mtd设备的分层-Linux MTD Introduction: MTD (memory technology device memory technology and equipment) is used to access memory devices (ROM, flash) subsystem of Linux. The main purpose of MTD in order to make the new memory device driver more simple, for it among the top in the hardware and provides an abstract interface. MTD All source code in/drivers/mtd subdirectory. I will CFI interface is divided into four MTD devices (from device node until the underlying hardware drivers), this four-story from top to bottom are: device node, MTD device layer, MTD layer original equipment and hardware driver layer. Root file system file system character device node MTD character device MTD block device MTD Original Equipment hardware drivers FLASH block focused on the definition of MTD, as well as equipment mtdmtd Why should there be a stratified
