geckoboot.rs

A blinky demo for using the Rust programming language bare metal on EFM32GG_STK3700 Giant Gecko starter kit from Silicon Labs.

This repository is based on https://github.com/neykov/armboot/ and adapted for the Giant Gecko kit.

Requirements:

• arm-none-eabi toolchain
• llvm-3.6 (nightly) toolchain
• rustc (tested on "rustc 1.0.0-nightly (44a287e6 2015-01-08 17:03:40 -0800)")
• Rust libcore compiled for arm (tested at 44a287e6)

Setup:

The rustc command must be available on your path. Add the environment variables SIMPLICITY_STUDIO_HOME and RUST_SRC_HOME pointing to Silicon Labs Simplicity Studio and the Rust Source respectivly. And the arm-gcc-toolchain must be on your path. For the make flash command to work the utility eACommander must be on your path.

Compiling:

make flash PROJ_NAME=<filename> excluding .rs

Structure

• blinky.rs - sample program (blinks LED1 and LED0 on the EFM32GG_STK3700 board)
• buttons.rs - sample program (hooks up PB0 and PB1 with LED0 and LED1 on the EFM32GG_STK3700 board)
• emlib/ - rust bindings for emlib
• emdrv/ - rust bindings for emdrv
