Step 1: Prepare MicroSD card

• Ensure data from microSD card is backed up
• Note: Everything on microSD card will be lost by the end of this procedure.

Step 2: Find SD Card Device name

• You may need a MicroSD card adapter if your host computer only has an SD card slot
• On the host computer, open “Terminal” application (Press Command+Space bar and type “Terminal”)
• Remove SD card from host computer and run the following command:

  diskutil list

  
  

Note all recognized disk names (example: /dev/disk1)

Insert SD card and run the following command (again):

diskutil list

Note the newly recognized disk. This will be your SD card.

Remember your SD card device name, it will be needed in Step 7.

Step 3: Recall Download Location

• Locate SD card install file that you got from Downloads page.
• This file will be needed for the next step.

Step 4: Unzip SD Card Install Image

• Uncompress or unzip the SD Card Install Image . With Mac OS X, you can use the Finder app to locate the file and then double click to automatically unzip the file.
• When unzipped, a folder (ex: dragonboard410c_sdcard_install_debian-83) will be created with the following contents:
  • An install Image (.img) (ex: db410c_sd_install_debian.img)
  • Readme or license.txt

Step 5: Go to directory with SD Card Install Image folder using Terminal

• On the host computer, open the “Terminal” application (Press Command+Space bar and type “Terminal”)
• cd to the directory with your unzipped SD Card Install Image

cd <extraction directory>

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

Step 6: Locate SD Card Install Image 
Make sure you are in the extraction directory
 
Unzipped SD Card download will be a folder. 
This folder should be found in your directory. 
Type ls from command line for a list of files that can be found in your current directory:

ls

#output
dragonboard410c_sdcard_install_Y-XX
 
Unzipped folder should be called 
dragonboard410c_sdcard_install_Y-XX, where Y can be Android or Debian 
and XX represents the release number
 
 cd into this directory
 
cd dragonboard410c_sdcard_install_Y-XX
 
Inside this folder you will find the install image where Y is Android or Debian. 
 
db410c_sd_install_Y.img
 
This .img file is what will be flashed or copied to your SD Card.
 Step 7: Flash Image onto SD Card 
Checklist: 
SD card inserted into host computer
 
Recall SD Card device name from Step 2 
 
From within the dragonboard410c_sdcard_install_Y-XX folder, using the Terminal execute the following commands:
 
 
Execute:
$ sudo dd if=db410c_sd_install_Y.img of=/dev/XXX bs=4m
$ sudo sync
Note:
 
 
 if=db410c_sd_install_Y.img: should match the name of the image that was downloaded.
 
 of=/dev/XXX: XXX should match the name of the SD Card device name from Step 2. Be sure to use the device name without the partition name. For example, ‘of=/dev/disk1’
 
If you get an error message “Resource Busy”, you will need to unmount the SD card without removing it from the host computer. 
 
Option 1:
 
In the Applications folder, find and click on the Utilities folder.
 
Click on the Disk Utility program to run it
 
Select the device that represents the SD card
 
Click on unmount and leave the SD card in the computer
 
Retry the ‘$ sudo dd if=db410c_sd_install_Y.img of=/dev/XXX bs=4m’
 
Option 2:
 
In the terminal window, enter this command:
 
$ sudo umount /dev/<device name>
 

This command will take some time to execute. Be patient and avoid tampering with the terminal until process has ended.
 
Once SD card is done flashing, remove from host computer and set aside for Step 8 You may see a popup window that tells you the device is Not readable by the operating system. Ignore the message and remove the MicroSD card from the host computer.
 
 
 Step 8: Prepare DragonBoard 410c with SD card
 
 
Make sure DragonBoard™ 410c is unplugged from power
 
Set S6 switch on DragonBoard™ 410c to 0-1-0-0, “SD Boot switch” should be set to “ON”. 
 
Please see “1.1 Board Overview” on page 7 from DragonBoard™ 410c Hardware Manual if you cannot find S6
 
 
 
Connect an HDMI monitor to the DragonBoard™ 410c with an HDMI cable, and power on the monitor
 
Plug a USB keyboard and/or mouse into either of the two USB connectors on the DragonBoard™ 410c
 
Insert the microSD card into the DragonBoard™ 410c
 
Plug power adaptor into DragonBoard™ 410c, wait for board to boot up.
 
 
 Step 9: Install image onto DragonBoard 410c



 
If Steps 1 - 8 were followed correctly, the above screen should be visible from your DragonBoard™ 410c
 
Select the image to install and click “Install” (or type “i”). OS will be installed into the eMMC memory
 
This process can take a few minutes to complete
 
Upon completion, “Flashing has completed and OS has installed successfully….” message will appear.
 
 
Before clicking “OK”:
 
 
Remove the SD Card
 
Set S6 switch on DragonBoard™ 410c to 0-0-0-0, all switches should be set to “OFF”
 
Now click “OK” button and allow DragonBoard™ 410c to reboot.
 
 
Congratulations! 
You are now booting your newly installed operating system directly from eMMC on the DragonBoard™ 410c!
