[Buildroot] Still "Can't open /dev/tty1[2,3]", Please HELP

[Steven Woody]

After guess and guess and build and burn,  my rootfs still can not
boot, it always get "Can't open /dev/tty1[2,3...]" after kernel loaded
just load it.  I attached the full boot message and my buildroot
.config, I hope, with best regards, someone could help me.

Thanks in advance.

I couldn't work out where your target_skeleton and device table are
coming from based on your config. Do you have a device table, and does
it have those /dev/tty1,2,3,4 devices?

Maybe you could post the output of the build process.

Your inittab is obviously trying to make directories in a read-only file
system which isn't going to work. Not that it's related.

The problem had gone away after I add udev to the packages.  I am not
sure whether the absence of udev is really the reason that cause the
previous "can't open /dev/tty?" problems.

But I still like to know what you mentioned 'device table'. I want to
ask, what is and where is the 'device table'?  I dont find the
concepts in buildroot on-line doucments.  Thanks.

Yes, you are right. I did not notice it at first time.  But it was corrected.

You may see in my another post, I now can get the login prompt, and my
problem switchs to "Why I can not login". I hope I can get your help
in that thread.

Have a look at target/generic/device_table.txt and
target/generic/mini_device_table.txt.
You define by the buildroot config which file is used to generate the
targets device table.

sorry for the stupid ... I append the exact file with the folllowing line
  /usr/local              d       755     0       0       -       -
   -       -       -
to ensure the target/generic/device_table.txt really works.  But after
full build, I don't find /usr/local under the root. So,,,  what
'device_table.txt' should I go to use?

Where is the definition for the target device table file name?  Thanks.

sorry, Emil, for this problem,  I found what mattered is
target/generaic/mini_device_table.txt instead of
target/generic/device_table.txt.   Please focus on my another thread
and be kindly to help me resolve the "can not login" or "getty exited"
problem.  Thanks.
