+## Getting the firmware
+
+On Hydra you can find [Mirny 0.3.1 firmware](https://nixbld.m-labs.hk/job/artiq/gluelogic/mirny-cpld-almazny). It contains a single ``.jed`` file that can be flashed following [flashing instructions](#flashing). This firmware supports Almazny v1.2+.
+
+If you are using a legacy Almazny (v1.0-1.1), due to different signals routed, you need to flash the older [0.2.4 firmware with Almazny support](https://nixbld.m-labs.hk/job/artiq/gluelogic/mirny-cpld-legacy-almazny).
+
+### Building firmware (optional)
+
+However, if you need to make chances or build from source, follow these instructions.
+
+Once you get your hands on the firmware source code, 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
+
+For flashing, you will need Xilinx ISE 14.7 installed on your system (here assuming ``/opt/Xilinx`` path), and ``xc3sprog`` with the appropriate HS2 JTAG adapter.
+
+```shell
+nix-shell -p xc3sprog
+xc3sprog -c jtaghs2 -m /opt/Xilinx/14.7/ISE_DS/ISE/xbr/data -v build/mirny.jed

+# Sinara 5716 DAC Shuttler
+
+The Sinara 5716 DAC Shuttler consists of the [Shuttler](https://github.com/sinara-hw/Shuttler), [Remote AFE-Board](https://github.com/sinara-hw/Shuttler), and [EEM FMC Carrier](https://github.com/sinara-hw/EEM_FMC_Carrier) (EFC) Board. 
+
+The EFC Board has an FPGA running Kasli Satellite. DRTIO communication is established through the EEM Cable. At first power up, EFC Board and connected Kasli/Kasli-soc calibrate the clock skews on their own EEM transceiver and then store the value into the flash memory/SD Card.
+
+## JSON
+
+```json
+{
+    "type": "shuttler",
+    "ports": [<port num>]
+}
+```
+
+## Hardware Configurations and Connections
+### EEM Cable Connection 
+
+Only the EEM0 port on the EFC board is used. The EEM Cable provides power. You can ignore the barrel jack at the back of the board if it is placed.
+
+### CLK Input
+
+The EFC requires a **common** clock source with the connected device.
+
+For the EFC Board v1.0, please refer to this [issue](https://github.com/sinara-hw/EEM_FMC_Carrier/issues/44).
+
+For the EFC Board v1.1 (or later), there is a DIP switch to select the clock source.
+![efc_clk_sel](../img/efc_clk_sel.png)
+
+| Clock Source | CLK_SEL0 | CLK_SEL1 |
+|---|---|---|
+| Front Panel SMA | 0 | 0 |
+| Internal Oscillator(default) | 1 | 0 |
+| MMCX | 0 | 1 |
+| PE CLK | 1 | 1 |
+
+### VADJ Power
+
+The EFC Board has configurable Digital IO Voltage Level/PSU called VADJ. You should configure VADJ to 1.8V by fitting W1/W2 jumper accordingly.
+![efc_vadj_settings](../img/efc_vadj_settings.jpg)
+
+
+### Remote AFE Board Connections
+
+The Remote AFE Board is not installed in the crate and should be shipped separately. When you test the EFC Board, please connect the Mini SAS Cables in this orientation.
+![Mini-Sas Connections](../img/shuttler_afe_connections.jpg)
+
+There is no PSU for the Remote AFE Board at this moment. For testing purposes, you should connect the Remote AFE Board to a lab PSU supplying +15V, -15V, and +5V. Please make sure all voltages share a common GND and check the pinouts carefully. Incorrect power connections can damage the Remote AFE Board.                                                  
+
+## Building EFC Board Gateware and Firmware
+
+The EFC Board gateware and firmware are on the [Artiq](https://github.com/m-labs/artiq) repo.
