Dragonboard™ 410c Linux Installation Guide

This Users Guide provides a general overview for getting started with Linux installations on the DragonBoard™ 410c.

There are two primary ways to install software onto the DragonBoard™ 410c:

  • SD Card
  • Fastboot

Making your way through this document is easy!

  1. Read about both installation methods
  2. Choose your method
  3. Choose your host machine (This is the machine you will be using throughout the process)
  4. Follow your custom set of steps

If you are having trouble with this document please click here for a video walkthrough.


Step 1: Read about both installation methods

SD Card Method

The SD card method allows you to place a microSD card into the DragonBoard™ 410c to automatically boot and install the Linux Desktop onto the board. This method is generally simpler and should be used by beginners.

This method requires the following hardware:

  • DragonBoard™ 410c with power supply
  • Host machine (Linux, Mac OS X, or Windows)
  • MicroSD card with 4GB or more of storage
  • USB Mouse and/or keyboard
  • HDMI Monitor with full size HDMI cable

Skip to the Install Debian Using SD Card section to use this method.

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. When installing Debian using Fastboot, you will have the option to install either the Developer(console-only) image, or the LXDE(Desktop) image.

Note: When installing Debian using the SD Card method, LXDE(Desktop) install is currently the only option, Fastboot is the only way to attain a Console-only Debian install.

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)

Skip to the Install Debian Using Fastboot to use this method.

Step 3: Choose your Host Machine


Linux Host

This section is intended for users who would like to use the SD Card Method for Linux installation with their Linux host machine.

Please watch this optional video tutorial if you are having trouble following the document.

Getting Started

This section builds the SD Card image for the DragonBoard™ 410c. The steps in this section are executed entirely from the host PC. It is assumed that the developer is using a Linux development host.

Step 1: Prepare MicroSD card

Make sure you have backed up all valuable data from SD card. Everything on SD card, prior to flashing Linux image, will be lost by the end of this procedure.

Step 2: Download Debian SD Card Install Image

Step 3: Unzip the downloaded install file

Note the directory the install image was extracted to, as this will be required in the next step. There are multiple tools to unzip and extract these archives.

Your SD card and install file should be ready! In the next section we will flash your install file onto your SD card.

Install Image onto SD Card

Note: SD card does not need to be formatted in any special way since this procedure will write the entire image, including the partition table.

From the command prompt on the host PC, enter the following sequence of commands:

# cd to the directory the install file was extracted to
$ cd <extraction directory>

$ sudo dd if=db410c_sd_install_debian-YY.img of=/dev/XXX bs=4M oflag=sync status=noxfer

Warning: Executing the sync flag command as outlined above is very important! Do not skip this step!

Warning: Be very careful not to overwrite your hard drive! In most cases, XXX will be mmcblk0 or sdb.

YY is Debian release number of downloaded file XXX is the SD card device name (Click here for instructions on how to find microSD card device name)

Flashing your SD card could take several minutes. Please be patient. When SD card is done flashing, eject device and move to the next section.

Flashing SD Card Image to the DragonBoard™ 410c

Once the image is written on the SD Card per the previous section, perform the following steps to flash the image into the eMMC memory on the DragonBoard™ 410c:

Install Debian Using Fastboot

Back to Step 2

Step 3: Choose your Host Machine


##Linux Host

Getting Started

This section will explain the fastboot method for installation of the Linux images onto the DragonBoard™ 410c.

Please watch this optional video tutorial if you are having trouble following the document.

This is for advanced users that plan to be flashing many versions of the OS into the DragonBoard™ 410c.

Prerequisites:

Before we can start flashing the appropriate files onto you DragonBoard™ 410c:

  • You will need to acquire the appropriate tools (ADB and Fastboot).
  • You will need to know how to boot the DragonBoard™ 410c up into fastboot mode.
  • You will need to download all files necessary for install.

Since the bootloader on this board supports fastboot. The developer should only have to focus on getting fastboot installed on his/her host PC.

The following steps will walk you through the download and installation of Fastboot onto your host MAC OS X machine:

Step 1: Download latest version of the adb-fastboot-install file here

Clicking the link above will download the appropriate file into your "Downloads" folder.

