PROJECT MOVED

This project has been moved to cpdt/trustzone-m-rs: https://gitee.com/cpdt/trustzone-m-rs .

trustzone-m-rs

ARM TrustZone-M example application in Rust, both secure world side and non-secure world side; projects are modified from generated result of cortex-m-quickstart.

This project is based on guide Writing secure applications using Rust and TrustZone-M, Version 1.0 by ARM, (c) 2022 Arm Limited.

Features

This project illustrates how to:

• Write and run TrustZone-M application in Rust
• Enter Non-Secure entry function in Secure World
• Handle secure faults
• Call secure function in Non-Secure World (using veneers.o)
• Check permission in secure functions with pointers

Run

You need to install rustc target, using:

rustup target add thumbv8m.main-none-eabi

Additionally, you should check if your computer have arm-none-eabi-ld installed by arm-none-eabi-ld --version 2. This special ARM linker is used on veneer generation; veneer is an important media where non-secure applications get a list of supported functions provided by secure world side.

Clone repository and run:

git clone git@github.com:IoTS-P/trustzone-m-rs.git
cd trustzone-m-rs
cargo qemu

You'll get the following results:

    Finished dev [unoptimized + debuginfo] target(s) in 0.05s
     Running `target\debug\xtask.exe qemu`
xtask: make application and run in QEMU
    Finished dev [unoptimized + debuginfo] target(s) in 0.04s
    Finished dev [unoptimized + debuginfo] target(s) in 0.04s