+
+To build the gateware and firmware,
+```
+python -m artiq.gateware.targets.efc --hw-rev [v1.0, v1.1]
+```
+
+## Routing Table Configuration if Shuttler is Connected to Kasli Satellite
+
+When Kasli Satellite is compiled with Shuttler, Shuttler is connected to the Satellite Repeater instance. Therefore, you will need to specify the routing table on the Kasli/Kasli-soc master in order to access the Shuttler hardware. Shuttler locates at DEST 4 connecting to Repeater ID #3. The ID number goes up accordingly if more than one Shuttler is connected.
+
+Here provides an example to configure the routing table.
+You have 1 Kasli Master and 1 Kasli Satellite. Kasli Master (SFP1)(DEST1) port is connected to Kasli Satellite(SFP0)(DEST0). Shuttler is connected to Kasli Satellite with DRTIO over EEM Cable(DEST4).
+
+1. Initialize the Routing Table: ``` artiq_route rt.bin init```
+2. Add the routing table entry for Kasli Master's Peripherals: ```artiq_route rt.bin set 0 0```
+3. Add the routing table entry for Kasli Satellite's Peripherals: ```artiq_route rt.bin set 1 1 0```
+4. Add the routing table entry for Shuttler: ```artiq_route rt.bin set 4 1 4 0```
+5. Flash the routing table on Kasli Master: ```artiq_coremgmt config write -f routing_table rt.bin```
+
+## Flashing
+
+When you are building a crate with shuttler(s), you should erase the flash/sd card config on both the EFC and Kasli/Kasli-soc. Always flash the EFC Board first before flashing the Kasli/Kasli-soc.
+
+If either of the following elements is changed, you will need to **ERASE** the stored calibrated values on both the EFC and Kasli Master, or the communication between the boards cannot be established:
+1. EEM Cable
+2. Clock-Related Cable
+3. EFC Board Gateware
+4. Kasli/Kasli-Soc Master Gateware
+5. EFC Board/Kasli/Kasli-Soc PCB
+
+To erase the flash on the EFC board,
+```
+artiq_flash -t efc erase
+```
+
+To flash the gateware and firmware onto the EFC board,
+```
+artiq_flash --srcbuild -t [efc1v0, efc1v1] -d artiq_efc/shuttler
+```
+
+## Testing
+
+1. Connect the Remote AFE Card to the Shuttler
+2. Power up the Remote AFE Board and the Kasli/Kasli-Soc with the connected Shuttler.
+3. Check all Remote AFE Board Power Indicator LEDs.

+* ``stabilizer-dual-iir-pounder_v1_0`` supports Pounder 1.0 and 1.1 (legacy),
+* ``stabilizer-lockin`` is a different application which we do not usually flash.
+
+These all include changes to the mainline code to include Pounder telemetry.
+
+### Building (optional)
+
+Please keep in mind that the firmware from the official Quartiq repository does not include support for Pounder in MQTT, you may need to use a fork for that. But if the stabilizer is without a Pounder, it's also a valid option.
+
+There is no Nix Flake support to make things easier, so you need to set up rust and cargo manually. Start with cloning the stabilizer repository and opening a new shell with dfu-util (for flashing) and rustup (for building).
+
+```
+nix-shell -p dfu-util rustup
+```
+
+Set up the toolchain, this should be done only once:
+
+```
+rustup target add thumbv7em-none-eabihf
+cargo install cargo-binutils
+rustup component add llvm-tools-preview
+rustup update
+rustup default stable
+```
+
+Building:
+
+```
+cargo build --release
+cargo objcopy --release --bin dual-iir -- -O binary dual-iir.bin
+```
+
+## Flashing
+
+Once you have the binary, you can now flash it.
+
+Without firmware on the device or with older firmware (without USB serial console), you need to use the jumper method:
+
+1. Have the Stabilizer disconnected from power.
+2. Use a jumper of some sort to short BOOT pins on the board.
+3. Turn on the power.
+4. You can remove the jumper after few seconds.
+
+With newer firmware with USB serial console:
+
+1. Connect the Stabilizer to power.
