I'm also using Linux 2.4.25 using the ELDK and I would recommend
getting a NFS root file system going first discussed in the following
paper, although written for a MPC5200 is an excellent guideline:
http://emsys.denayer.wenk.be/emcam/Linux_on_MPC5200_(UK).pdf
Worry about a compressed system later. There is also a script for
building a
small root file system (mkrootfsdenx) from a working reference one and
MTD is the way to go to manage your flash for F/W updates and NVdata store.
happy ELDKing,
Frank Bennett
