## 使用指南<a name="section17866411262"></a>

-   partition命令用来查看flash分区信息。
-   仅当使能yaffs文件系统时才可以查看nand flash分区信息，使能jffs或romfs文件系统时可以查看spinor flash分区信息。

## 使用实例<a name="section1927174202610"></a>

举例：partition spinor

## 输出说明<a name="section11321011223"></a>

查看spinor flash分区信息

```shell
OHOS # partition spinor
spinor partition num:0,  blkdev name:/dev/spinorblk0, mountpt:/, startaddr:0x00500000, length:0x00a00000
```
