[Solved] Identify the error in this FreeRTOS task creation code:void vTaskCode(void *pvParameters) { while(1) { // Task code } } int main() { xTaskCreate(vTaskCode, "Task", 1000, NULL, 1, NULL);... | FreeRTOS

FreeRTOS - Task Creation and Management

Identify the error in this FreeRTOS task creation code:

void vTaskCode(void *pvParameters) {
  while(1) {
    // Task code
  }
}

int main() {
  xTaskCreate(vTaskCode, "Task", 1000, NULL, 1, NULL);
  vTaskStartScheduler();
  return 0;
}

ATask handle parameter is NULL, so task cannot be managed later.

BThe task function should not have an infinite loop.

CStack size is too large and causes memory overflow.

DvTaskStartScheduler() is called before creating the task.

Step-by-Step Solution

Solution:

Step 1: Check task creation parameters
The last parameter is the task handle pointer; passing NULL means the task handle is not stored.
Step 2: Understand implications of NULL task handle
Without a task handle, the program cannot control or delete the task later, which is usually needed.
Final Answer:
Task handle parameter is NULL, so task cannot be managed later. -> Option A
Quick Check:
Task handle NULL means no task control [OK]

Quick Trick: Always provide a task handle pointer to manage tasks [OK]

Common Mistakes:

Thinking infinite loops are wrong in tasks
Believing stack size is always too large
Assuming scheduler starts before task creation
