Which FreeRTOS function is used to allocate memory safely?
AvPortFree()
Bmalloc()
CxTaskCreate()
DpvPortMalloc()
Step-by-Step Solution
Solution:

  1. Step 1: Identify allocation functions in FreeRTOS

    pvPortMalloc() is the FreeRTOS-safe function to allocate memory dynamically.

  2. Step 2: Differentiate from other functions

    vPortFree() frees memory, malloc() is standard C but not FreeRTOS-safe, xTaskCreate() creates tasks.

  3. Final Answer:

    pvPortMalloc() -> Option D

  4. Quick Check:

    Allocate memory = pvPortMalloc() [OK]
Quick Trick: Allocate memory with pvPortMalloc() in FreeRTOS [OK]
Common Mistakes:
  • Using malloc() instead of pvPortMalloc()
  • Confusing free and malloc functions
  • Choosing task creation function by mistake
