Linux Host
**What is a Linux Host?**
A Linux host is a computer that is running the Linux operating system. Linux is a free and open-source operating system that is popular among developers and power users. Linux is also used on a variety of embedded devices, such as the DragonBoard 410c.
**What are the advantages and disadvantages of a Linux host?**
**Advantages:**
* Linux is a free and open-source operating system.
* Linux is very versatile and can be used on a variety of devices.
* Linux is very stable and secure.
* Linux is highly customizable.
**Disadvantages:**
* Linux can be more difficult to use than other operating systems, such as Windows and macOS.
* Linux may not have all of the software that is available for other operating systems.
* Linux may not have as much support as other operating systems.
**How to install an operating system on a DragonBoard 410c using a Linux host**
To install an operating system on a DragonBoard 410c using a Linux host, you will need the following:
* A Linux host computer
* A DragonBoard 410c
* A microSD card
* An HDMI cable
* A USB keyboard and/or mouse
* A power adapter for the DragonBoard 410c
Once you have all of the necessary items, follow these steps:
1. Prepare the microSD card.
2. Find the SD card device name.
3. Recall the download location of the operating system image.
4. Unzip the operating system image.
5. Go to the directory with the unzipped operating system image.
6. Locate the operating system image file.
7. Install the operating system image to the microSD card.
8. Prepare the DragonBoard 410c with the microSD card.
9. Install the operating system image to the DragonBoard 410c.
**explanation of terms**
* **SD card:** A small, removable memory card that is used to store data, such as music, photos, and videos.
* **eMMC:** A type of embedded flash storage that is used in many mobile devices.
* **Flash:** The process of writing data to a non-volatile memory device, such as an SD card or eMMC.
* **Boot:** The process of starting a computer and loading the operating system.
**analogy**
Installing an operating system on a DragonBoard 410c using a Linux host is like baking a cake. You need to prepare the ingredients (the microSD card and the operating system image), mix them together (unzip the operating system image to the microSD card), and then bake the cake (flash the operating system image to the DragonBoard 410c). Once the cake is baked, you can enjoy it (use the newly installed operating system on the DragonBoard 410c).
**challenge**
Come up with a creative way to use a DragonBoard 410c with a Linux host. For example, you could use a DragonBoard 410c and a Linux host to create a smart home device, a robot, or a self-driving car.
This section show how to install an operating system to your DragonBoard™ 410c using the SD Card method on a Linux host computer. ***
- Step 1: Prepare MicroSD card
- Step 2: Find SD Card Device name
- Step 3: Recall Download Location
- Step 4: Unzip SD Card Install Image
- Step 5: Go to directory with SD Card Install Image folder using Terminal
- Step 6: Locate SD Card Install Image
- Step 7: Install Image onto SD Card
- Step 8: Prepare DragonBoard 410c with SD card
- Step 9: Install image onto DragonBoard 410c
Step 1: Prepare MicroSD card
- Ensure data from microSD card is backed up
- Everything on microSD card will be lost by the end of this procedure.
Step 2: Find SD Card Device name
- Use host computer
- Open “Terminal” application
- Remove SD card from host computer and run the following command:
$ lsblk
Note all recognized disk names Insert SD card and run the following command (again):$ lsblk- 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 from Downloads page.
- This file will be needed for the next step.
Step 4: Unzip SD Card Install Image
- When unzipped, you will have a folder with the following contents:
- Install Image (.img)
- license.txt
Step 5: Go to directory with SD Card Install Image folder using Terminal
- Use host computer
- Open “Terminal” application
-
cd to the directory with your unzipped SD Card Install Image
$ cd <extraction directory>
#Example:
#<extraction directory> = /home/YourUserName/Downloads
#For this example we assume the "SD Card Install Image" is in the Downloads folder.
$ cd /home/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 listed 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 of 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
- db410c_sd_install_Y.img
- This
.img file is what will be flashed to your SD Card.
Step 7: Install 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 oflag=sync status=noxfer
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 with out the partition. - 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
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!
