# `aarch64-unknown-trusty` and `armv7-unknown-trusty`
|
||||
|
||||
**Tier: 3**
|
||||
|
||||
[Trusty] is a secure Operating System that provides a Trusted Execution
|
||||
Environment (TEE) for Android.
|
||||
|
||||
## Target maintainers
|
||||
|
||||
- Nicole LeGare (@randomPoison)
|
||||
- Stephen Crane (@rinon)
|
||||
- As a fallback trusty-dev-team@google.com can be contacted
|
||||
|
||||
## Requirements
|
||||
|
||||
This target is cross-compiled. It has no special requirements for the host.
|
||||
|
||||
It fully supports alloc with the default allocator, and partially supports std.
|
||||
Notably, most I/O functionality is not supported, e.g. filesystem support and
|
||||
networking support are not present and any APIs that rely on them will panic at
|
||||
runtime.
|
||||
|
||||
Trusty uses the ELF file format.
|
||||
|
||||
## Building the target
|
||||
|
||||
The targets can be built by enabling them for a `rustc` build, for example:
|
||||
|
||||
```toml
|
||||
[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.
