medium📝 Predict Output Q4 of 15

FreeRTOS - Debugging and Monitoring

ATask A runs continuously without preemption

BTask B waits unusually long despite higher priority

CAll tasks run equally with no delays

DSystem crashes immediately after start

Step-by-Step Solution

Solution:

Step 1: Understand priority inversion symptom
Priority inversion causes a higher priority task to wait longer than expected because a lower priority task holds a resource.
Step 2: Match symptom to runtime monitoring output
Runtime monitoring shows Task B (higher priority) waiting unusually long, indicating priority inversion.
Final Answer:
Task B waits unusually long despite higher priority -> Option B
Quick Check:
Priority inversion detected by long wait = Task B waits unusually long despite higher priority [OK]

Quick Trick: Long wait of high priority task signals priority inversion [OK]
