Bare-metal Rust on Zynq-7000

Supported features:

  • Clocking setup
  • UART
  • SDRAM setup
  • Ethernet with smoltcp and async-await on TCP sockets
  • SD card
  • PL programming and startup
  • Pure Rust SZL first-stage bootloader, with SD boot and netboot
  • Control of second CPU core and message passing, with async-await support

Supported boards:

  • Kasli-SoC
  • ZC706
  • Red Pitaya
  • Cora Z7-10 (seems to also run on Cora Z7-07S, including dual-core support)

Build

Zynq-rs is packaged using the Nix 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).

You can build SZL or experiments crate for the platform of your choice by using nix build command, e.g.

nix build .#coraz7-experiments

Alternatively, you can still use cargo xbuild within nix develop shell.

nix develop
cargo xbuild --release -p experiments

Currently the ELF output is placed at target/armv7-none-eabihf/release/experiments, or result/experiments.elf for Nix Flakes build.

Debug

Running on the ZC706

nix develop
cargo xbuild --release -p experiments
cd openocd
openocd -f zc706.cfg

Running on the Cora Z7-10

nix develop
cargo xbuild --release -p experiments --no-default-features --features=target_coraz7
cd openocd
openocd -f cora-z7-10.cfg

Loading a bitstream into volatile memory

openocd -f zc706.cfg -c "pld load 0 blinker_migen.bit; exit"
