FreeRTOS - Memory Management
Given FreeRTOS configured with heap_2, what happens if you allocate memory and then free it before allocating again?
AFreeRTOS ignores the free call silently
BMemory is never freed, causing a leak
CProgram crashes due to invalid free
DMemory is freed and can be reused for new allocations
Step-by-Step Solution
Solution:

  1. Step 1: Understand heap_2 behavior

    heap_2 supports freeing memory, so freed blocks can be reused for future allocations.

  2. Step 2: Analyze the effect of free before new allocation

    Since memory is freed properly, the next allocation can reuse that space without issues.

  3. Final Answer:

    Memory is freed and reused for new allocations -> Option D

  4. Quick Check:

    heap_2 supports free and reuse = Memory is freed and can be reused for new allocations [OK]
Quick Trick: heap_2 allows free and reuse of memory blocks [OK]
Common Mistakes:
  • Assuming heap_2 leaks memory
  • Thinking free causes crash
  • Believing free is ignored
