- Boot to Qt based on Yocto
About Boot to Qt
Boot to Qt is a light-weight, Qt-optimized, full software stack for embedded Linux systems that is installed into the actual target device.
The stack can be customized to production with Build-Your-Own-Stack tooling, including proprietary Yocto Project recipes.
The full B2Qt documentation is available at Qt for Device Creation official page.
Requirements
You should be familiar with the Yocto tools and the concept of recipes. For more information, see Yocto Project documentation.
To get started, you need the following:
- Install the dependencies for the Yocto tools. In Ubuntu, the following packages are required:
$ sudo apt-get install gawk curl git-core diffstat unzip p7zip gcc-multilib g++-multilib \ build-essential chrpath libsdl1.2-dev xterm gperf bison texinfo rename
$ which git-lfs > /dev/null || sudo apt-get install git-lfs || \ (curl -s https://packagecloud.io/install/repositories/github/git-lfs/script.deb.sh | sudo bash && sudo apt-get install git-lfs)
Setting Up Yocto Build Environment
Run the setup script that initializes the Yocto environment.
$ mkdir -p ~/var-b2qt/sources/ $ cd ~/var-b2qt/sources/ $ git clone -b $ cd .. $ ./sources/meta-variscite-boot2qt/b2qt-init-build-env init --device
b2qt-init-build-env has the following additional command line options:
- list-devices: show all supported devices that can be used for a Boot to Qt build
- mirror: create a local mirror of the yocto repositories. This enables you to use the same repository downloads for multiple build environments, when initializing with init --reference <mirror path>.
For all command line options, see:
$ ./sources/meta-variscite-boot2qt/b2qt-init-build-env help
Building the Image and Toolchain
After the Yocto environment is set up, you need to configure the build environment for your target device:
$ MACHINE= source ./setup-environment.sh
Yocto recipes for Boot to Qt for embedded Linux have two main targets to build: The target image, and the external toolchain that can be used with Qt Creator for building Qt applications.
$ MACHINE= bitbake b2qt-embedded-qt5-image $ MACHINE= bitbake meta-toolchain-b2qt-embedded-qt5-sdk
The target rootfs image is located at:
~/var-b2qt/build-/tmp/deploy/images//b2qt-embedded-qt5-image-.img
and the new toolchain installation file is:
~/var-b2qt/build-/tmp/deploy/sdk/b2qt-x86_64-meta-toolchain-b2qt-embedded-qt5-sdk-.sh
Create a bootable SD card
SD card structure
This is the structure of our Recovery/Extended SD card:
The SD card is divided into 3 sections as shown in the picture above:
- The first unallocated 4MiB are saved space for U-Boot. It can be replaced using the dd command as described in the Yocto Build U-Boot section.
- The first partition is a fat16 partition used for the device tree files and the kernel image file. You can copy them as described in the Yocto Build Linux section.
- The second partition is an ext4 partition that contains the complete root filesystem (including the kernel modules).
Note:
The last unallocated area is not used. It is there so that the rootfs will fit on any 4GB SD card, as not all 4GB SD cards are really the same size. If you want, you can use a program such as GParted to resize the roofs partition and make it end at the end of your specific SD card (of course, you can also use SD cards with much bigger capacity than 4GB, and then it makes more sense to resize the partition).
Also, if you create the extended SD card yourself by following the Create an extended SD card section below, and you use the '-a' option, the rootfs partition will end at the end of your specific SD card automatically.
B2Qt pre-built bootable SD card
The B2Qt build products contains a complete image to be flashed directly to an SD card.
Example usage:
$ sudo umount /dev/sdX* $ sudo dd if=tmp/deploy/images//b2qt-embedded-qt5-image-. of=/dev/sdX bs=1M && sync
Replace sdX with the right device name. This can be obtained by "dmesg" command on your host Linux PC, after the SD card reader is inserted.
