Cygwin can't do that; the package just doesn't exist. You'll need to look inside the script and port it to work on Cygwin. If that's even possible; if it's trying to do work with file systems you might just not be able to use it at all. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Shortcoming is mainly in the time that file system is full or approach completely, because of the relation of refuse collection, the travelling speed of jffs2 is slowed down greatly; Cramfs compressibility is high, speed is fast, but its read only attribute is again a large defect, and user cannot be expanded its content.

If above two kinds of files are combined and can realize the advantage that had both met high compression, high-speed cruising, can meet again read-write advantage. Technical assignment of the present invention is to solve the deficiencies in the prior art, and the method for programming flash based on cramfs and jffs2 a kind of is provided.

Technical scheme of the present invention realizes in the following manner, the method of this kind of programming flash based on cramfs and jffs2, its specific implementation process is: the file system of first making cramfs form, and then making jffs2 formatted file, respectively by these two kinds of image file programmings in the different subregions of flash, set start-up parameter and increase by this partitioned file of step carry in the file system booting script of previously making, can realize on the rear automatic carry of system of start the file of different-format.

The detailed process of described programming method is:. Revise booting script, the image file of the jffs2 form of carry is added in starting up's script, after system boot, get final product like this data of carry jffs2 in the catalogue of cramfs file system;. Make cramfs root file system: the image file that by mkfs. New folder in linux main frame, and the module that will use or executable program directly copy in this file, is made into jffs2 form image file by mkfs.

Modification kernel code resets flash partition table and is used for depositing root file system and jffs2 formatted data image file;. In bootloader by programming order by file system with the programming of jffs2 packet in the different subregions of flash;.

In bootloader, set the root file system that starts the cramfs form that path is programming, start powers on and can enter into cramfs root file system, also can realize the image file of jffs2 form is mounted in local folders, the catalogue on hanging over is carried out to load-on module or read-write operation simultaneously. The beneficial effect that the present invention compared with prior art produced is:.

We use the mkfs. Now we have a container for the file system—the image file—which is standing in for a hard drive in this scenario. Now we need to mount the file system so that we can use it. We need to change the file ownership of the mount point so that we have read and write access to it. And now we should be able to use our new file system.

The files have been copied, so our file system has been created, mounted and used. Or so we think. In our home directory, we can create a new file system inside our existing image file. Be careful! If there are any important files on the file system inside the image file, mount the image file, and retrieve them before you create a new file system.

We can mount our image file with exactly the same command as before:. With Linux, as with most things, you learn by doing. The problem with some commands is that they are potentially destructive. The dilemma is how to practice using them without putting your system or data at risk?

You now have a simple method of creating and trying out file systems with mkfs that leaves your computer untouched. Use Google Fonts in Word. Customize the Taskbar in Windows What Is svchost. Best Home Theater Systems.
