Hi Jason: Thanks for you great help. I reformat my USB stick and copy a fresh Roach core into it. Then I insert the following configuration into /etc/network/interfaces with VI.
auto eth0 iface eth0 inet static address 130.155.199.211 netmask 255.255.240.0 gateway 130.155.192.2 Then I reboot the Roach again. The network could not be up automatically as normal. And I still receive ls: /etc/network/run/ifstate: Stale NFS file handle When I run ls /etc/network/run/ifstate The customised setting could be erased after I use a fresh core. But this problem still there and repeatable. And I don't think the file system is in RO because I can see my configuration in interfaces file after rebooting roach. I could not remember why the OS is crash. I will write it down when it crashes again. I think it was crashed when I use Apt-get install and apt-get -f install. I received no available disk space error. I guess something in the Roach board flash are also affected. But they could not be resumed by reprogramming the Uboot and OS Image. Any idea?

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. Jason On 22 May 2009, at 08:01, <wan.ch...@csiro.au> wrote: > Hi Jason: > > Thanks for your great help.
