I am trying to run linux kernel (Linux version 2.4.4 downloaded from DENX) on MPC8XXFADS (CPU:860T) board. The root file system is mounted via NFS. The root file system I used is the one coming with DENX's ELDK package (I use ELDK cross compile tools). The problem is that once the linux kernel boots up I lose serial console(e.g. no loggin prompt). There is one warning message as the last printout on my console terminal: "Warning: unable to open an initial console". I look at the root file system on my host linux box and found out that there is no device file populated under "opt/eldk/ppc_8xx/dev". I wonder the root file system I used may not be a complete file system. Any ideas? Thanks for any hints.
RTFM.
The ELDK documentation (see file README.html) clearly states that you
have to run the two scripts ELDK_MAKEDEV and ELDK_FIXOWNER before you
can use the filesystem as NFS root.
Best regards,
Wolfgang Denk

If programming was easy, they wouldn't need something as complicated
as a human being to do it, now would they?
