What /dev management solution are you using? Static? Dynamic?

If you're using one of the dynamic solutions (devtmpfs, mdev or udev),
make sure that your kernel is built with CONFIG_DEVTMPFS and
CONFIG_DEVTMPFS_MOUNT. When the kernel is built by Buildroot, Buildroot
automatically enables those options. When your kernel is built
manually, you have to make sure those options are enabled.

Best regards,

Thomas
