mtdblock提供了一个在MTD设备上操作文件系统的途径,为用户提供了更便捷和高效的方式来管理存储设备。 JFFS2是一个在Linux内核中常用的文件系统类型,特别适用于Flash存储设备。JFFS2(Journaling Flash File System 2)是一种日志式的文件系统,它能够提供快速的读写操作,并对数据进行有效地管理和保护,避免了传统文件系统...
However, there is an unusual way to make UBIFS work with a file-backed image using NAND simulator (seehere). If your image is not very big, then you can create a RAM-backednandsimMTD device, then copy your image to that emulated MTD device. If the image is large and you do not ha...

This procedure is the reason there are specific file systems for MTD devices, like JFFS2 and YAFFFS, and flash translation layers (FTL) like NFTL, INFTL, etc. These FTLs and file systems take special care of MTD device properties to hide complexity from the user. ...
