Development instructions
------------------------
Configure Nix channels:
```shell
nix-channel --add https://nixbld.m-labs.hk/channel/custom/artiq/fast-beta/artiq-fast
nix-channel --update
```
Note: if you are using Nix channels the first time, you need to be aware of this bug: https://github.com/NixOS/nix/issues/3831
ARTIQ Zynq is packaged using the [Nix](https://nixos.org) Flakes system. Install Nix 2.4+ and enable flakes by adding ``experimental-features = nix-command flakes`` to ``nix.conf`` (e.g. ``~/.config/nix/nix.conf``).
Pure build with Nix and execution on a remote JTAG server:
```shell
nix-build -A zc706-nist_clock-jtag # or zc706-nist_qc2-jtag or zc706-nist_clock_satellite-jtag etc.
nix build .#zc706-nist_clock-jtag # or zc706-nist_qc2-jtag or zc706-nist_clock_satellite-jtag etc.
./remote_run.sh
```
Impure incremental build and execution on a remote JTAG server:
```shell
nix-shell
nix develop
cd src
gateware/zc706.py -g ../build/gateware -v <variant> # build gateware
make GWARGS="-V <variant>" <runtime/satman> # build firmware

Notes:
- This is developed with Nixpkgs 21.05[^1], and the ``nixbld.m-labs.hk`` binary substituter can also be used here (see the ARTIQ manual for the public key and instructions).
- This is developed with Nixpkgs 21.11, and the ``nixbld.m-labs.hk`` binary substituter can also be used here (see the ARTIQ manual for the public key and instructions).
- The impure build process is also compatible with non-Nix systems.
- When calling make, you need to specify both the variant and firmware type.
- Firmware type must be either ``runtime`` for DRTIO-less or DRTIO master variants, or ``satman`` for DRTIO satellite.
- If the board is connected to the local machine, use the ``local_run.sh`` script.
- To update ``zynq-rs``, update the cargo files as per usual for Rust projects, but also keep ``zynq-rs.nix`` in sync.
[^1]: Thus, on newer version of NixOS, you should run `nix-shell -I nixpkgs=https://github.com/NixOS/nixpkgs/archive/21.05.tar.gz` instead
- To update ``zynq-rs``, update the cargo files as per usual for Rust projects, but also keep ``flake.nix`` in sync.
