Requirements

These targets are cross-compiled. They have no special requirements for the host.

Support for the standard library is work-in-progress. It is expected that they will support alloc with the default allocator, and partially support std.

Trusty uses the ELF file format.

Building the target

The targets can be built by enabling them for a rustc build, for example:

[build]
build-stage = 1
target = ["aarch64-unknown-trusty", "armv7-unknown-trusty"]

Building Rust programs

There is currently no supported way to build a Trusty app with Cargo. You can follow the Trusty build instructions to build the Trusty kernel along with any Rust apps that are setup in the project.

Testing

See the Trusty build instructions for information on how to build Rust code within the main Trusty project. The main project also includes infrastructure for testing Rust applications within a QEMU emulator.

Cross-compilation toolchains and C code

See the Trusty build instructions for information on how C code is built within Trusty.
