On this page you can find step-by-step instructions about how to test Android on iMX6 Rex. Credit goes to VOIPAC. Thank you.
For more information, follow VOIPAC wiki website at:
http://wiki.voipac.com/xwiki/bin/view/imx6+rex/android442
Android source code for iMX6 Rex can be downloaded from here: http://www.voipac.com/downloads/imx/iMX6_Rex/Module/src/android/kk442/
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 [2300997.840777] sd 36:0:0:0: [sdb] No Caching mode page found [2300997.840782] sd 36:0:0:0: [sdb] Assuming drive cache: write through [2300997.865395] sdb: sdb1 sdb2 sdb3 < sdb5 sdb6 sdb7 sdb8 > sdb4 [2300997.865913] sdb: p4 size 5567104 extends beyond EOD, truncated [2300998.787584] EXT4-fs (sdb7): mounted filesystem with ordered data mode.

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$ mount /dev/sda1 on / type ext4 (rw,errors=remount-ro) proc on /proc type proc (rw,noexec,nosuid,nodev) sysfs on /sys type sysfs (rw,noexec,nosuid,nodev) none on /sys/fs/fuse/connections type fusectl (rw) none on /sys/kernel/debug type debugfs (rw) none on /sys/kernel/security type securityfs (rw) udev on /dev type devtmpfs (rw,mode=0755) devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620) tmpfs on /run type tmpfs (rw,noexec,nosuid,size=10%,mode=0755) none on /run/lock type tmpfs (rw,noexec,nosuid,nodev,size=5242880) none on /run/shm type tmpfs (rw,nosuid,nodev) vmware-vmblock on /run/vmblock-fuse type fuse.vmware-vmblock (rw,nosuid,nodev,default_permissions,allow_other) gvfs-fuse-daemon on /home/fedevel/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=fedevel) /dev/sdb7 on /media/vender type ext4 (rw,nosuid,nodev,uhelper=udisks) /dev/sdb5 on /media/57f8f4bc-abf4-655f-bf67-946fc0f9f25b type ext4 (rw,nosuid,nodev,uhelper=udisks) /dev/sdb6 on /media/cache type ext4 (rw,nosuid,nodev,uhelper=udisks) /dev/sdb4 on /media/data type ext4 (rw,nosuid,nodev,uhelper=udisks) fedevel@ubuntu:~/android$ sudo umount /media/vender/ fedevel@ubuntu:~/android$ sudo umount /media/57f8f4bc-abf4-655f-bf67-946fc0f9f25b/ fedevel@ubuntu:~/android$ sudo umount /media/cache/ 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 Command (m for help): p Disk /dev/sdb: 3965 MB, 3965190144 bytes 122 heads, 62 sectors/track, 1023 cylinders, total 7744512 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdb1 15128 37819 11346 83 Linux /dev/sdb2 37820 60511 11346 83 Linux /dev/sdb3 60512 2276763 1108126 5 Extended /dev/sdb4 2276764 7843867 2783552 83 Linux /dev/sdb5 60513 1111907 525697+ 83 Linux /dev/sdb6 1111909 2163303 525697+ 83 Linux /dev/sdb7 2163305 2185995 11345+ 83 Linux /dev/sdb8 2185997 2208687 11345+ 83 Linux Command (m for help): d Partition number (1-8): 8 Command (m for help): d Partition number (1-7): 7 Command (m for help): d Partition number (1-6): 6 Command (m for help): d Partition number (1-5): 5 Command (m for help): d Partition number (1-5): 4 Command (m for help): d Partition number (1-5): 3 Command (m for help): d Partition number (1-4): 2 Command (m for help): d Selected partition 1 Command (m for help): w The partition table has been altered! Calling ioctl() to re-read partition table. Syncing disks. 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
