If your problem is with the filesystem, then this has nothing to do
with your flash (which hosts uboot, the kernel and busybox). You will
need to reformat your USB stick and put a fresh copy of the "roach"
file on there. This will erase all your customised settings though. I
suspect you've managed to corrupt your filesystem and it's now
mounting RO or something.
I am concerned about your statement of the OS crashing. Why did it
crash? Linux is pretty stable and doesn't usually crash easily. Is
this a problem with the ROACH, or was it due to a user-action?
FWIW, if you want to update your flash, see the step-by-step guide
here: http://casper.berkeley.edu/wiki/ROACH_kernel_uboot_update
Note that we are working on a new uBoot image as I write this email
and there will be an update released later today or on monday. The
primary change is to optimise the clock speeds around the PPC.

Hi Jason:
Thanks for your great help. But even auot eth0 is added, the network
still could not come up automatically.
And my USB file system is FAT32 R/W. I am not sure what the file
system is for the on board flash.
I agree with you that this should be a filesystem problem.
I think this problem is popped up only when the OS is crashed for a
few times. But this problem could not be fixed even I update the
Uboot and the image on the Roach board. Is there anyway I can erase
all the on board flash and reprogram them again?
Thanks

Subject: Re: [casper] Roach issue: Stale NFS file handle error is
reported
This is complaining about the statefile (ifstate) not being writeable.
This is probably a problem with your filesystem. Are you using an NFS
filesystem? is it mounted R/W, or Read-only?
BTW, now that I've seen your interfaces file, I suspect the reason
your interface is not coming up automatically is because you've left
out the "auto eth0" line...
auto eth0
iface eth0 inet static
address 192.168.1.36
netmask 255.255.255.0
gateway 192.168.1.1

Hi:
In order to set a static IP address to roach Ethernet port, I insert
the following configuration to the /etc/network/interfaces:
iface eth0 inet static
address 130.155.199.211
netmask 255.255.240.0
gateway 130.155.192.2
dns-nameservers 130.155.194.32 130.155.192.40
Then I
ifdown eth0
ifup eth0
So the Ethernet port works properly.
But when I restart the Roach, I could not run ifdown and ifup
command anymore. A failure is reported:
ifdown: failed to open statefile /etc/network/run/ifstate: Stale NFS
file handl
Then I run ls /etc/network/run/ifstate, similar error is reported:
ls: /etc/network/run/ifstate: Stale NFS file handle
This is repeatable.
Anybody has any idea?
Thanks
Wan
