Prepare Android System

This section presents the steps to prepare Android System for the VR Linux Board 5.0.

Prepare

The required tools include:

• Variscite development board - VAR_STK-MX6_V2-AO
• Recovery sd card, which comes with the development board
• Multi-function sd card reader with USB cable
• Parts waiting for flash: CPU module - VAR-SOM-MX6 REV2.11, Micro sd card - Sandisk Industrial 8G
• Linux computer

Check the device node of the attached SD card, which is in the form of /dev/sdbx. All steps below assume the usb device node is /dev/sdb

sudo sfdisk -l

Update Recovery SD card

Go to the top building output folder like "release-sd-2016-04-01T13:32:51". Insert the recovery sd card into the sd card reader. Copy all required files to the recovery sd card:

sudo ./var-mkemmc-vr.sh /dev/sdb2

Flash Variscite VAR-SOM-MX6

Put the updated recovery card to the development board, hold the center black button and turn on power switch. Then the development board will boot from the recovery card. After the system boots up, login as “root” without password.

If you have a brand new VAR-SOM-MX6 CPU module, you need partition, format first and then flash SPL.nand, u-boot-var-imx6-sd.img, boot- som-mx6q-vsc.img:

mksd_android_vr.sh

Flash Micro SD Card

As to a brand new micro sd card, you need to partition and format first, then flash files:

sudo ./var-mksdcard.sh -f som-mx6q-vsc /dev/sdb

As to an used micro sd card, if you want to keep current user data, just copy new-built files without partition and format:

sudo ./var-mksdcard-vr.sh som-mx6q-vsc /dev/sdb

First Boot

After you successfully flash mx6 module and sd card, at the first time when you boot up the Android system from the board, please run the command to do some settings:

vr-firstrun.sh

Flash MAC Address

After login the Android system from terminal, you need flash the MAC address on the board.

First to remount the Android file system to change from read only to read/write:

mount -o remount,rw /dev/block/mmcblk1p5 /system/

Then flash the MAC address, where "00:50:c2:7c:5f:6a" below is the MAC address as an example:

calibrator set nvs_mac /system/etc/firmware/ti-connectivity/wl1271-nvs.bin 00:50:c2:7c:5f:6a

Last, check the flashed new MAC address:

calibrator get nvs_mac /system/etc/firmware/ti-connectivity/wl1271-nvs.bin

Hostname

To get the hostname of the board, run the command from the terminal:

getprop | grep hostname

The result shows like:

[net.hostname]: [android-beb83184647d558]

The name in the second square bracket is the hostname.

To assign a new hostname to the device, you need remount the Android file system to change from read only to read/write:

mount -o remount,rw /dev/block/mmcblk1p5 /system/

then assign the new hostname:

echo "net.hostname=NEWHOSTNAME" >> /system/build.prop

where NEWHOSTNAME is the name you want to assign.

NXP NFC Test

Make sure the NFC tag reader is connected to the VR Linux board through the I2C connector - "FRONT" on board. The NFC driver and settings are initialized automatically while the system boots up.

From the home page of Android UI, enter App menu and open the app named TagInfo. Hold your test NFC card and approaching the tag reader, the app will update the tag information once it reads successfully.

MagTek Credit Card Swiper Test

Make sure the credit card swiper is connected to the VR Linux board through a standard USB port on board. The driver is loaded automatically.

From the home page of Android UI, enter App menu and open the app named MagTek. Select the "USB" label on the top right of the screen, then click connect. Now you can use the swiper. Swipe your test credit card. Then all information will be displayed on screen.

Configure Android

It will take a bit longer at the first time to boot Android.
