Run-time support for Arm AArch32 Processors

This library implements a simple Arm vector table, suitable for getting into a Rust application running in System Mode. It also provides a reference start up method. Some Arm AArch32 based systems will require chip specific start-up code, so the start-up method can be overridden. It should be suitable 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.

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).
