Linux mtd driver interface 引言 MTD(memory technology device内存技术设备)是用于访问memory设备（RAM、ROM、flash）的Linux的子系统。MTD的主要目的是为了使新的memory设备的驱动更加简单，为此它在硬件和上层之间提供了一个抽象的接口。MTD的所有源代码在/drivers You signed in with another tab or window. Thomas Gleixner. Although character and block device files already existed, their MTD NAND Driver Programming Interface¶ Author:. [MTD Interface] MTD compatibility function for nand_do_read_ecc. struct mtd_info *mtd MTD device structure loff_t ofs offset byte address uint64_t len number of bytes to lock (must be a multiple of block/page size) int nand_unlock (struct mtd_info *mtd, loff_t ofs, uint64_t len) ¶ [MTD Interface] Unlock the NAND flash. struct mtd_info *mtd MTD Dec 2, 2012 · The Linux kernel implements a Memory Technology Device (MTD) subsystem that allows to access and control the various types of flash devices with a common interface. MTD drivers are not normally directly accessed by user code, but are usually bound to another, higher level device driver. The MTD subsystem was created to provide an abstraction layer between the hardware-specific device drivers and higher-level applications. Jul 14, 2020 · MTD(Memory Technology Device)即常说的Flash等使用存储芯片的存储设备，MTD子系统对应的是块设备驱动框架中的设备驱动层，可以说，MTD就是针对Flash设备设计的标准化硬件驱动框架。 MTD NAND Driver Programming Interface¶ Author:. Also, this driver allows reading and writing to the whole NAND flash from Linux, including the boot0 bootloader which is loaded by eGON.
