He presents some real-world examples that he's faced over the years that will help with any MCU your device is built on.   **You'll learn** - How to recover the stack trace leading up to a fault - MCU registers to examine when root causing a fault - How to quickly pinpoint the source of memory corruption bugs - How to leverage GDB to speed up root cause analysis - How to automate coredump collection, offloading, and processing ## Speaker ![Chris\_Coleman\_Headshot](https://go.memfault.com/hubfs/Chris_Coleman_Headshot.jpg "Chris_Coleman_Headshot") ## Chris Coleman Co-Founder / CTO, Memfault Prior to founding Memfault, Chris was an embedded software engineer at Pebble and Fitbit where he led efforts across the firmware stack and developed a reputation for tracking down and fixing challenging firmware bugs. That coupled with his passion for using tooling to efficiently deliver high-quality hardware products drove him to start Memfault. Chris graduated with a BSc in Electrical Engineering from Brown University. ### Request Demo [![memfault-logo-footer](https://go.memfault.com/hubfs/memfault-logo-footer.svg "memfault-logo-footer")](https://memfault.com/) ### Subscribe for company updates below. - Product - [Performance Monitoring](https://memfault.com/iot-device-monitoring/) - [Device Debugging](https://memfault.com/remote-debugging/) - [OTA Updates](https://memfault.com/ota-firmware-updates/) - [Product Analytics](https://memfault.com/iot-product-analytics/) - [Log Management & Analytics](https://memfault.com/log-management/) - Resources - [Docs](https://docs.memfault.com/) - [Webinars](https://memfault.com/webinars/) - [Case Studies](https://memfault.com/case-studies/) - [Interrupt Blog](https://interrupt.memfault.com/blog/) - [Memfault Blog](https://memfault.com/blog/) - [Events](https://memfault.com/community/) - [Compliance](https://memfault.com/compliance/) - [Product Updates](https://docs.memfault.com/changelog) - [System Status](https://memfault.statuspage.io/) - Company - [About Us](https://memfault.com/about/) - [Careers](https://memfault.com/careers/) - [Customers](https://memfault.com/customers/) - [News](https://memfault.com/news/) - [Partners](https://memfault.com/news/) - [Security](https://memfault.com/security/) - [Contact Us](https://memfault.com/contact-us/) - Get Started - [Try the SandBox](https://demo.memfault.com/demo/start) - [Book a Demo](https://memfault.com/demo-request/) - [Pricing](https://memfault.com/pricing/) - [Support](https://support.memfault.com/) - [GitHub](https://github.com/memfault) - [Docs](https://docs.memfault.com/) - [Interrupt Community](https://interrupt.memfault.com/) - [Support](https://support.memfault.com/) Copyright © 2023 Memfault Inc. - [Privacy Policy](https://memfault.com/privacy-policy/) - [Terms of Service](https://memfault.com/terms/) - [![twitter](https://go.memfault.com/hubfs/raw_assets/public/Memfault_April2021/images/twitter.svg)](https://twitter.com/memfault) - [![linkedin](https://go.memfault.com/hubfs/raw_assets/public/Memfault_April2021/images/linkedin.svg)](https://www.linkedin.com/company/memfault/) - [![youtube](https://go.memfault.com/hubfs/raw_assets/public/Memfault_April2021/images/youtube.svg)](https://www.youtube.com/channel/UCGHAOw3JpB6zOnwA27dlYcQ) - [![slack](https://go.memfault.com/hubfs/raw_assets/public/Memfault_April2021/images/slack.svg)](https://interrupt-slack.herokuapp.com/) - [![github](https://go.memfault.com/hubfs/raw_assets/public/Memfault_April2021/images/github.svg)](https://github.com/memfault) ```json { "@context" : "https://schema.org", "@type" : "VideoObject", "caption" : { "@type" : "MediaObject", "contentUrl" : "https://go.memfault.com/media-transcripts/45720174451/en.vtt", "inLanguage" : "en", "name" : "en Captions" }, "contentUrl" : "https://8551838.fs1.hubspotusercontent-na1.net/hubfs/8551838/How%20to%20Debug%20HardFaults%20on%20ARM%20Cortex-M%20MCU%20Webinar%20Recording%20with%20Q&A.mp4", "dateModified" : "2025-10-09T15:51:26.876Z", "description" : "In this recorded webinar, learn the most efficient and effective tips for debugging and resolving issues quickly with real-world examples.", "duration" : "PT57M57.183S", "height" : 864, "name" : "How to Debug HardFaults on ARM Cortex-M MCU Webinar Recording", "thumbnailUrl" : "https://go.memfault.com/hubfs/How%20to%20Debug%20HardFaults%20on%20ARM%20Cortex-M%20MCU%20Webinar%20Recording%20with%20Q&A.mp4/medium.jpg", "uploadDate" : "2021-04-22T20:12:26.469Z", "width" : 1760 } ```
