Linux Host
This section show how to install a new operating system to your Qualcomm Robotics RB2 development kit using the fastboot method on a Linux host computer.
- Step 1: Make sure fastboot is set up on host computer
- Step 2: Connect host computer to RB2
- Step 3: Boot RB2 into fastboot mode
- Step 4: Recall location of all downloaded files
- Step 5: Unzip all files
- Step 6: Flash all files to the RB2
- Step 7: Reboot RB2
Step 1: Make sure fastboot is set up on host computer.
You can install fastboot from source or using your distro package manager.
-
- 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.

-
# Red Hat flavour (Fedora, CentOS) $ sudo yum install android-tools # Debian (ubuntu) $ sudo apt-get install fastboot
Step 2: Connect host computer to RB2
- RB2 must be powered off (unplugged from power)
- please check the Quick start guide to set the dip switches on the development kit
Step 3: Boot RB2 into fastboot mode
Please read all bullet points before attempting
- Disconnect the power cable from the board and make sure no USB cable is plugged into the board
- Hold down the “VOL-“ button while reconnecting the power supply.
- Tap the “ON/OFF” button while continuing to hold the “VOL-“ button for ~5 seconds after the green LED lights up.
- Release “VOL-“ button
- Connect the USB3 Type C between the Linux PC and the board
- 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
$ sudo fastboot devices
Typically it will show as below
de82318 fastboot
Step 4: Recall location of all downloaded files
Recall location of all downloaded files from the downloads page:
boot
and rootfs
downloaded from the downloads page
Linaro/Debian: Recall location of - You should have downloaded the
boot
file - You should have downloaded the
rootfs
file
Step 5: Unzip required files
For Debian
$ gunzip boot-linaro-sid-arm64-qcom_qrb4210-rb2-*.img.gz
$ gunzip linaro-sid-developer-arm64-*.img.gz
Step 6: Flash all images to the RB2
- Use host computer
- Use “Terminal” application
- Recall location of extracted(unzipped) files
-
cd
to the directory with your unzipped files - From within extraction directory, execute the following commands:
Linaro/Debian:
# (Once again) Check to make sure fastboot device connected
$ sudo fastboot devices
# It will show similar to below if the device is connected successfully
de82318 fastboot
# cd to the directory the boot image and were extracted
$ cd <extraction directory>
# Make sure you have properly unzipped the boot and rootfs downloads
$ sudo fastboot flash boot boot-linaro-sid-arm64-qcom_qrb4210-rb2-**BUILD#**.img
$ sudo fastboot flash userdata linaro-sid-developer-arm64-**BUILD#**.img
Note: Replace BUILD# in the above commands with the file-specific date/build stamp.
Step 7: Reboot RB2
- Unplug power to RB2
- Ensure HDMI connection to a monitor
- Plug power back into RB2
- Wait for board to boot up
- Board will boot into command line
Note: For Linaro/Debian the username and password are both “linaro” when the login information is requested.
Congratulations! You are now booting your newly installed OS directly from eMMC on the RB2!
