Subject: Timeout error with NFS over USB
Date: Fri, 17 Jan 2003 10:10:45 +0530 [thread overview]
Message-ID: <3E27894D.1080F3D@ncoretech.com> (raw)
Hi,
I am working on an embedded board running on a StrongARM SA1110
processor.
It has got Linux (kernel 2.4.18 - rmk4) running on it. I am trying to
mount a
partition from the native linux machine (running on RedHat 7.3) through
NFS
over USB.
I have set up the native linux system as the NFS Server (I have made the
appropriate entries in the /etc/exports and /etc/hosts.allow and
/etc/hosts.deny
files). I then mount the folder that has been exported by the NFS
Server.
Everything seems to work fine upto here. I have got a couple of issues:
1. When I telnet into the target board, I am able to log in without any
issues
and work on the mounted partition. But, every now and then, I get
the
following message on the target board:
NETDEV WATCHDOG: usbf: transmit timed out
On the target board, the binary utilities (like ls, cp, mv, mount) are
all part of
busybox (version 0.60.5).
On the native Linux system (NFS Server)

/etc/exports reads:
/skiff 1.1.1.1(rw)
/home/winnie 1.1.1.1(rw)

ip address of the native host)

I am not running the portmap daemon on the target board. I have only
set up the NFS Server,
turned on NFS capability in the Linux Kernel for the target board and I
mount the partition
exported by the NFS Server, using the mount command from busybox.
Has anyone faced this timeout errors before? If it has been, is there a
fix?
Thanks in advance,
Kanagesh
