Introduction
The purpose of this document is to provide a practical introduction on
evaluating ndroid 4.4.2 for the MOS-820 (Bare board: V B-820 Freescale
i.MX6 Quad).
1.1. Overview
The VI V B-820 platform is an embedded system powered by RM
processor with ndroid 4.4.2 operating system by default. V B-820’s ndroid
BSP offers a development package. Users can develop it under an Ubuntu
environment.
There are four major boot components for ndroid, the “

boot.img” “system.img”
” “system.img” ” “system.img”
” “system.img” and “recovery.img”
“recovery.img” “recovery.img”
“recovery.img”. The system will not boot
successfully into an ndroid environment if one of these files does not exist in
the boot media.

V B-820 ndroid BSP only supports booting from onboard eMMC. This
section will guide you through making the ndroid system boot media for
V B-820 from EVK folder.
2.1. Requirements
Linux development computer
Micro SD storage card. Recommended size is 4GB, class 4 at least.
EVK folder
2.2. Procedure
Step 1
Step 1Step 1
Step 1
Insert the Micro SD card to your Linux development computer.
Step 2
Step 2Step 2
Step 2
Open the “
““
“Terminal
TerminalTerminal
Terminal”
””
” utility.
Step 3
Step 3Step 3
Step 3
The Micro SD storage card can be identified and auto mounted once inserted
to the computer. You can check Micro SD card code name by $ df
$ df $ df
$ df -
--
-h
hh
h
user@ubuntu:~$ df –h
...
Filesystem Size Used Avail Use% Mounted on
/dev/sdb1 7.2G 531M 6.3G 8% /media/usb
However, there are some instances that the Micro SD storage card cannot be
identified or auto mounted after inserting to the computer. In that case, you
can try the other way to identify the Micro SD card.
user@ubuntu:~$ dmesg | grep –i removable
[105.502517] sd 9:0:0:0 [sdb] Attached SCSI removable disk

3
The Micro SD storage card code name for this example is identified as sdb
sdbsdb
sdb.
Step 4
Step 4Step 4
Step 4
The EVK path for this example is /home/user/EVK
/home/user/EVK/home/user/EVK
/home/user/EVK, user can enter the folder
“
““
“Images_autoinstall_sd/scripts
Images_autoinstall_sd/scriptsImages_autoinstall_sd/scripts
Images_autoinstall_sd/scripts”
””
” which is under EVK
EVKEVK
EVK.
user@ubuntu:~$ sudo cd /home/user/EVK/Images_autoinstall_sd/scripts
user@ubuntu:~/EVK/Images_autoinstall_sd/scripts$ ls
mk_install_sd.sh
Step 5
Step 5Step 5
Step 5
User can run the script “
““
“mk_install_sd.sh
mk_install_sd.shmk_install_sd.sh
mk_install_sd.sh”
””
” to make a bootable Micro SD card.
Thus, user can install the ndroid image into V B-820 eMMC through the
Micro SD card. The target Micro SD storage card code name for this example
is identified as sdb
sdbsdb
sdb.
user@ubuntu:~/EVK/Images_autoinstall_sd/scripts$
sudo ./mk_install_sd.sh /dev/sdb
User can unplug the Micro SD card from Linux development PC after the
message “Done!
Done!Done!
Done!” appears.
Step 6
Step 6Step 6
Step 6
Insert the Micro SD card into V B-820. Make sure to set the jumper setting to
make it bootable from Micro SD. For more details about the boot select
jumper, please refer to the V B-820 User Manual.

Notes:
1. It is recommen e to connect COM2 ebug cable to make sure the U-boot parameter is correct.
2. Make sure the U-boot parameter is clean. User can type the comman below in U-boot:
u-boot> estroyenv
u-boot> reset
Here, the V B-820 should boot into Linux.
Step

Type this command to format/partition/flash ndroid image into SPI/eMMC.
$./fsl-eMMC-partition.sh –f /dev/mmcblk0
The U-boot will flash into SPI ROM and the others will flash into eMMC.
Shutdown Linux by this command
$poweroff

Set the J11 jumper (short pin 2-3) to SPI booting selection. Then power on the
V B-820 and set U-boot parameter through COM2 debug port.
For more details about the boot select jumper, please refer to the V B-820
User Manual.
Make sure the U-boot parameter is clean. User can type the command below
in U-boot:
u-boot> destroyenv
u-boot> reset

Setting U-boot parameter for eMMC.
Connect the V B-820 and host PC through J5 (COM2) of V B-820. Run
“putty” on host PC to receive the booting message. Power on the V B-820
and press any key to stop the booting process as shown in Figure 3.

[HDMI]
To set HDMI as boot display:
setenv display run hdmi
To set HDMI resolution:
setenv hdmi ‘setenv bootargs ${bootargs}
video=mxcfb0:dev=hdmi,1920x1080M@60,bpp=32 video=mxcfb1:off
video=mxcfb2:off video=mxcfb3:off fbmem=28M vmalloc=400M
androidboot.hardware=freescale audio=hdmi’
To replace the resolution, change the red color part with the desired
resolution mode.
For example: To set the 1280 x 720, change the 1920 x 1080 to 1280 x 720.
setenv hdmi ‘setenv bootargs ${bootargs}
video=mxcfb0:dev=hdmi,1280x720M@60,bpp=32 video=mxcfb1:off
video=mxcfb2:off video=mxcfb3:off fbmem=28M vmalloc=400M
