I asked this before, but I've already upgraded the kernel to the 2008R1.
I am using a nfs to the rootfs, maybe that's the reason I can't connect.
I also want to disable the console.
Any idea?
Thanks.

Message: 55253 if you're using a nfs root, then you need to create all the device nodes by hand, or make sure mdev is enabled in your /etc/rc file
refer to the rc file that comes with the ADI boards

Message: 55279 Hi, I am trying to build a jffs2 root.
I made the changes in the kernel configuration, but when I do "make", it doesn't build the "uImage", why is it?.
These are the files that are build:

I get this:

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

what should I modify?, bootargs? or it is a kernel configuration problem?.

you didnt enable any flash drivers, thus no mtd mappings were created, thus the root filesystem couldnt be found as "mtdblock2" doesnt represent any device
if you want root devices to be available during booting, you need to build the relevant drivers into the kernel
please consult the documentation:

Hi,
I just wanted to add my solution to this. It goes along with what Mike said about enabling mdev. However, this is the section in my /etc/rc that was supposed to enable mdev:
if [ -e /bin/mdev ] && [ -e /proc/sys/kernel/hotplug ] ; then
mount -t tmpfs mdev /dev -o exec,nosuid,mode=0755,size=10M
echo /bin/mdev > /proc/sys/kernel/hotplug
/bin/mdev -s
fi
I checked on the system and /bin/mdev was there, but no /proc/sys/kernel/hotplug. So I used make xconfig to set CONFIG_HOTPLUG=y
General setup -> Configure standard kernel features (for small systems) -> Support for hot-pluggable devices
After a fresh make, I was able to telnet in with no problem.
-Ben

Just an update for people... this problem is still there and is still a bit of a pain in the ***, even with 2009R1.1-RC4.
I turned on mdev, enabled CONFIG_HOTPLUG and used the non-busybox telnetd. I did NOT enable "do not use openpty" (i.e. it is using openpty).
When this did not work, I went back to the kernel config and turned CONFIG_LEGACY_PTYS ("Legacy (BSD) PTY support"). I already had Unix98 PTY support enabled.
With both of these enabled, mdev and hotplugging enabled, the non-busybox telnetd and using openpty for telnetd, it works. What a pain in the ***.
BTW: busybox's telnetd causes a NULL pointer exception as soon as a connection attempt is made.
