我在这里测试NAND FLASH，程序是

HAL_StatusTypeDef Simple_NAND_Test(void)
{
    HAL_StatusTypeDef status;
    NAND_AddressTypeDef addr = {0};  // 块0，页0


    for (uint32_t i = 0; i < 20; i++) 
        {
        write_buf[i] = i & 0xFF;
    }

    status = HAL_NAND_Erase_Block(&hnand1, &addr);
    if (status != HAL_OK) 
        {
        return HAL_ERROR;  // 擦除失败
    }

    // 4. 写入页0
    status = HAL_NAND_Write_Page_8b(&hnand1, &addr, write_buf, 1);
    if (status != HAL_OK) 
        {
        return HAL_ERROR;  // 写入失败
    }
        memset(write_buf, 0, 20);

    // 5. 读取页0
    status = HAL_NAND_Read_Page_8b(&hnand1, &addr, write_buf, 1);
    if (status != HAL_OK) 
        {
        return HAL_ERROR;  // 读取失败
    }


    return HAL_OK;  // 测试通过
}

这里在HAL_NAND_Erase_Block卡死

和NAND通讯失败

和NAND通讯失败

FMC的引脚需要拉高或者拉低吗？使用CubeMX默认配置的，无上拉和下拉
