=== Preparing SD card ===
<syntaxhighlight lang="bash">
mkdir -pv ~/workdir/imx6/android/bin/7_1/tinyrex
cd ~/workdir/imx6/android/bin/7_1/tinyrex
wget -r -nH -nd -np -R index.html* http://downloads.voipac.com/index.php?p=iMX6_OpenRex_SBC/software/android/Android_7_1/binaries
chmod a+x vpac-sdcard-partition.sh
</syntaxhighlight>

==== SD card partition layout ====
This will be the final SD card partitioning layout at the end of installation procedure:

{| class="wikitable"
! Partition type/index !! Name !! Start offset !! Size !! File system !! Content
|-
| N/A|| BOOT Loader|| 1 KB|| 1 MB|| N/A|| bootloader
|-
| Primary 1|| Boot|| 8 MB|| 32 MB|| boot.img format, kernel + ramdisk|| boot.img
|-
| Primary 2|| Recovery|| Follow Boot|| 32 MB|| boot.img format, kernel + ramdisk|| recovery.img
|-
| Logic 5 (Extended 3)|| SYSTEM|| Follow Recovery|| 1536 MB|| EXT4. Mount as /system|| system.img (Android system files under /system/ dir)
|-
| Logic 6 (Extended 3)|| CACHE|| Follow SYSTEM|| 512 MB|| EXT4. Mount as /cache || Android cache for image store of OTA
|-
| Logic 7 (Extended 3)|| Device|| Follow CACHE|| 8 MB|| EXT4. Mount as /vender|| To Store MAC address files
|-
| Logic 8 (Extended 3)|| Misc|| Follow Device|| 6 MB|| N/A|| For recovery store bootloader message, reserve
|-
| Logic 9 (Extended 3)|| DATAFOOTER|| Follow Misc|| 2 MB|| N/A|| For crypto footer of DATA partition encryption bootloader message, reserve
|-
| Primary 4|| DATA|| Follow Misc|| Total - Other images|| EXT4. Mount at /data|| Application data storage for the system application and for internal media partition in /mnt/sdcard/ dir
|}

==== Creating SD card ====
Based on the location where the SD card has been mounted alter and use one of these commands:
<syntaxhighlight lang="bash">
sudo ./vpac-sdcard-partition.sh -f imx6openrex ultra /dev/mmcblkX
</syntaxhighlight>
or
<syntaxhighlight lang="bash">
sudo ./vpac-sdcard-partition.sh -f imx6openrex ultra /dev/sdX
</syntaxhighlight>

=== Setup ===
==== Bootloader ====
Android bootloader is stored in SD card and directly executed. Additional configurations are not required.

==== Chainloading SD card bootloader ====
<syntaxhighlight lang="bash">
setenv bootcmd "bmode esdhc2"
saveenv
reset
</syntaxhighlight>

==== Setting HDMI video output ====
<syntaxhighlight lang="bash">
setenv bootargs "console=ttymxc0,115200 init=/init video=mxcfb0:dev=hdmi,if=RGB24,bpp=32 video=mxcfb1:off vmalloc=128M androidboot.console=ttymxc0 consoleblank=0 androidboot.hardware=freescale cma=320M"
saveenv
</syntaxhighlight>

==== Setting LVDS video output ====
<syntaxhighlight lang="bash">
setenv bootargs "console=ttymxc0,115200 init=/init video=mxcfb0:dev=ldb,edt570,if=RGB666 video=mxcfb1:off vmalloc=128M androidboot.console=ttymxc0 consoleblank=0 androidboot.hardware=freescale cma=320M"
saveenv
