Overview
The following outlines the procedure necessary to install Android on the CompuLab CM-QS600 System-on-Module / Computer-on-Module.
Installation target media
CM-QS600 uses on-board eMMC as root file system medium.
|
Additional media might be enabled in the coming releases. |
Installation onto eMMC
Preconditions
- CM-QS600 evaluation kit.
- PC workstation with installed fastboot client software.
- Connect HDMI display to the CM-QS600 (optional).
- Connect serial console to the CM-QS600 (optional).
- Connect USB cable between the CM-QS600 USB OTG (P7) jack and PC workstation, in order to enable fastboot protocol.
- Connect RTC battery to P15.
Flashing Android image
- Download prebuilt Android image.
- Decompress the file, in order to get Android partition images.
- Enter fastboot mode following either of the options:
- There is no valid boot partition (which is how CM-QS600 comes out of the box).
- In this case, the device will enter fastboot mode upon power on.
- There is a valid boot partition (i.e. CM-QS600 was pre-installed with OS).
- In this case, the device will boot from it.
- Accessing Android command line, one can observe and then destroy boot partition signature ("ANDROID"), effectively making boot partition invalid, going back to option 1 after reboot.
# dd if=/dev/block/platform/msm_sdcc.1/by-name/boot bs=1 count=7
# echo -n "X" | dd of=/dev/block/platform/msm_sdcc.1/by-name/boot bs=1 count=1
- Flash each partition image file to the eMMC with the aid of fastboot utility:
$ fastboot flash boot boot.img $ fastboot flash system system.img $ fastboot flash cache cache.img $ fastboot flash userdata userdata.img
- Proceed to boot, issuing
$ fastboot reboot
Boot
- Power on
- Within 3 seconds the device should start booting into Android.
- Within 60 seconds the HDMI display should start showing signs of life.
