First met the DragonBoard 410c development board

The DragonBoard 410c is a development board with Qualcomm® SnapdragonTM 410 (64-bit quad-core processor). It is fully functional and powerful, with built-in 8GB eMMC (supports standard microSD card slot) and built-in wifi. Bluetooth, and GPS module with HDMI output and USB interface (3). All of this is integrated into a board that is only credit-sized and priced at just $75.

How to burn Android and Ubuntu systems

There are two ways to write, one is to write the system through the SD card, and the other is to burn through the fastboot.

Write by SD card 1. Download SD card image and extract

Download the Ubuntu SD card image from here

Download the Android SD card image from here

2. Write image to SD card

View the SD device by the following command:

Sudo fdisk -l

Then execute the dd command to write the image to the SD card:

Sudo dd if=db410c_sd_install_YYY.img of=/dev/XXX bs=4M

Finally, be sure to execute the following command to ensure that the data is written:

Sudo sync

3. Adjust the development board S6 switch to the 0-1- 1-0 position

The S6 switch is switched to the state shown below. The white switch is 1 (on) and the bottom is 0 (off).

4. Insert the SD into the development board slot and power up

Connect the display device via HDMI, connect the mouse and keyboard, and power on.

5. Install the system into the development board eMMC

After power-on, the following installation interface will appear. Click Install. After a few minutes, you will be prompted to install the pop-up window. Do not click ok to restart the system.

6. Exit the SD card and set the S6 switch to the 0-0-0-0 position

S6 is set as shown below:

7. Restart the system

Then click the ok button in the interface dialog to restart the system after burning.

Burning through fastboot

In addition to using the SD card to burn the system, we have a more convenient and quick way, which is to burn the system through fastboot.

Install the Linaro/Ubuntu system

1. Download Ubuntu system bootloader

Download Ubuntu bootloader image from here

2.DragonBoard 410c boots to fastboot mode

First you need to make sure that S6 is in the 0-0-0-0 state and then you need to connect to the PC via usb. There are two ways to enter fastboot, one is to enter through the sudo adb reboot bootloader command, and the other is to press and hold the S4 (volume-) button during startup.

3. Burn the bootloader

Unzip the downloaded bootloader, then go to the unzipped directory and execute the following command to burn the bootloader:

Sudo ./flashall

Because the bootloader part includes the partition information, you must restart it after burning the bootloader:

Sudo fastboot reboot bootloader

4. Download the boot image and root image of the Ubuntu system.

Download the Ubuntu boot image from here

Download the Ubuntu root image from here

5. Burn the boot and root images

After the downloaded image is decompressed, it is programmed by the fastboot command:

Sudo fastboot flash boot boot-linaro-vivid-qcom-snapdragon-arm64-BUILD#.img

Sudo fastboot flash rootfs linaro-vivid-developer-qcom-snapdragon-arm64-BUILD#.img

6. Restart the system

Sudo fastboot reboot

Install Android system 1. Burn bootloader image

As with the first three steps of Ubuntu, start up to fastboot mode and execute sudo ./flashall.

Download Android bootloader image from here

2. Download the Android image

Download the boot image from here

Download the system image from here

Download the userdata image from here

Download the recovery image from here

Download the persist image from here

Download the cache image from here

3. Burn Android image

After extracting the downloaded image file, execute the following command to burn:

Sudo fastboot flash boot boot.img

Sudo fastboot flash system system.img

Sudo fastboot flash userdata userdata.img

Sudo fastboot flash recovery recovery.img

Sudo fastboot flash persistence.img

Sudo fastboot flash cache cache.img

4. Restart the system

Sudo fastboot reboot
