# NixOS on RISC-V
This repository contains NixOS configurations for different RISC-V machines.
## QEMU
To boot the system in QEMU, first enter the development shell:
```
$ nix develop
```
Then run the boot script:
```
$ ./boot.sh
```
To prevent the GC from erasing the system:
```
$ nix build .#devShells.x86_64-linux.default --out-link result-env
```
## FPGA
```
. fpga/env.sh
fpga/fpgactl -w /path/to/bitstream -b openpiton2.bin -k kernel-nixos -r initrd-nixos
```
