5 NandFlash格式化失败

发布于 2022-08-18 17:50:05 浏览：659 订阅该版

使用的NandFlash是MKDV1GIL，1Gbit，能够注册成块设备，但是在dfs_mkfs格式化时，一直报失败“To initialize device:MKDV1GIL?failed. The error code is 2”，请问一下有没有遇到这种问题的啊，该怎么解决，flash也换过一个试了
相关代码：
```c
    rt_hw_spi_device_attach("spi2", "spi20", GPIOB, GPIO_PIN_12);  // CS 脚：PB12 
/*将MKDV1GIL抽象为系统使用的块设备*/
    if (msd_init("MKDV1GIL", "spi20") != RT_NULL)
    {
        rt_kprintf("sd init is err\n");
        return -RT_ERROR;
    }

spi2_dev= rt_device_find("MKDV1GIL");
    if (spi2_dev == RT_NULL)
    {
        return;
    }
    int result = 0;
    result = dfs_mount("MKDV1GIL", "/", "elm", 0, 0);
    if(result == RT_EOK)
    {
        rt_kprintf("okokok");
    }
    else
    {
        result = dfs_mkfs("elm", "MKDV1GIL");
        if(result == RT_EOK)
        {
            result = dfs_mount("MKDV1GIL", "/", "elm", 0, 0);
        }
        else
        {
            rt_kprintf("nonono");
            return;
        }
        rt_kprintf("okokok");
    }
```
控制台打印：