+2. Connect USB cable to the Stabilizer.
+3. Connect with a serial console emulator, usually at ``/dev/ttyACM0``.
+4. Input ``platform dfu`` in the console.
+
+And for both:
+
+5. The device is now in DFU mode.
+6. Flash the device with the following command:
+
+```
+dfu-util -a 0 -s 0x08000000:leave -R -D dual-iir.bin
+```
+
+7. Look for "File downloaded successfully".
+
+For normal usage, the stabilizer must be configured with USB console later (try ``help`` command first), to set its IP address and MQTT broker address. However, for general testing (like the one below), you don't need to configure it any further.
+
+### Clearing settings
+
+In case someone sets some setting wrongly, or updates the firmware and suddenly there's an incompatibility, you may find (firmware, not yourself) in a state of panic, where it will not allow you to change the settings back.
+
+1. Get into DFU mode (described above), probably with jumper method.
+2. Use dfu-util to clear the flash completely:
+
+```
+dfu-util -a 0 -s 0x08000000:mass-erase:force:leave
+```
+
+3. Reflash the target firmware.

+# AFWS client
+
+This article is intended to help with using the `afws_client` command properly.
+
+## Usage
+
+### What is AFWS
+
+AFWS (ARTIQ FirmWare Service) - a service, that allows building customer tailored firmware and gateware (binaries) on M-Labs's servers, 
+and receive these binaries in ready-to-flash format. Subscription to this service also includes helpdesk support,
+and thus is paid on yearly basis (contact sales for prices). It is also typically included when purchasing Carrier (Kasli/Kasli-SoC) for a year, 
+or one-time when purchasing standalone cards for existing crate. Each variant/carrier requires its own subscription.
+
+### What do I need for obtaining binaries
+
+You'll need to have credentials - username and password, which you can obtain from helpdesk, if you haven't yet. 
+Don't forget to specify variant (sticker on top of the crate) that you need to obtain binaries for.
+
+### When do I need to update
+
+In most cases there is no need to update the firmware, unless you encountered a bug and the fix was backported to your version.
+However, if you: changed the layout of the cards - either moved EEM connections, added or deleted cards; 
+changed modes/configurations of the cards (e.g. enable/disable SUServo, synchronization, edge counter, SED lanes etc.).
+In such cases, these changes need to be authorized through helpdesk.
+
+### How to
+
+The base command looks like this:
+```shell
+afws_client <username> build <afws_directory> <variant>
+```
+
+Where (remove `<` and `>`):
+* `<username>` - your username from credentials
+* `<afws_directory>` - the directory/folder, into which you wish to save the binaries
+* `<variant>` - name of the crate/variant. It's optional if you have only one variant in the account
+
+After running this command, it will ask you for the password (the line will remain blank for security reasons).
+If everything matches (username and password are correct, specified variant is in your account and not expired), 
+AFWS will start building the firmware, which takes 10-15 minutes. Sometimes there might be some problems, in which 
+case don't hesitate to contact helpdesk.
+
+After the build done, the AFWS client will automatically download the binaries into `<afws_directory>`, from which 
+you can flash them into your Carrier.
+
+#### View build logs
+
+You may want to view the build logs (for example, in case of problems with configuration). 
+For this, add `--log` option after build:
+
+```shell
+afws_client <username> build --log <afws_directory> <variant>
+```
+
+#### Specify version
+
+By default, AFWS client tries to figure out the installed ARTIQ version. However it works only for Kasli, and not Kasli-SoC.
+It also may fail to determine ARTIQ version if you are using AFWS client without ARTIQ installation.
+Additionally, you may want to specify version regardless of installed version.