Step 2: Open your terminal by pressing Command+Space and typing in Terminal. Execute the following commands:

# cd to the directory the ADB and Fastboot file were extracted to, this will most likely be your Downloads folder

$ cd <extraction directory>
$ cd Android
$ ./ADB-Install-Linux.sh

# This command will require root permission, enter your password

You have now moved both ADB and Fastboot to your /usr/bin, this will allow them utilized from anywhere in your terminal.

Simply type fastboot or adb from your terminal command line to make sure everything is working properly.

Step 3: Now that we are set up we will need to connect our host machine to our DragonBoard™ 410c and boot into Fastboot mode.

**Connect your host machine to your DragonBoard™ 410c using a USB to microUSB cable and follow these instructions:

  • Micro SD Card slot on DragonBoard™ 410c must be empty
  • S6 switch on the DragonBoard™ 410c must be set to: 0-0-0-0 {All switches in off position}
  • Press and hold the Vol (-) button on the DragonBoard™ 410c {S4}, DragonBoard™ 410c should not be powered on yet
  • While pressing S4 button, power up the DragonBoard™ 410c by plugging it in
  • Release your hold on S4 button within a few seconds of powering on. Board should boot into Fastboot mode.

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

# Check to make sure fastboot device connected.
$ 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.


Flash Bootloader into on-board eMMC

In this section we will continue by downloading and flashing the bootloader onto your DragonBoard™ 410c. This will be achieved by accessing and executing a script located in the bootloader download folder.

Step 1: Download

Bootloader zip

Step 2: Flash Bootloader

Open up terminal and execute the following commands:

# cd to the directory the bootloader zip file was extracted
cd <extraction directory>

sudo ./flashall

The bootloader is now installed on the DragonBoard™ 410c!


Flash Linaro/Debian Release

In this section we will flash all remaining parts of the operating system. In order to do this we will be using the fastboot commands that are now readily available to us in our Terminal command line.

Step 1: Download boot and rootfs

The way you experience this operating system will be based on which rootfs you choose for your board. Once downloaded, their names should be similar to what you see here:

Debian boot image: boot-linaro-jessie-qcom-snapdragon-arm64-BUILD#.img.gz

Developer rootfs: linaro-jessie-developer-qcom-snapdragon-arm64-BUILD#.img.gz

or

ALIP-Desktop rootfs: linaro-jessie-alip-qcom-snapdragon-arm64-BUILD#.img.gz

Where BUILD# is the date/Build stamp for the downloaded file

Step 2: Flash 'boot' and 'rootfs' to DragonBoard™ 410c

Flash the boot image and rootfs to the DragonBoard™ 410c by executing the following commands from the host PC:

# Check to make sure fastboot device connected.  If not resolve
$ sudo fastboot devices

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

# Make sure you have properly unzipped the boot and rootfs downloads
sudo fastboot flash boot boot-linaro-jessie-qcom-snapdragon-arm64-**BUILD#**.img
sudo fastboot flash rootfs linaro-jessie-developer-qcom-snapdragon-arm64-**BUILD#**.img

Note: Replace BUILD# in the above commands with the file-specific date/build stamp.

Now reboot the DragonBoard™ 410c using the following sequence and it will boot to the command prompt:

  • Unplug the power to the DragonBoard™ 410c
  • Unplug the micro USB fastboot cable
  • Make sure you are plugged in to a HDMI monitor, keyboard and/or mouse depending on your rootfs
  • Plug the power back into the DragonBoard™ 410c

Note: the username and password are both “linaro” when the login information is requested.

Enjoy your new operating system!

Step 3: Insert SD card and run command again

Code:

$ diskutil list

Sample print out:

MacUser$ diskutil list

/dev/disk2 (internal, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER

   1:               Windows_NTFS Untitled                31.9 GB    disk2s1

Notice our sample print out is now detecting a new device as IDENTIFIER disk2 with partition disk2s1:

/dev/disk2 (internal, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:     FDisk_partition_scheme                        *31.9 GB    disk2
   1:               Windows_NTFS Untitled                31.9 GB    disk2s1

It is important to notice and compare the characteristics of the device to what we know about the device. In our sample we have a type Windows_NTFS, 31.9G device. Our host PC has assigned it a device name of disk2 with a partition of `disk2s1. Your device name can vary, this is why you should check your list of devices before and after inserting the SD card.

It's time to continue with the flashing process.
