Linux Host
This section show how to install a new operating system to your Qualcomm Robotics rb5 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 rb5
- Step 3: Boot rb5 into fastboot mode
- Step 4: Flash Bootloader
- Step 5: Recall location of all downloaded files
- Step 6: Unzip all files
- Step 7: Flash all files to the rb5
- Step 8: Reboot rb5
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 rb5
- rb5 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 rb5 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 blue LED lights up.
- Release “VOL-“ button
- Connect the USB3 Type C (5) 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: Flash Bootloader
- Use host computer
- Download Bootloader from the Downloads Page.
- Open “Terminal” application
- Recall location of Bootloader download.
- The bootloader file should be named
qrb5165-bootloader-ufs-Y-XX
- Y represents AOSP or Linux, use either one or the other based on the image you want to use. They both use different GPT.
- XX represents the release number of the Bootloader
-
cd
to the directory with your unzipped Bootloader Folder
$ cd <extraction directory>
#Example:
cd /Users/YourUserName/Downloads
#<extraction directory> = /Users/YourUserName/Downloads
#For this example we assume the "Bootloader" is in the Downloads folder.
$ cd <unzipped Bootloader folder>
#Example:
cd qrb5165-bootloader-ufs-linux-14
#<unzipped Bootloader folder> = qrb5165-bootloader-ufs-linux-14
#This example took place during release 14
# This command will execute the flashall script within the bootloader folder
$ sudo ./flashall
The bootloader has now been flashed to the UFS. Rebooting will launch the newly-flashed boot loader, which will allow us to flash the remaining parts of the operating system.
# Reboot the system so we can flash the rest.
$ sudo fastboot reboot
Step 5: Recall location of all downloaded files
Recall location of all downloaded files from the downloads page, files will be different for Android and Linaro/Debian:
boot
and rootfs
downloaded from the downloads page
Linaro/Debian: Recall location of - You should have downloaded the
boot
file - You should have downloaded ONE of rootfs
file (Either
Developeror
Desktop - ALIP` version)
boot.img.tar.xz
, system.img.tar.xz
, userdata.img.tar.xz
, recovery.img.tar.xz
, persist.img.tar.xz
, cache.img.tar.xz
, downloaded from the downloads page
AOSP: Recall location of - All of these files should have been downloaded from the downloads page
Step 6: Unzip required files
For Debian
$ gunzip boot-*.img.gz
$ gunzip linaro-*.img.gz
For AOSP
$ tar -xvf boot.img.tar.xz
$ tar -xvf system.img.tar.xz
$ tar -xvf userdata.img.tar.xz
$ tar -xvf recovery.img.tar.xz
$ tar -xvf persist.img.tar.xz
$ tar -xvf cache.img.tar.xz
Step 7: Flash all images to the rb5
- 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-buster-qrb5165-**BUILD#**.img
$ sudo fastboot flash rootfs linaro-buster-developer-qrb5165-**BUILD#**.img
Note: Replace BUILD# in the above commands with the file-specific date/build stamp.
AOSP:
# (Once again) Check to make sure fastboot device connected
$ sudo fastboot devices
# It will show similar to bellow if the device is connected successfully
de82318 fastboot
# cd to the directory with extracted images
$ cd <extraction directory>
# Make sure you have properly unzipped the downloads
$ 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 persist persist.img
$ sudo fastboot flash cache cache.img
Step 8: Reboot rb5
- Unplug power to rb5
- Ensure HDMI connection to monitor
- Ensure keyboard and/or mouse connection (Depending on your rootfs selection)
- Plug power back into rb5
- Wait for board to boot up
- Board will boot into either command line or desktop depending on rootfs
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 UFS on the rb5!
