My device crashed in the field. How do I figure out why?

Embedded systems often crash in the field, leaving developers with nothing more than a disconnected device and zero visibility into the cause. When traditional debugging is impossible, coredumps provide the essential post-mortem data required to reconstruct the system’s final moments. Learn how to configure Zephyr RTOS and the Spotflow SDK to automatically capture, store, and analyze critical crash information—including stack traces, CPU registers, and variable states—remotely. Mastering this workflow allows you to diagnose and resolve elusive firmware faults long after a device has rebooted, transforming your remote debugging capabilities.
