[Buildroot] /dev files not being created correctly

[Buildroot] /dev files not being created correctly

[Mark Fisher]

Hi,

I'm relatively new to buildroot and am using the 2009.02 release of buildroot on a Fedora 9 platform and targeting an embedded device with an Intel Atom processor. 

When the root filesystem is built the types of the files are all set to plain text files. So for instance the /dev/console is not set to be a character device. This has already create problems when I try to boot because the console could not be opened. I manually fixed /dev/console and /dev/null. I'm still having trouble booting the image and also after a?re-build my custom changes were lost.

Is this a known problem, and is there a fix? If not should I delete all the files in the /dev directory and then re-create them based on the settings in the device_table.txt?

Thanks,

Mark

The plain text files in /dev are just as they should be, but the rootfs with
those files is not the rootfs you want for your target. Try selecting a
different root file system type in menuconfig, like tar or ext2 or
something. By doing that you should get proper /dev/* files in your
generated rootfs images under ./binaries/<project>/.

You shouldn't use the project_build_arm/*/root directory to boot from
NFS. The /dev entries are normal files as we don't want to require
root rights while building. Instead create a tarball (target
filesystem options->tar the root filesystem) and extract that (found
under binaries/) as root on your nfs server.
