FreeRTOS Kernel Debug

Overview

Use this skill to debug FreeRTOS by proving tick, scheduler state, task stacks, heap, ISR boundaries, and synchronization ownership. Many FreeRTOS failures are contract violations around interrupt priority or blocking context.

When To Use

Use this skill when:

• The user is debugging FreeRTOS tasks, queues, semaphores, mutexes, timers, event groups, streams, or task notifications.
• The issue involves hard faults, hangs, missed ticks, watchdog resets, stack overflow, heap exhaustion, priority inversion, or ISR API misuse.
• The target uses vendor HAL callbacks, Cortex-M interrupt priorities, trace tools, or multiple heap implementations.