+In all these cases, you'll need to specify **both** `--major-ver` and `--rev` arguments, so your command will look like this:
+
+```shell
+afws_client <username> build --major-ver <MAJOR_VER> --rev <REV> <afws_directory> <variant>
+```
+
+Where:
+* `MAJOR_VER` - ARTIQ major version,  either `7` (legacy), `8` (current stable), 
+  `9` (current beta) or `10` (experimental with `nac3` compiler)
+* `REV` - revision from respective branch and repository - i.e. commit hash. You may obtain it either from:
+  * [ARTIQ repository](https://github.com/m-labs/artiq) (for Kasli 2.0 and earlier) by 
+    [selecting branch](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/managing-branches-in-your-repository/viewing-branches-in-your-repository)
+    and selecting `XXX commits` above list of files. From here, the list of commits in specified branch will appear 
+    and you will be able to choose the commit and press ["Copy full SHA for YYY"](https://docs.github.com/en/pull-requests/committing-changes-to-your-project/creating-and-editing-commits/about-commits#using-the-file-tree) 
+    button in the right side.
+  * [ARTIQ on Zynq repository](https://git.m-labs.hk/M-Labs/artiq-zynq) (for Kasli-SoC). In similar way to GitHub, 
+    you can choose branch, commit history and copy SHA1 of the commit.
+
+The branches currently map as following:
+* ARTIQ-7 - release-7
+* ARTIQ-8 - release-8
+* ARTIQ-9 - master
+* ARTIQ-10 - nac3
+
+The binaries you receive are "pure" - if the inputs are the same (same version,
+same JSON), the system outputs exactly the same binaries, and if you did it recently, they will be obtained from Nix
+cache (i.e. not rebuilt).
+
+#### Change password
+
+After you received credentials from us, we strongly recommend changing the password as soon as possible via 
+`afws_client <username> passwd` command. This command will ask you for existing password and new desired password.
+
+The passwords are stored in a hashed way (i.e. cannot be decrypted back), however it's your responsibility to choose good passwords.
+Just keep in mind, that password may contain only alpha-numeric symbols and underscore `[a-zA-Z0-9_]`.
+If you cannot login, we may reset your password if you email us at helpdesk.
+
+#### Get variants
+
+You may get variants, which are tied to your account by using `get_variants` command:
+```shell
+afws_client <username> get_variants
+```
+
+It will ask for password and output the variants and their respective expiry date:
+
+```text
++-----------+-------------+
+|  Variant  | Expiry date |
++-----------+-------------+
+|   test    |  2028-02-08 |
+|   test3   |  2042-08-08 |
++-----------+-------------+
+```
+
+#### Get JSONs
+
+Sometimes you may want to view the JSON description, from which AFWS is building the variant. With the JSON, you can
+later build the firmware by yourself and/or generate device_db file. The command looks like this (variant 
+needs to be valid, i.e. not expired and authorized in your account):
+
+```shell
+afws_client <username> get_json [-o <OUT>] [-f] <variant>
+```
+
+Specify output file `-o <OUT>`, if you want to save it directly to file `<OUT>`, use `-f` if you want to force 
+overwrite. If you do not specify any of these options, you'll get the JSON description directly in stdin (i.e. in your
+console/terminal).
+
+
+#### Miscellaneous
+
+You may also specify custom AFWS provider with these options (put them before username):
+
+* `--server SERVER` - server to connect to (default: afws.m-labs.hk)
+* `--port PORT` - port to connect to (default: 80)
+* `--cert CERT` - SSL certificate file used to authenticate server (default: use system certificates)

+
+This page describes how to start with ARTIQ system for novice users.
+
+## Connecting wires
+
+In most cases the system is shipped with power bricks (PSU), DC splitters and SFPs enough to power and control the whole system.
+Connect them in following order:
+1. Insert Ethernet SFP into the SFP0 of the master or standalone Kasli/Kasli-SoC (Carrier)
+2. Connect these SFPs to the router or PC via Ethernet cable (in some cases, optical cable)
+3. Insert optic/direct attach SFPs into the master and satellite Carriers, respective to the numeration, [more info in DRTIO page](drtio.md)
+4. Power on PSU or EEM power module, by inserting C14 cable, attach DC splitters if available
+5. Some cards may have "External power" setting (check the quotation), in this case, insert DC connector into the port
+6. Insert remaining cables into the Carriers (not applicable in case of EEM Power Module).
