Rust Pitaya

Minimalist bare metal Rust firmware for Red Pitaya.

Development instructions

Pure build with Nix and execution on a remote JTAG server:

nix build .#rust-pitaya-jtag
./remote_run.sh

Impure incremental build and execution on a remote JTAG server:

nix develop
cd src
gateware/rust-pitaya.py -g ../build/gateware  # build gateware
make                                          # build firmware
cd ..
./remote_run.sh -i

Notes:

  • The impure build process is also compatible with non-Nix systems.
  • If the board is connected to the local machine, use the local_run.sh script.
  • Due to questionable Zynq design decisions, JTAG boot works only once per power cycle. A good workaround is to power the Red Pitaya through a uhubctl-compatible USB hub and boot with a command such as: ssh rpi-3.m-labs.hk "uhubctl -a off -p 4; sleep 2; uhubctl -a on -p 4; sleep 2" && ./remote_run.sh -i
