Step 1: Read about the Fastboot Method

Fastboot is supported by the board and can be used for installs. This is for advanced users who are most likely modifying/customizing source code and will need to download such updates to the board for test/execution.

This method requires the following hardware:

  • DragonBoard™ 410c with power supply
  • Host machine (Linux, Mac OS X, or Windows)
  • USB to microUSB cable
  • USB Mouse and/or keyboard (not required to perform flash)
  • HDMI Monitor with full size HDMI cable (not required to perform flash)

Step 2: Download Android Bootloader and Boot file

Note the location of all downloads, they will be needed once you access your instruction set

Step 3: Download all remaining files

Note the location of all downloads, they will be needed once you access your instruction set

Step 4: Install Android using Fastboot with Linux host

This section show how to install the Android operating system to your DragonBoard™ 410c using the fastboot method on a Mac OS X host computer.

1 - Make sure fastboot is set up on host computer

  • Android SDK “Tools only” for Linux can be downloaded here
  • The Linux “Tools Only” SDK download does not come with fastboot, you will need to use the Android SDK Manager to install platform-tools.
  • To do this follow the “SDK Readme.txt” instructions included in your SDK “Tools Only” download.

2 - Connect host computer to DragonBoard™ 410c

  • DragonBoard™ 410c must be powered off (unplugged from power)
  • Make sure microSD card slot on DragonBoard™ 410c is empty
  • S6 switch on DragonBoard™ 410c must be set to ‘0-0-0-0’. All switches should be in “off” position
  • Connect USB to microUSB cable from host computer to DragonBoard™ 410c

3 - Boot DragonBoard™ 410c into fastboot mode

Please read all bullet points before attempting

  • Press and hold the Vol (-) button on the DragonBoard™ 410c, this is the S4 button. DragonBoard™ 410c should still NOT be powered on
  • While holding the Vol (-) button, power on the DragonBoard™ 410c by plugging it in
  • Once DragonBoard™ 410c is plugged into power, release your hold on the Vol (-) button.
  • Board should boot into fastboot mode.

From the connected host machine terminal window, run the following commands:

# Check to make sure device is connected and in fastboot mode

fastboot devices

At this point you should be connected to your DragonBoard™ 410c with a USB to microUSB cable. Your DragonBoard™ 410c should be booted into fastboot mode and ready to be flashed with the appropriate images.

4 - Flash Bootloader

  • Use host computer
  • Open "Terminal" application
  • Recall location of Bootloader download.
  • The bootloader file should be named dragonboard410c_bootloader_emmc_android
  • cd to the directory with your unzipped Bootloader Folder
cd <extraction directory>

#Example: 
cd /Users/YourUserName/Downloads
#<extraction directory> = /Users/YourUserName/Downloads
#For this example we assume the "Bootloader" is in the Downloads folder.


cd <unzipped Bootloader folder>

#Example:
cd dragonboard410c_bootloader_emmc_android
#<unzipped Bootloader folder> = dragonboard410c_bootloader_emmc_android

# This command will execute the flashall script within the bootloader folder
./flashall

5 - Recall location of all downloaded files from downloads page

This will include the files listed below:

Reference Platform files
  • boot.img.tar.xz
  • system.img.tar.xz
  • userdata.img.tar.xz
  • cache.img.tar.xz

6 - Unzip all files

7 - Flash all files to the DragonBoard™ 410c

  • Use host computer
  • Use "Terminal" application
  • Recall location of all extracted(unzipped) files
  • cd to the directory with your unzipped files
  • From within extraction directory, execute the following commands:
Reference Platform
# (Once again) Check to make sure fastboot device connected
sudo fastboot devices

# cd to the directory the boot image and  were extracted
$ cd <extraction directory>

# Make sure you have properly unzipped the downloads
sudo fastboot flash boot boot.img
sudo fastboot flash system system.img
sudo fastboot flash userdata userdata.img
sudo fastboot flash cache cache.img

8 - Reboot DragonBoard™ 410c

  • Unplug power to DragonBoard™ 410c
  • Unplug micro USB cable from DragonBoard™ 410c
  • Ensure HDMI connection to monitor
  • Ensure keyboard and/or mouse connection (Depending on your rootfs selection)
  • Plug power back into DragonBoard™ 410c
  • Wait for board to boot up
  • Board will boot into Android lock screen.

Congratulations! You are now booting your newly installed OS directly from eMMC on the DragonBoard™ 410c!
