S32K144内存分配

本文将通过实际的工程代码介绍NXP S32K144单片机变量地址分配，应用笔记仅用于自己学习及大家参考。

示例代码如下：

uint8_t num_byte[4];
uint32_t num_word;
const uint32_t num_word_const = 0x1234;
uint32_t *point_heap;
int main(void)
{
uint8_t num_byte_stack;
static uint8_t num_byte_static;

point_heap = (uint32_t *)malloc(4);
*point_heap = 0x3421;
free(point_heap);

num_byte_stack = 0x11;

printf("num_byte addr is 0x%x\r\n",&num_byte);
printf("num_word addr is 0x%x\r\n",&num_word);
printf("num_word_const addr is 0x%x\r\n",&num_word_const);
printf("point_heap addr is 0x%x\r\n",&point_heap);
printf("point_heap is 0x%x\r\n",point_heap);
printf("num_byte_stack addr is 0x%x\r\n",&num_byte_stack);
printf("num_byte_static addr is 0x%x\r\n",&num_byte_static);
}
