STM32读写25Q64遇到的BUG

25Q64写函数如下：

void Flash_Read_Array(unsigned long nAddr, unsigned char *pData, unsigned short nCount)
{
		unsigned char *pAddr;
		pAddr = (unsigned char *)&nAddr;
		
//		printf(".......................2\r\n");
		FLASHCSLow();
		
		Flash_Send_Byte(FLASH_CMD_READ);
		Flash_Send_Byte(*(pAddr + 2));
		Flash_Send_Byte(*(pAddr + 1));
		Flash_Send_Byte(*(pAddr + 0));
		while(nCount--)
		{
			*pData++ = Flash_Get_Byte();
		}
//		printf(".......................3\r\n");
		FLASHCSHigh();
}

如果按以下操作，会卡住：

sInnerRecord *tespRecord;
	Flash_Read_Array(INNER_FLASH_RECORD_START + index * sizeof(sInnerRecord), (uint8_t *)tespRecord, sizeof(sInnerRecord));

以下操作则可正常写入：

	sInnerRecord tespRecord;
	Flash_Read_Array(INNER_FLASH_RECORD_START + index * sizeof(sInnerRecord), (uint8_t *)&tespRecord, sizeof(sInnerRecord));
