FreeRTOS - Debugging and Monitoring

Examine this code snippet:

int *ptr = NULL;
configASSERT(ptr = NULL);

What is the main issue causing unexpected behavior?

AThe assertion uses assignment '=' instead of comparison '==', causing the condition to always be false.

BThe pointer is initialized incorrectly; it should not be NULL.

CconfigASSERT() cannot be used with pointers.

DThe assertion condition is correct; no issue exists.

Step-by-Step Solution

Solution:

Step 1: Identify the operator used
The code uses ptr = NULL inside configASSERT(), which is an assignment, not a comparison.
Step 2: Effect of assignment in assertion
Assignment returns the assigned value (NULL), which evaluates to false, causing the assertion to fail every time.
Final Answer:
The assertion uses assignment '=' instead of comparison '==', causing the condition to always be false. -> Option A
Quick Check:
Assignment used instead of comparison [OK]

Quick Trick: Use '==' for comparison, not '=' [OK]
