Details ❤️ Sponsor

    This is the 22th changelog for Knurling-rs, our push to sustainably build better tooling for developing and debugging Rust software for embedded systems. Knurling-rs includes a suite of tools that make it easier to develop, log, debug, and test your embedded Rust libraries and applications!

    Knurling-rs is supported by our sponsors on GitHub. If you're interested in seeing more projects like this, consider becoming a sponsor today!

    Highlights 🎉

    probe-run --max-backtrace-len

    Our first highlight of today is the new --max-backtrace-len command line option. You are now able to limit the backtrace length, with a default of 50.

    This will look like following: $ probe-run --max-backtrace-len=3 --chip nRF52840_xxAA rtc_async.elf (HOST) INFO flashing program (11.52 KiB) (HOST) INFO success! ──────────────────────────────────────────────────────────────────────────────── 0 INFO Hello World! └─ rtc_async::__cortex_m_rt_main @ /src/bin/ 1 INFO tick └─ rtc_async::run2::task::{{closure}} @ /src/bin/ 2 INFO BIG INFREQUENT TICK └─ rtc_async::run1::task::{{closure}} @ /src/bin/ 3 INFO tick └─ rtc_async::run2::task::{{closure}} @ /src/bin/ 4 INFO tick └─ rtc_async::run2::task::{{closure}} @ /src/bin/ 5 INFO tick └─ rtc_async::run2::task::{{closure}} @ /src/bin/ 6 INFO tick └─ rtc_async::run2::task::{{closure}} @ /src/bin/ ──────────────────────────────────────────────────────────────────────────────── stack backtrace: 0: HardFaultTrampoline <exception entry> 1: rtc_async::run1::task::{{closure}} at /src/bin/ 2: <core::future::from_generator::GenFuture<T> as core::future::future::Future>::poll at /.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/library/core/src/future/ 3: embassy::executor::Task<F>::poll at /src/executor/ (HOST) WARN Maximum backtrace length of 3 reached; cutting off the rest note: re-run with `--max-backtrace-len=<your maximum>` to extend this limit (HOST) ERROR the program panicked

    Shoutout to @antvangelder

    The second highlight is antoinevg/hello-nucleo-h7xx. @antvangelder created a rust starter project for the STMicroelectronics Nucleo-H745ZI-Q board. They based this on our app-template.

    Thank you for this contribution to the embedded rust community!
