 1 | # buildroot_flake
 2 | 
 3 | Simple flake builds buildroot projects on nixos.
 4 | 
 5 | Buildroot hardcodes `/usr/bin/` paths, which is why this project uses
 6 | a `FHSuserEnv` instead of a basic `mkShell`.
 7 | 
 8 | The cross toolchain used is `AARCH64` but can be modified for other
 9 | architectures by modifying the `pkgsCross` path to the cross compiling gcc.
