portenta-h7

ci

portenta-h7 provides examples for the Arduino Portenta-H7 board written in Rust. The entry point address for the application is located at 0x08040000 to which the Arduino bootloader jumps. The software can be flashed on the target either with USB (DFU), or with a debug probe (JLink, ST-Link). Flashing with Arduino IDE is not supported.

Installation

Unix-like OS

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
rustup target add thumbv7em-none-eabihf
cargo install cargo-embed cargo-binutils

Mac OSX

Installing on MacOSX is slightly different. The easiest way to install rust on OSX is using HomeBrew.

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Installing rustup is preferred over installing rust:

brew install rustup

The brew formula will install rustup-init. Execute rust-init and select 1 to install rust. Next add the following:

rustup target add thumbv7em-none-eabihf
rustup component add llvm-tools-preview

cargo install cargo-embed cargo-binutils

Install the tool for flashing the target:

brew install dfu-util

The installation is complete!

Build

To build an example, run the following command:

cargo <example_name> [--release]

For instance, to build blinky:

cargo blinky

Flash with DFU (USB)

  1. If not already, install dfu-utils on your system.
  2. Connect USB to Portenta.
  3. Set the Portenta in bootloader mode by pressing the reset button twice.
  4. Generate the target binary by running the following command: 
    cargo <example_name>-bin
    For example, to generate the target binary for blinky, run the following command: 
    cargo blinky-bin
  5. Flash the binary to the target by running the following command: 
    dfu-util -a 0 -d 2341:035b --dfuse-address=0x08040000:leave -D <binary_path>
    For example, to flash blinky, run the following command: 
    dfu-util -a 0 -d 2341:035b --dfuse-address=0x08040000:leave -D target/thumbv7em-none-eabihf/release/examples/blinky.bin

Flash with debug probe (JLink, ST-Link)

  1. Connect the probe to the JTAG port of the breakout board.
  2. Run the following command: 
    cargo  <example_name>-probe [--release]
    For example, to flash blinky, run the following command: 
    cargo blinky-probe
