在main.c里面的while外面执行测试程序

void Simple_NAND_Test(void)
{
        memset(write_buf, 0x55, sizeof(write_buf));

        NAND_IDTypeDef nand_id={0};
        NAND_AddressTypeDef nand_addr;
        nand_addr.Block = 0;
        nand_addr.Page = 0;
        nand_addr.Plane = 0;
//
        HAL_NAND_Reset(&hnand1);

//
        HAL_NAND_Read_ID(&hnand1,&nand_id);
//  
        HAL_NAND_Erase_Block(&hnand1,&nand_addr);
//
        while(HAL_NAND_GetState(&hnand1) != HAL_NAND_STATE_READY);
//
        HAL_NAND_Write_Page_8b(&hnand1,&nand_addr,write_buf,1);

//      HAL_NAND_Read_Status(&hnand1);
        //NAND_WritePage(20,0,read_test);
//  
//      memset(write_buf, 0, sizeof(write_buf));
//
        HAL_NAND_Read_Page_8b(&hnand1,&nand_addr,read_test,1);
//      NAND_Read_Page_With_ECC(20,5,read_test);

}

执行出的结果全为0XFF
