Answer 1

As pointed in comment, see Heap Memory Management, freertos doesn't provide malloc/free functions.

You'll have to:

• Modify FreeRTOSConfig.h to set
  • configSUPPORT_DYNAMIC_ALLOCATION to 1
  • configAPPLICATION_ALLOCATED_HEAP to 4 (you can replace 4 according to your needs)
• Add the file heap_4.c to your project (same remark as above)
