uclinux problem with romfs

I followed the description at
http://www.uclinux.org/pub/uClinux/utilities/armulator/ to get into
uclinux. However, the "Loaded ROM boot.rom" message from the example
session is missing in my gdb output, and the system seems to be stuck
in a loop (see below).

Can anyone help me to successfully load the ROM image?

If I load kernel linux.2.4.x, gdb says "Program exited normally."
without doing anything else. (details see below the linux.2.0.x
output.)

Regards,
Herbert
