//! Redirecting `panic!` messages
|
|
//!
|
|
//! The `cortex-m-rt` crate provides two options to redirect `panic!` messages
|
|
//! through these two Cargo features:
|
|
//!
|
|
//! - `panic-over-semihosting`. `panic!` messages will be printed to the OpenOCD
|
|
//! console using semihosting. This is slow.
|
|
//!
|
|
//! - `panic-over-itm`. `panic!` messages will be send through the ITM port 0.
|
|
//! This is much faster but requires ITM support on the device.
|
|
//!
|
|
//! If neither of these options is specified then the `panic!` message will be
|
|
//! lost. Note that all `panic!`s will trigger a debugger breakpoint.
|
|
//!
|
|
//! ```
