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!

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!
