 (<http://buildroot.org/downloads/>). However, you can clone an upstream Git repository:

 Upstream Buildroot does not support ARCv3 families. If you are going to build Linux for ARCv3 then
 consider using a separate Synopsys repository with patches for support of ARC HS5x and ARC HS6x:
 
 ```shell
-git clone -b arc-2024.12 https://github.com/foss-for-synopsys-dwc-arc-processors/buildroot
