## Building firmware ## Getting the firmware
Once you get your hands on the firmware, you will need to work around few shortcomings of Nix, mainly not being able to run dynamically linked executables. Here is [Mirny 0.3.1 firmware](../extra/mirny/mirny-0.3.1.zip). It contains a single ``.jed`` file that can be flashed following [flashing instructions](#flashing).
### Building firmware (optional)
