You could unpack a very small ROM files system or something
into RAM.

You don't need FS for such application. Kernel should work without FS;
you just need some way of telling it where the program's CS begins in
memory-mapped ROM/flash.

embedded system without filesystem

[Pieter Grimmerink]

I just read something about your project ELKS,
and I was wondering whether I could use it for the
embedded system I'm writing software for.
(80188 processor, several external UARTs, 
16x2 LCD display)

We have written our own OS for this system. 
Since it does not have a harddrive or floppydrive,
but the applications are programmed in flash, 
we have to start the applications from a fixed address.

I thought I might get your kernel to work by changing some 
load addresses, and then writing it in flash on address 0x0
(or put a jump there to the actual kernel start address)

Should I give this a try, or would it be a waste of time,
because I can never mount a root filesystem?

Or does anyone know of other embedded linux projects,
that work without a filesystem?

Best regards,

Pieter
