How to test Android on iMX6 Rex

To prepare an Android SD card, you will need a host machine with Linux. If you don’t have any Linux machine, you can follow these steps to prepare one. Once you have the host machine, login in and follow the steps below.

Create a directory called Android:

cd

mkdir android

cd android

Download all the files you will need:

wget http://www.voipac.com/downloads/imx/iMX6_Rex/Module/bin/android/kk442/u-boot-pro-20141211.bin

wget http://www.voipac.com/downloads/imx/iMX6_Rex/Module/bin/android/kk442/boot-20141211.img

wget http://www.voipac.com/downloads/imx/iMX6_Rex/Module/bin/android/kk442/recovery-20141211.img

wget http://www.voipac.com/downloads/imx/iMX6_Rex/Module/bin/android/kk442/system-20141211.img

wget http://wiki.voipac.com/xwiki/bin/download/rex/android442/fsl%2Dsdcard%2Dpartition.sh

chmod 777 fsl-sdcard-partition.sh

Note: To download the latest VOIPAC Android files, check their website at: http://wiki.voipac.com/xwiki/bin/view/imx6+rex/android442

Rename the files:

mv u-boot-pro-20141211.bin u-boot.bin

mv boot-20141211.img boot.img

mv recovery-20141211.img recovery.img

mv system-20141211.img system.img

Insert an SD card into your host and check how it was recognized:

fedevel@ubuntu:~/android$ dmesg | tail

In our case, the card is under /dev/sdb.

Before you go further, be sure the sd card ( /dev/sdb ) is not mounted otherwise the fsl-sdcard-partition script may fail to create a proper Android SD card.

fedevel@ubuntu:~/android$ sudo umount /media/data/

fedevel@ubuntu:~/android$

The safest way to continue is to use fdisk and delete all the partitions on your SD card. The next steps will delete all the files from SD card:

fedevel@ubuntu:~/android$ sudo fdisk /dev/sdb

fedevel@ubuntu:~/android$

Now you can run the script:

sudo ./fsl-sdcard-partition.sh -f /dev/sdb

After it’s finished, remove the SD card from host and insert it into your iMX6 Rex Development Baseboard. Use the SD slot on the edge of the PCB. Power up the board, cancel booting process in uBoot and run the following command:

mw.l 0x020d8040 0x3040; mw.l 0x020d8044 0x10000000; reset

Cancel uBoot booting (e.g. press enter) and now …

Booting Android to HDMI

If you would like to boot up to a HDMI Monitor, put these commands into the “second” u-Boot (the uBoot which comes up after the “mw.l 0x020d8040 0×3040; mw.l 0x020d8044 0×10000000; reset” command):

setenv machid 12a9

setenv bootargs console=ttymxc0,115200 init=/init video=mxcfb0:dev=hdmi,1280x720M@60,if=RGB666 video=mxcfb1:off video=mxcfb2:off fbmem=28M vmalloc=400M androidboot.console=ttymxc0 androidboot.hardware=freescale

booti mmc1

Note: If you dont have a touchscreen and you need to see the mouse cursor, you may need to unplug and plug your USB mouse and you may need to press “Enter” (or just move a mouse) and cursor will come up on the HDMI monitor.

Booting Android to LVDS

If you would like to boot up to an LVDS Display, put these commands into the “second” u-Boot (the uBoot which comes up after the “mw.l 0x020d8040 0×3040; mw.l 0x020d8044 0×10000000; reset” command):

setenv machid 12a9

setenv bootargs console=ttymxc0,115200 init=/init video=mxcfb0:dev=ldb,LDB-ETV570,if=RGB666 vmalloc=400M fbmem=28M fbcon=28M androidboot.console=ttymxc0 androidboot.hardware=freescale

booti mmc1
