RE: File system problem

Hi,
Thank you very much for your answers.

But I have both console and null in /dev.

-rw-rw-rw- 1 mojtaba mojtaba    0 2007-12-26 15:50 console
-rw-rw-rw- 1 mojtaba mojtaba    0 2007-12-26 15:50 null

They have been created by buildroot. Do I need to create them manually?
Actually the size of both of them is 0 and both are empty files. Is that =
a
problem?

Thank you in advance and best regards,
Mojtaba

I am trying to boot a root file system build by buildroot. But I got =

this

error" init has generated signal 11 but has no handler for it".

My kernel version is 2.6.24-rc3
My target system is PPC 405 (XILINX VIRTEX II pro) I am using the

snapshot of buildroot.

Hi Mojtaba,

I got a similar error on my ML-310 when I tried a new root filesystem.
 As far as I recall, I needed to make sure that two entries existed in
/dev, namely:

crw-------    1 root     root       5,   1 Jan  1 05:18 console
crw-rw----    1 root     root       1,   3 Dec 10  2007 null

I think that you are missing /dev/console and then init cannot run
since it has nowhere to put its standard output.

You can make those by mounting your CF card on your development host
and (as root) make the nodes:

# mknod -m 660 /dev/console c 5 1
# mknod -m 660 /dev/null c 1 3

In my case, I use the UartLite (ttyUL0) serial port driver, but I'm
pretty sure this is going to fix the problem you are observing.
