David Nadlinger 2ddb4d259f Undo most of Si5324 unification (5c054cc901)
This reverts most of 5c054cc901, as it turns out that
si5324::setup is in fact also used to configure the
chip for operation as a DRTIO satellite.
2022-12-17 01:31:14 +00:00
David Nadlinger 5c054cc901 Unify Si5324 setup code with main ARTIQ repository [nfc]
I chose the version from the main repository for two
reasons:
 - Explicitly specifying si5324_ref_input every time would
   not work for the different Kasli/… hardware versions.
 - Having `crystal_ref` as a setting in the configuration
   is misleading if it does not actually activate the crystal
   for use as a reference (but rather does
   `route_crystal_to_ckin2`).

mwojcik c834e4f503 enable network and mgmt during Rust panic, make RTIO PLL lock failure a panic
Closes #198 #200

Making it a soft panic makes it more involved with a bit of code duplication - setting up mgmt requires setting up the interface and sockets. Maybe can be done a bit cleaner.

How to use
----------
1. Install ARTIQ-6 or newer.
2. Select the latest successful build on Hydra: https://nixbld.m-labs.hk/jobset/artiq/zynq
3. Search for the job named ``<board>-<variant>-sd`` (for example: ``zc706-nist_clock-sd`` or ``zc706-nist_qc2-sd``).
4. Download the ``boot.bin`` "binary distribution" and place it at the root of a FAT-formatted SD card.
5. Optionally, create a ``config.txt`` configuration file at the root of the SD card containing ``key=value`` pairs on each line. Use the ``ip``, ``ip6`` and ``mac`` keys to respectively set the IPv4, IPv6 and MAC address of the board. Configuring an IPv6 address is entirely optional. If these keys are not found, the firmware will use default values that may or may not be compatible with your network.
6. Insert the SD card into the board and set up the board to boot from the SD card. For the ZC706, this is achieved by placing the large DIP switch SW11 in the 00110 position.
7. Power up the board. After the firmware starts successfully, it should respond to ping at its IP addresses, and boot messages can be observed from its UART at 115200bps.
8. Create and use an ARTIQ device database as usual, but set ``"target": "cortexa9"`` in the arguments of the core device.
1. [Install ARTIQ](https://m-labs.hk/artiq/manual/installing.html). Get the corresponding version to the ``artiq-zynq`` version you are targeting.
2. To obtain firmware binaries, use AFWS or build your own; see [the ARTIQ manual](https://m-labs.hk/artiq/manual/building_developing.html) for detailed instructions or skip to "Development" below. ZC706 variants only can also be downloaded from latest successful build on [Hydra](https://nixbld.m-labs.hk/).
3. Place ``boot.bin`` file at the root ``/`` of a FAT-formatted SD card.
4. Optionally, create a ``config.txt`` configuration file containing ``key=value`` pairs on each line and place it at the root of the SD card. See below for valid keys. The ``ip``, ``ip6`` and ``mac`` keys can be used to set networking information. If these keys are not found, the firmware will use default values which may or may not be compatible with your network.
5. Insert the SD card into the board and set the board to boot from the SD card. For ZC706, this is achieved by placing the large DIP switch SW11 into the 00110 position. On Kasli-SoC, place the BOOT MODE switches to SD.
6. Power up the board. After successful boot the firmware should respond to ping at its IP addresses. Boot output can be observed from UART at 115200bps 8-N-1.
7. Create and use an ARTIQ device database as usual.
Configuration
-------------
Configuring the device is done using the ``config.txt`` text file at the root of the SD card, plus the contents of the ``config`` folder. When searching for a configuration key, the firmware first looks for a file named ``/config/[key].bin`` and, if it exists, returns the contents of that file. If not, it looks into ``/config.txt``, which contains a list of ``key=value`` pairs, one per line. The ``config`` folder allows configuration values that consist in binary data, such as the startup kernel.

