MTD Character Devices-usually referred to as/dev/mtd0,/DEV/MTD1, and so on. These character devices provide I/O access to the raw flash. They support a number of IOCTL calls forErasing Eraseblocks, marking them as bad or checkingifAn eraseblock are bad, getting information about MTD devices, etc. The SYSFS interface is relatively newer and it provides full information on each MTD deviceinchThe system. This interface is easily extensible and developers be encouraged to use the Sysfs interface instead of older IOCTL OR/PR OC/MTD interfaces, when possible. The Sysfs interface forThe MTD subsystem is documentatedinchThe kernel, and currently can be found at documentation/abi/testing/sysfs-class-MTD. the/PROC/MTD procfileSystemfileProvides general MTD information. This is a legacy interface and the Sysfs interface provides MoreInformation.
