u8 *BlackImage, *RedImage;
    u16 Imagesize = 0x7800;
    if((BlackImage = (u8*)malloc(Imagesize / 2)) == NULL) {
        printf("Failed to apply for black memory... ");
        return -1;
    }
    if((RedImage = (u8*)malloc(Imagesize / 2)) == NULL){
        printf("Failed to apply for red memory... ");
        return -1;
    }
为什么程序里加了这段代码 单步调试时会进入
void HardFault_Handler(void)
{
  /* Go to infinite loop when Hard Fault exception occurs */
  while (1)
  {}
}
出现这样的错误

？
