/bin
$: curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$: chmod a+x ~/bin/repo
To download the BSP source:
$: PATH=${PATH}:~/bin
$: mkdir via-vab820-bsp
$: cd via-vab820-bsp
$: repo init -u https://github.com/viaembedded/via-vab820-bsp-platform -b dora
$: repo sync
At the end of this process, you will have all the metadata to start to work with.
$: source ./setup-environment build
$: bitbake via-image-x11
You can use any directory on your host computer to be the build directory (just replace
build above with your desired path).
