//! This test runs a basic application for thumb targets, using the cortex-m crate.
|
|
//!
|
|
//! These targets are very bare-metal: the first instruction the core runs on
|
|
//! power-on is already user code. The cortex-m-rt has to initialize the stack, .data,
|
|
//! .bss, enable the FPU if present, etc.
|
|
//!
|
|
//! This test builds and runs the applications for various thumb targets using qemu.
|
|
//!
|
|
//! How to run this
|
|
//! $ ./x.py clean
|
|
//! $ ./x.py test --target thumbv6m-none-eabi,thumbv7m-none-eabi tests/run-make
|
|
//!
|
|
//! For supported targets, see `example/.cargo/config.toml`
|
|
//!
|
|
//! FIXME: https://github.com/rust-lang/rust/issues/128733 this test uses external
|
|
//! dependencies, and needs an active internet connection
|
|
//!
|
|
//! FIXME: https://github.com/rust-lang/rust/issues/128734 extract bootstrap cargo
|
|
//! to a proper command
|
|
|
|
//@ only-thumb
