==== Special Devices ====
 
It is possible to emulate a RISC-V platform with QEMU.

==== SD card images (SBCs and similar platforms) ====
* https://github.com/NixOS/nixos-hardware


== Images ==
For <code>riscv64</code> it is possible to download images from the community.

== Binary caches ==
Build or download the image.
 
If the image has the extension <code>.zst</code>, it will need to be decompressed before writing to installation device. Use <code>nix-shell -p zstd --run "unzstd <img-name>.img.zst"</code> to decompress the image.

== Packages ==
== NixOS Support ==
 
All RISC-V platforms are experimental for the time being.
 
There is a dedicated room for the upstream effort on Matrix,
[https://matrix.to/#/#riscv:nixos.org matrix:r/riscv:nixos.org].
