Solution:Step 1: Analyze the pointer value and assertionptr is NULL, but configASSERT checks ptr != NULL, which is false.Step 2: Understand configASSERT() behavior on false conditionWhen the condition is false, configASSERT() halts the program immediately, causing the crash.Final Answer:The pointer

[Solved] You wrote this code:int *ptr = NULL;configASSERT(ptr != NULL);But the program crashes immediately. What is the most likely cause? | FreeRTOS

FreeRTOS - Debugging and Monitoring

You wrote this code:

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

But the program crashes immediately. What is the most likely cause?

AThe pointer should be NULL to avoid crash

BThe pointer ptr is NULL, so configASSERT() halts the program

CconfigASSERT() syntax is incorrect and causes crash

DconfigASSERT() only works in release builds

Step-by-Step Solution

Solution:

Step 1: Analyze the pointer value and assertion
ptr is NULL, but configASSERT checks ptr != NULL, which is false.
Step 2: Understand configASSERT() behavior on false condition
When the condition is false, configASSERT() halts the program immediately, causing the crash.
Final Answer:
The pointer ptr is NULL, so configASSERT() halts the program -> Option B
Quick Check:
NULL pointer fails assert halting program = C [OK]

Quick Trick: Crash means assert condition was false, check pointer value [OK]

Common Mistakes:

Thinking configASSERT() syntax caused crash
Believing NULL pointer is safe here
Assuming configASSERT() runs only in release
