cortex-a
Low level access to Cortex-A processors.
Currently Supported Execution States
- AArch64
- AArch32
Minimum Supported Rust Version
Requires a recent nightly of Rust.
Usage
Please note that for using this crate's register definitions (as provided by
cortex_a::registers::*
), you need to also include
tock-registers
in your project. This is because the
interface
traits provided by tock-registers
are implemented by this crate. You should include
the same version of tock-registers
as is being used by this crate to ensure sane
interoperatbility.
For example, in the following snippet, X.Y.Z
should be the same version of tock-registers
that
is mentioned in cortex-a
's Cargo.toml
.
[]
= "Your embedded project"
# Some parts omitted for brevity.
[]
= "X.Y.Z"
= "A.B.C" # <-- Includes tock-registers itself.
Example
Check out https://github.com/rust-embedded/rust-raspberrypi-OS-tutorials for usage examples. Listed
below is a snippet of rust-raspberrypi-OS-tutorials
's early boot code.
use ;
use Writeable; // <-- Trait needed to use `write()` and `set()`.
// Some parts omitted for brevity.
