## Building 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.
|
||||||
|
|
||||||
|
You will need:
|
||||||
|
- Xilinx ISE 14.7 installed on your system (this guide is assuming ``/opt/Xilinx`` path),
|
||||||
|
- an environment with Migen.
|
||||||
|
|
||||||
|
One way to do it is to create an FHS environment, like ARTIQ does for Vivado, within ARTIQ's ``flake.nix`` (to leverage Migen already being there), by adding these lines:
|
||||||
|
|
||||||
|
```
|
||||||
|
iseEnv = pkgs.buildFHSEnv {
|
||||||
|
name = "ise-env";
|
||||||
|
targetPkgs = vivadoDeps;
|
||||||
|
};
|
||||||
|
|
||||||
|
ise = pkgs.buildFHSEnv {
|
||||||
|
name = "ise";
|
||||||
|
targetPkgs = vivadoDeps;
|
||||||
|
profile = "set -e; source /opt/Xilinx/14.7/ISE_DS/settings64.sh";
|
||||||
|
runScript = "ise";
|
||||||
|
};
|
||||||
|
```
|
||||||
|
|
||||||
|
Add them below ``vivadoEnv``. Then add ``iseEnv`` and ``ise`` to the dev shell's build inputs. Call ``nix develop`` on that.
|
||||||
|
|
||||||
|
Then you can build Mirny:
|
||||||
|
|
||||||
|
```shell
|
||||||
|
nix develop
|
||||||
|
ise-env
|
||||||
|
cd ../mirny # or wherever your source is at
|
||||||
|
source /opt/Xilinx/14.7/ISE_DS/settings64.sh
|
||||||
|
python mirny_impl.py
|
||||||
|
```
|
||||||
|
|
||||||
|
### Flashing
|
||||||
|
|
||||||
|
```shell
|
||||||
|
nix-shell -p xc3sprog
|
||||||
|
xc3sprog -c jtaghs2 -m /opt/Xilinx/14.7/ISE_DS/ISE/xbr/data -v build/mirny.jed
|
||||||
|
```

~~Mirnies often fail `ValueError: MUXOUT not high`, in that case restart the tests or reboot the board(s).~~ - fixed in [9569cfb](https://github.com/m-labs/artiq/commit/9569cfb26329c0acdc1705d3256d2506b7bccce5)

For Almazny v1.2+ support, CPLD firmware above 0.3.0 (with fixes) must be flashed onto Mirny.
