This repository shows how to compile a Rust application which runs on FreeRTOS.
freertos-kernelis a git submodule to the FreeRTOS github repofreertos-sysis a Rust library which runs bindgen on the FreeRTOS headers, and compiles the FreeRTOS source for Cortex-M4Fdemo-appis a Rust application which usesfreertos-sys, which runs on the nRF52840DK

└─ demo_app::test_task1 @ src/main.rs:95 FreeRTOS is downloaded in source form using a git submodule. Ensure you have fetched the submodule, e.g. with:
git submodule update --initBecause FreeRTOS is written in C, you will require a C compiler for your target. We compile the C code using the cc crate which does a good job of finding an appropriate C compiler. You can download Arm's build of GCC for arm-none-eabi, or your system package manager might provide gcc-arm-none-eabi or arm-none-eabi-gcc packages.
