Firmware on embedded devices can freeze, overload, or behave unpredictably, leaving developers frustrated because traditional debugging tools often miss these issues. Intermittent problems, like a device requiring a power cycle, leave no diagnostic data in RAM, making it hard to understand what went wrong. Timing-related bugs are especially tricky, as standard logs or breakpoints cannot capture missing events.
Percepio Detect 2025.2 tackles these challenges with TaskMonitor, a feature that continuously tracks CPU activity per thread on resource-limited devices. When a freeze, overload, or timing anomaly occurs, TaskMonitor automatically captures a trace for analysis in Tracealyzer®, giving developers actionable insight without manual intervention.
