and is built in recent Tow-Boot (no prebuilt releases at this time).
## Image build
> **NOTE**: These images will be built without a *Platform Firmware*.
### SD image
```
$ nix-build -A sdImage
```
### ISO image
```
$ nix-build -A isoImage
```
## Note about cross-compilation
This will automatically detect the need for cross-compiling or not.
When cross-compiled, all caveats apply. Here this mainly means that the kernel
will need to be re-compiled on the device on the first nixos-rebuild switch,
while most other packages can be fetched from the cache.
For cross-compilation, you might have to provide a path to a known-good Nixpkgs
checkout. *(Left as an exercis to the reader.)*
```
$ NIX_PATH=nixpkgs=/path/to/known/working/cross-compilation-friendly/nixpkgs
```
## *Platform Firmware*
> **NOTE**: The previously available customized *U-Boot* from this repository
