i.MX6Q Linux BSP 4.1.0 for SABRE-SDP rootfs issue

Question asked by Dmitry Varakin on Sep 27, 2013

Hello!

 

I built Linux and rootfs with the latest i.MX6Q Linux BSP version 4.1.0 for SABRE-SDP. In order to save rootfs in tar.bz2 format and feed it to MFGTool I'm keeping temporarily directory rootfs.tmp and compressing it by the command:

  tar -jcvf ../rootfs.tar.bz2 *

 

Here's the a part of ll of compressed directory:

  drwxr-xr-x  2 user user 4096 Sep 27 14:15 bin/

  drwxr-xr-x  2 user user 4096 Sep 27 14:14 dev/

  drwxrwxrwx  7 user user 4096 Sep 27 14:15 etc/

  drwxr-xr-x  3 user user 4096 Sep 27 14:14 home/

  ...

  drwxr-xr-x  2 user user 4096 Sep 27 14:13 sys/

  drwxrwxrwt  3 user user 4096 Sep 27 14:14 tmp/

  drwxr-xr-x  2 user user 4096 Sep 27 14:15 unit_tests/

  ...

 

In other words, as good as usual.

Being flashed to SD card this image fails to boot because of some permission issues like the following:

  starting pid 1448, tty '': '/etc/rc.d/rcS'

  Mounting /proc and /sys

  mount: permission denied (are you root?)

  mount: permission denied (are you root?)

  /etc/rc.d/init.d/udev: line 11: /proc/sys/kernel/hotplug: No such file or directory

 

Full boot log is attached.

 

Pre-built rootfs image that comes with MFGtool is booting normally with the same uImage and u-boot. In both cases /etc/rc.d/rcS and surrounding files are equal including content and permissions. Inittab-s are completely equal as well.

 

Asking for advice. Does anybody have an idea?
