
Keep the board connecting with USB to the PC, and enable the ‘USB debugging’ from “Setting->About tablet”
options and then press 7 times for “Build number” and see the pop-up message on the display like “you are
now developer” then come out and then select the “Developer options->USB debugging” option

Now the board is configured as a adb device and do the below steps in Host PC to connect
$ adb kill-server
$ adb start-server
$ adb devices
(list the connected devices)
$ adb shell (board’s console will detect in host PC)
15. Why “avc: denied” print is appeared on console?
This information will be appeared on console which because of SElinux permission is ‘permissive’. This is just
an information and this will not affect any functionalities.
16. Why “Unsupported SD card” message is appeared on display?
By default the auto mount rules will work only for ‘vfat’ format. So the error message will be appeared if we
connect the other format. Refer section
for manual Block devices Test (SD/eMMC/USB host/SATA test)
mount of other formats.
17. How to manually partition SD card if sfdisk version is lesser than 2.26?
Please follow the below procedure only if the sfdisk version is lesser than 2.26

Download the source from https://www.kernel.org/pub/linux/utils/util-linux/
(download the required version. Here, util-linux-2.26.2.tar.gz is used) util-linux-2.26.2

Un-tar the downloaded source
$ tar -xvzf util-linux-2.26.2.tar.gz

Open the source code directory
$ cd util-linux-2.26.2

Run the Auto generation tool to find the dependency and prepare to build the source
~/util-linux-2.26.2 $ ./autogen.sh

If It displays errors due to missing dependencies, run the below command to fix missing
dependencies
~/util-linux-2.26.2 $ sudo apt-get install autopoint autoconf libtool automake gettext

Now execute configure and make commands to build the sfdisk
~/util-linux-2.26.2 $ ./configure; make

The generated sfdisk will be present in the same path.

Instead of installed sfdisk, use the newly compiled sfdisk with path for partitioning the SD card.
$ cd <android built path>/android_N7.1.1_1.0.0
$ vi ./device/fsl/common/tools/fsl-sdcard-partition.sh

Replace sfdisk with <path to util-linux-2.26.2>/ util-linux-2.26.2/sfdisk in the fsl-sdcard-partition.sh

Refer the section to proceed with partition. SD Card Partition
