You are trying to mount a root filesystem over nfs (ie not NOR)
For NOR work with the 2.6.10 kernel I would suggest a ext2 initrd
minimal Busybox image with jffs2 partitions mounted after the initial
boot and dev setup. With the jffs2 partitions you can then move forward
and introduce unionfs for persisting configuration changes over reboots.
The minimum amount of devices required on a basic busybox install are;
mknod $(BUILD_DIR)/$(OUTPUT_DIR)/dev/console c 5 1;
mknod $(BUILD_DIR)/$(OUTPUT_DIR)/dev/tty1 c 4 1;
mknod $(BUILD_DIR)/$(OUTPUT_DIR)/dev/tty2 c 4 2;
mknod $(BUILD_DIR)/$(OUTPUT_DIR)/dev/tty3 c 4 3;
mknod $(BUILD_DIR)/$(OUTPUT_DIR)/dev/tty4 c 4 4;
mknod $(BUILD_DIR)/$(OUTPUT_DIR)/dev/tty5 c 4 5;
You may also need to include some libs unless you have statically
compiled them in;
lib/
lib/ld-2.3.3.so
lib/ld-linux.so.3
lib/libm-2.3.3.so
lib/libc.so.6
lib/libm.so.6
lib/libc-2.3.3.so
