FreeRTOS - RTOS Fundamentals

Identify the error in this FreeRTOS code snippet for a hard real-time task:

void vTaskFunction(void *pvParameters) {
  while(1) {
    // Critical processing
    vTaskDelay(1000);
  }
}

What is the problem?

AvTaskDelay should be replaced with vTaskDelete.

BThe task function lacks a return statement.

CThe infinite loop will crash FreeRTOS.

DUsing vTaskDelay causes deadline misses in hard real-time tasks.

Step-by-Step Solution

Solution:

Step 1: Analyze vTaskDelay in hard real-time context
vTaskDelay pauses the task, which can cause missing strict deadlines in hard real-time.
Step 2: Check other options for correctness
Return statement is not needed in infinite loop, infinite loops are normal, vTaskDelete deletes task, not delay.
Final Answer:
Using vTaskDelay causes deadline misses in hard real-time tasks. -> Option D
Quick Check:
Hard real-time tasks avoid vTaskDelay [OK]

Quick Trick: Hard real-time tasks avoid delays that cause misses [OK]
