I’m using FreeRTOS with CMSIS v1 on STM32F469 uC. Inside project there’s used heap_4.c
I’d like to know how vPortFree really works.
uint8_t* ptr; //declaration of pointer ptr = (uint8_t*)pvPortMalloc(sizeof(uint8_t)); //assing address on heap - 0x20007e58 if(ptr == NULL) return -1; //if my pointer is not assigned return from function *ptr = 0xFF; //assign value to reserved address vPortFree((void*)ptr); //free memory, so ptr should be NULL, but it's still 0x20007e58
Am I right with understanding vPortFree? Should it assing NULL to the ptr?
