[Solved] Given the code snippet:void vTask(void *pvParameters) { int ... while(1) { /* task code */ } }xTaskCreate(vTask, "Task", 50, NULL, 1, NULL);What is the likely problem with this stack size allocation? | FreeRTOS

FreeRTOS - Task Creation and Management

Given the code snippet:

void vTask(void *pvParameters) { int a[50]; while(1) { /* task code */ } }
xTaskCreate(vTask, "Task", 50, NULL, 1, NULL);
What is the likely problem with this stack size allocation?

AStack size is too small to hold the local array 'a'

BStack size is too large and wastes memory

CStack size matches the array size perfectly

DStack size should be specified in bytes, not words

Step-by-Step Solution

Solution:

Step 1: Analyze local variable size
The array 'a' has 50 integers; each integer is typically one word, so it needs 50 words minimum.
Step 2: Consider additional stack usage
Besides 'a', the task needs stack for function calls and other variables, so 50 words is too small.
Final Answer:
Stack size is too small to hold the local array 'a' -> Option A
Quick Check:
Stack size must cover all local data plus overhead [OK]

Quick Trick: Stack size must cover all local variables plus overhead [OK]

Common Mistakes:

Assuming stack size equals local array size is enough
Ignoring extra stack needed for function calls
Confusing words with bytes
