Rust on Arm Cortex-R and Cortex-A

This repository provides support for:

• Armv7-R Processors, like the Arm Cortex-R5
• Armv8-R AArch32 Processors, like the Arm Cortex-R52
• Armv7-A Processors, like the Arm Cortex-A5
• Armv8-A AArch32 Processors, like the Arm Cortex-A53 running in 32-bit mode

These libraries were originally written by Ferrous Systems, and are based on the cortex-m libraries from the Rust Embedded Devices Working Group.

There are currently five libraries here:

• cortex-ar - support library for Cortex-R and Cortex-A CPUs (like cortex-m)
• cortex-r-rt - run-time library for Cortex-R CPUs (like cortex-m-rt)
• cortex-a-rt - run-time library for Cortex-A CPUs (like cortex-m-rt)
• arm-targets - a helper library for your build.rs that sets various --cfg flags according to the current target
• cortex-ar-rt-macros - macros for cortex-a-rt and cortex-r-rt (this is an implementation detail - do not use this crate directly)

There are also example programs for QEMU in the examples folder.
