This repository provides support for:
- Legacy Arm Processors, like the ARM7TDMI and ARM926
- 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
It does not support any M-Profile Processors (like the Arm Cortex-M3) as they have a fundamentally different interrupt vector table.
It also does not support processors running in AArch64 mode - A64 machine code uses different instructions for reading/writing system registers.
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:
- aarch32 - support library for AArch32 CPUs (like the cortex-m crate)
- aarch32-rt - run-time library for AArch32 CPUs (like the cortex-m-rt crate)
- arm-targets - a helper library for your build.rs that sets various
--cfgflags according to the current target - aarch32-rt-macros - macros for
aarch32-rt(this is an implementation detail - do not use this crate directly)
There are also example programs for QEMU in the examples folder.