+
+## Set the network
+
+By default standalone/master Carriers arrive with 192.168.1.75/24 set as their static address. Carrier will try to acquire this address
+from your router, and in case of failure, they will be just unavailable from the network. Check the following articles for troubleshooting network issues:
+* [Networking](networking.md)
+* [Official docs](https://m-labs.hk/artiq/manual/installing.html#setting-up-the-core-device-ip-networking)
+
+## Run first experiment via artiq_run
+
+Before diving in to the repository experiments management and scheduling, it is essential to try run your first experiment
+via most basic way - `artiq_run`. For this you need to enter your ARTIQ environment (console) and run:
+```shell
+artiq_run --device-db path/to/device_db.py path/to/experiment.py
+```
+
+In case your directory contains relevant `device_db` file, you may omit the `--device-db path/to/device_db.py` part.
+To check this, you may run `ls .` and check if it is in the list.
+
+On pre-installed NUCs, the ARTIQ commands are available everywhere, and you just need to run them.
+If you have Nix package manager or NixOS, you will just need to enter the shell with `nix develop github:m-labs/artiq\?ref=release-7`.
+If you have installed ARTIQ with Conda, you will need to activate the environment with `conda activate <name of the environment with ARTIQ>`.
+
+You may check for experiments in the [official docs](https://m-labs.hk/artiq/manual/getting_started_core.html).

+3. Add following into the `~/.local/share/nix/trusted-settings.json`, by `mkdir -p ~/.local/share/nix/ && nano ~/.local/share/nix/trusted-settings.json` 
+   or with your favorite way (don't forget to save - Ctrl+O in `nano`):
+    ```json
+    {
+       "extra-sandbox-paths":{
+          "/opt":true
+       },
+       "extra-substituters":{
+          "https://nixbld.m-labs.hk":true
+       },
+       "extra-trusted-public-keys":{
+          "nixbld.m-labs.hk-1:5aSRVA5b320xbNvu30tqxVPXpld73bhtOeH6uAjRyHc=":true
+       }
+    }
+    ```
+4. Enable flakes in Nix and add `/opt` to sandbox e.g. adding following to the `nix.conf` (for example `~/.config/nix/nix.conf` or `/etc/nix/nix.conf`):
+    ```
+    experimental-features = nix-command flakes
+    extra-sandbox-paths = /opt
+    ```
+5. On Ubuntu, the Nix will conflict with Apparmor. You'll need to disable Apparmor for Nix, 
+   or for the whole system (you can also delete Apparmor completely, but be careful with it).
+
+From here, you should be able to enter ARTIQ development shell directly from URL, or by cloning the repository.
+The later will allow you to edit the source code in case of need.
+
+For example for Kasli 2.0:
+
+```shell
+git clone https://github.com/m-labs/artiq.git
+cd artiq
+nix develop #boards
+```
+
+For Kasli-SoC:
+```shell
+git clone https://git.m-labs.hk/M-Labs/artiq-zynq.git
+cd artiq-zynq
+nix develop
+```
+
+For building instructions for your JSON, please refer to the [build and test instructions](../build_test_firmware.md).
+The reference uses commands like `nix develop github:m-labs/artiq\?ref=release-8#boards` and `nix develop git+https://git.m-labs.hk/m-labs/artiq-zynq\?ref=release-8`.
+You may safely skip such commands if you entered the development shell (`nix develop`) from cloned git repository.
+
+If you want to update the source files, you may use `git pull origin master --rebase`. 
+Please refer to the [git documentation](https://www.git-scm.com/docs) or other resources of your choice if you are unfamiliar with `git`. 
+You may also use GUI git tools, like the one integrated into JetBrains IDEs (PyCharm, Intellij and others), VS Code, Sublime Merge or others.
