fatal: not a git repository (or any of the parent directories): .git
Command ‘[‘git’, ‘describe’, ‘–always’, ‘–tags’, ‘–match=fw’, ‘–dirty=*’]’ returned non-zero exit status 128.
Firmware version 0.0.0-dev ([unknown version])
The firmware build script is trying to use Git to determine its version, but you are not using Git…
As a hack to make it work, you could try git init in the top directory, but you should really be using version control synced with the main repo, i.e. you should have used ‘git clone’ to download the firmware in the first place.
