Fixes #84 using the first solution. If the performance is considered too slow, we can do the second option later.

ARTIQ on Zynq
How to use
- Install ARTIQ-6 or newer.
- Select the latest successful build on Hydra: https://nixbld.m-labs.hk/jobset/artiq/zynq
- Search for the job named
- Download the
boot.bin"binary distribution" and place it at the root of a FAT-formatted SD card.
- Optionally, create a
config.txtconfiguration file at the root of the SD card containing
key=valuepairs on each line. Use the
mackeys 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.
- 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.
- 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.
- Create and use an ARTIQ device database as usual, but set
"target": "cortexa9"in the arguments of the core device.
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:
mac: Ethernet MAC address.
ip: IPv4 address.
ip6: IPv6 address.
startup: startup kernel in ELF format (as produced by
rtioclk: source of RTIO clock; valid values are
Configure Nix channels:
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
Pure build with Nix and execution on a remote JTAG server:
nix-build -A zc706-simple-jtag # or zc706-nist_qc2-jtag or zc706-nist_clock-jtag ./remote_run.sh
Impure incremental build and execution on a remote JTAG server:
nix-shell cd src gateware/zc706.py -g ../build/gateware # build gateware make # build firmware cd .. ./remote_run.sh -i
- This is known to work with Nixpkgs 20.03 and the
nixbld.m-labs.hkbinary 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.
- If the board is connected to the local machine, use the
