I did try UML + blkmtd and jffs statically compiled in a couple of years ago and it then almost worked out of the box. It failed then for me due to a very small issue: the initializers in the different drivers initialized in the wrong order, so I got a panic due to a null-dereference. (driver initialization does/didn't have depencies).
Just me five cents :-) Stian On Tue, 2007-12-18 at 12:45 -0600, Rob Landley wrote: > I want to loopback mount a jffs2 filesystem, and this filesystem has > incestuous knowledge of flash devices for wear levelling and stuff, so it > will only mount an actual flash device and not a normal block device. > > There's a way to make a loopback device look like a flash device, letting you > loopback mount jffs2, but it involves recompiling the kerenel to add support > for it, and of course I went "User Mode Linux"...
