然后在用ubiblock --create /dev/ubi3_0去创建/dev/ubiblock3_0 一直报下面错误: ubiblock: error!: UBI block is not present in the system ubiblock: error!: cannot create block device error 38 (Function not implemented) 内核配置defconfig中也将CONFIG_MTD_UBI_BLOCK相关的打开了,但是一直报错,有...

如下所示,/dev/mtd0至/dev/mtd10对应uboot分区,mtd21对应固件分区,mtd20就是本文将要用到的数据分区。 root:/dev# ls mtd* |grep -v block mtd0 mtd16ro mtd23ro mtd30ro mtd0ro mtd17 mtd24 mtd31 mtd1 mtd17ro mtd24ro mtd31ro mtd10 mtd18 mtd25 mtd3ro mtd10ro mtd18ro mtd25ro mtd4...

On DHCOM Systems with Linux the UBIFS Filesystem is used for the NAND-Flash root-filesystem. The Unsorted Block Image File System (UBIFS) is a filesystem for use with raw flash memory media. UBIFS works on top of an Unsorted Block Images (UBI) device, which is itself on top of an ...
ubi是Unsorted Block Image的简称,ubifs是Unsorted Block Image File System(无序区块镜像文件系统)的简称,构建于MTD之上,可操控大容量的Nand flash. nand flash, mtd 和ubifs三者关系可以简述为:nand flash作为硬件设备,mtd介于硬件设备和用户层间提供抽象接口,ubifs是在mtd之上构建的文件系统,方便对nand flash进行数据...
