Initial steps
Install Prerequisites
sudo apt-get install wget sudo apt-get install e2fsprogs sudo apt-get install util-linux
Create working directory
mkdir -pv ~/workdir/imx6/android/ cd ~/workdir/imx6/android/
Download installation files
git clone https://github.com/voipac/imx6_rex_bin_kk442 cd imx6_rex_bin_kk442/
SD card partition layout
This will be the final SD card partitioning layout at the end of installation procedure:
| Partition type/index | Name | Start offset | Size | File system | Content |
|---|---|---|---|---|---|
| N/A | BOOT Loader | 1 KB | 1 MB | N/A | Not used |
| Primary 1 | Boot | 8 MB | 8 MB | boot.img format, kernel + ramdisk | boot.img |
| Primary 2 | Recovery | Follow Boot | 8 MB | boot.img format, kernel + ramdisk | recovery.img |
| Logic 5 (Extended 3) | SYSTEM | Follow Recovery | 512 MB | EXT4. Mount as /system | system.img |
| 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 | 4 MB | N/A | For recovery store 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 |
Install Bootloader
Download the image file
wget http://downloads.voipac.com/files/iMX6_Rex_Development_Kit/module/software/android/Android_kk442/binaries/u-boot-0x27800000_imx6q_20160410.bin
Flash the bootloader into SPI memory
mw.b 0x10800000 0xFF 0x80000 tftp 0x10800000 u-boot-0x27800000_imx6q_20160410.bin sf probe 3:2 sf erase 0x0 0x80000 sf write 0x10800000 0x0 0x80000
Install Android
Extract system.img
7z x system.img.7z.001
Creating SD card
Note: Unmounted SD card during this process is essential otherwise the fsl-sdcard-partition script may fail to create a proper Android SD card.
For installation SD card partition script is used:
- This script requires boot.img, recovery.img and system.img files in the same directory as script itself
- /dev/mmcblk0 is the path to the SD card
Note: The script is working correctly only with /dev/mmcblk0 devices (USB to SD adaptors will not work).
chmod a+x fsl-sdcard-partition.sh sudo ./fsl-sdcard-partition.sh -f /dev/mmcblk0
