panic-rtt-target
Logs panic messages over RTT. A companion crate for rtt-target.
Documentation
RTT must have been initialized by using one of the rtt_init
macros. Otherwise you will get a linker error at compile time.
Panics are always logged on channel 0. Upon panicking the channel mode is also automatically set to BlockIfFull
, so that the full message will always be logged. If the code somehow manages to panic at runtime before RTT is initialized (quite unlikely), or if channel 0 doesn't exist, nothing is logged.
A platform feature such as cortex-m
is required to use this crate.
Usage
Cargo.toml:
[]
= { = "x.y.z", = ["cortex-m"] }
main.rs:
use panic_rtt_target as _;
use rtt_init_default;
!
