Support for AArch32 Arm Processors
This crate provides access to CPU registers and common peripherals 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.
This crate contains:
- Raw register access to many AArch32 system registers
- A driver for the PMSAv7 Memory Protection Unit (MPU)
- A driver for the PMSAv8-R Memory Protection Unit (MPU)
- A driver for the Arm Generic Timer
If you need a driver for the Arm Generic Interrupt Controller, see https://github.com/ArmFirmwareCrates/arm-gic.
Minimum Supported Rust Version (MSRV)
This crate is guaranteed to compile on stable Rust 1.83.0 and up, as recorded
by the package.rust-version property in Cargo.toml.
Increasing the MSRV is not considered a breaking change and may occur in a
minor version release (e.g. from 0.3.0 to 0.3.1, because this is still a
0.x release).
