How do I creat a jffs2 image?

Thank you for your help. As far as the IDE goes, I'm perfectly happy to use the command line environment. Its just that I'm not familiar with cygwin, nios2 ide, or the nios2 command line tools.

If you can find your port, that would be great. It would at least provide me with validation for my own effort. In the meantime, I've copied the mtd code over to my cygwin environment and am trying to port it over also.

Does the porting mostly involve redirecting library and include directories, or is there custom coding involved?