The following configuration keys are available:
The following configuration keys are available among others:
- ``mac``: Ethernet MAC address.
- ``ip``: IPv4 address.
- ``ip6``: IPv6 address.
- ``startup``: startup kernel in ELF format (as produced by ``artiq_compile``).
- ``idle_kernel``: idle kernel in ELF format (as produced by ``artiq_compile``).
- ``startup_kernel``: startup kernel in ELF format (as produced by ``artiq_compile``).
- ``rtio_clock``: source of RTIO clock; valid values are ``ext0_bypass`` and ``int_125``.
- ``boot``: SD card "boot.bin" file, for replacing the boot firmware/gateware. Write only.
Configurations can be read/written/removed via ``artiq_coremgmt``. Config erase is
not implemented as it seems not very useful.
See [ARTIQ manual](https://m-labs.hk/artiq/manual-beta/core_device.html#configuration-storage) for full list. Configurations can be read/written/removed with ``artiq_coremgmt``. Config erase is not implemented, as it isn't particularly useful.
For convenience, the ``boot`` key can be used with ``artiq_coremgmt`` and a ``boot.bin`` file to replace firmware/gateware in a running system. This key is read-only. When loading ``boot.bin`` onto the SD card directly, place it at the root and not in the ``config`` folder.

nix build .#zc706-nist_clock-jtag # or zc706-nist_qc2-jtag or zc706-nist_clock-sd or etc
```
Impure incremental build and execution on a remote JTAG server:
Run ``nix flake show`` to see all valid build targets. Targets suffixed with ``-jtag`` produce separate firmware and gateware files, intended for use in booting via JTAG server/Ethernet, e.g. ``./remote_run.sh -i`` with a remote JTAG server. Targets suffixed with ``-sd`` will produce ``boot.bin`` file suitable for SD card boot. ``-firmware`` and ``-gateware`` respectively build firmware and gateware only.
The Kasli-SoC target requires a system description file as input. See ARTIQ manual for exact instructions or use incremental build.
**Impure incremental build:**
For boards with fixed variants, i.e. ZC706, etc. :
```shell
nix develop
cd src
gateware/zc706.py -g ../build/gateware -V <variant> # build gateware
make GWARGS="-V <variant>" <runtime/satman> # build firmware
cd ..
./remote_run.sh -i
gateware/<board>.py -g ../build/gateware -V <variant> # gateware
make GWARGS="-V <variant>" <runtime/satman> # firmware
```
For boards with system descriptions, i.e. Kasli-SoC, etc. :
```shell
nix develop
cd src
gateware/<board>.py -g ../build/gateware <description.json> # gateware
make TARGET=<board> GWARGS="path/to/description.json" <runtime/satman> # firmware
```
``szl.elf`` can be obtained with:
```shell
nix build git+https://git.m-labs.hk/m-labs/zynq-rs#<board>-szl
```
To generate ``boot.bin`` use ``mkbootimage``, e.g.:
```shell
echo "the_ROM_image:
{
[bootloader]result/szl.elf
gateware/top.bit
firmware/armv7-none-eabihf/release/<runtime/satman>
}
EOF" >> boot.bif
mkbootimage boot.bif boot.bin
```
Notes:
- 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 ``flake.lock`` in sync.
- If the board is connected to the local machine by JTAG, use the ``local_run.sh`` script.
- A known Xilinx hardware bug prevents repeatedly loading the bootloader over JTAG without a POR reset. If booting over JTAG, install a jumper on ``PS_POR_B`` and use the POR reset script [here](https://git.m-labs.hk/M-Labs/zynq-rs/src/branch/master/kasli_soc_por.py).
Pre-Commit Hooks
----------------
You are strongly recommended to use the provided pre-commit hooks to automatically reformat files and check for non-optimal Rust/C/C++ practices. Run `pre-commit install` to install the hook and `pre-commit` will automatically run `cargo fmt`, `cargo clippy`, and `clang-format` for you.
Several things to note:
- If `cargo fmt`, `cargo clippy`, or `clang-format` returns an error, the pre-commit hook will fail. You should fix all errors before trying to commit again.
- If `cargo fmt` or `clang-format` reformats some files, the pre-commit hook will also fail. You should review the changes and, if satisfied, try to commit again.
