[microblaze-uclinux] writeble filesystem - whitout flash

["A. Arthur Mohr" <adimbox-uclinux@xxxxxxxxxxxx>]

    Hello again !
    
    Thanks to everybody, looks like SSH will work this time :)
    
    The thing is SSH needs to create files, groups and users and I need to  edit SSH's config file. As I don't want to compile a new kernel every  time I change that file, I need to write it on the fly.
    
    As I looked in the archives, the way to go is JFFS2. BUT, that is for Flash.
    Unfortunetly, I have no flash, so I can't use it. Using only romfs is  no good, 'cause you know it mounts a read-only fs. I tryed to use only  EXT3 and 'second extended fs support - ext2_fs, but the kernel panics.
    
    Well then ... what should I use to get a writeble fs, having only RAM  to execute ? I dont care if I loose everything when I shut down the  board, by now ...