- Note: Booting your system from an SD card requires pressing the boot-select button, or switching the relevant DIP switch to "Boot from SD card", according to the relevant start-up guide of your system
Drawbacks of the native . b2qt-built image, (relative to the Recovery/Extended SD card):
- The rootfs partition doesn't use the entire SD card.
- The rootfs partition is not labeled as rootfs.
- The NAND flash and eMMC installation scripts and images are not included.
Creating an extended SD card
Variscite provides the var-create-yocto-sdcard.sh script which creates our NAND/eMMC recovery SD card. The script copies the NAND/eMMC flash burning scripts and relevant binaries for your convenience.
Later, you will be able to follow Boot2QT Recovery SD card guide to burn your images to NAND flash or eMMC.
Note:
This is essentially the same as our pre-built Recovery SD image, with the following main differences:
- The pre-built image's rootfs partition size is 3700MiB, which is also the default size when using the script, but the script also has an option to set the rootfs partition size to fill the whole free space of the used SD card. Anyway, you can always resize the partition later with an external tool such as gparted.
Naturally, the pre-built image is more straight forward and easier to use, while the script method is easier to customize.
Usage:
- Follow the Setup and build Yocto guide, and bitbake b2qt-embedded-qt5-image.
- Plug-in the SD card to your Linux HOST PC, run dmesg and see which device is added (i.e. /dev/sdX or /dev/mmcblkX)
$ cd ~/var-b2qt $ sudo MACHINE= sources/meta-variscite-fslc/scripts/var_mk_yocto_sdcard/var-create-yocto-sdcard.sh /dev/sdX Replace /dev/sdX with your actual device name, e.g. /dev/sdb
Create an extended SD card image using a loop device
It is also possible to use the var-create-yocto-sdcard.sh script to create an extended SD card image, while using a loop device instead of attaching a real SD card.
$ cd ~/var-b2qt
Create an empty file using the following command:
$ dd if=/dev/zero of=-extended-sd.img bs=1M count=3720
The above command creates a 3720MiB file representing the SD card.
Attach the first available loop device to this file:
$ sudo losetup -Pf -extended-sd.img
To find the actual loop device being used, run:
$ losetup -a | grep -extended-sd.img
Write the content to the loop device to generate the SD card image:
$ sudo MACHINE= sources/meta-variscite-fslc/scripts/var_mk_yocto_sdcard/var-create-yocto-sdcard.sh <options> /dev/loopX
(Replace /dev/loopX with your actual loop device, e.g. /dev/loop0)
Detach the loop device from the file:
$ sudo losetup -d /dev/loopX
To compress the SD card image file use the following command:
$ gzip -9 -extended-sd.img
To write the SD card image to a real SD card device use the following command:
$ zcat -extended-sd.img.gz | sudo dd of=/dev/sdX bs=1M && sync
(Replace /dev/sdX with your actual SD device, e.g. /dev/sdb)
Boot the board with a bootable SD card

Flash from GUI
Touch/Click on the appropriate icon:
- Install Yocto NAND, WiFi: Flash Yocto with WiFi support to NAND flash
- Install Yocto NAND, SD card: Flash Yocto with SD card support to NAND flash
- Install Yocto eMMC (SD/WiFi) : Flash Yocto to eMMC (installs both SD card and WiFi dtbs to the BOOT partition and let U-Boot select between them at boot time)
Setting the Boot Mode
Booting your system from an SD card requires switching the Boot DIP switches. See picture below.
- "00" The current position in the picture will set the system to boot from SD card
- "01" Moving the right switch will set the system to boot from eMMC
- "10" Moving the left switch will set the system to boot from NAND flash
- "11" is illegal.
Be aware that your system has eMMC or NAND but never both.
Booting your system from an SD card requires switching the Boot DIP switches. See picture below.
On the VAR-6ULCustomBoard (with a DART-6UL):
- "00" The current position in the picture will set the system to boot from SD card
- "01" Moving the right switch will set the system to boot from eMMC
- "10" Moving the left switch will set the system to boot from NAND flash
- "11" is illegal.
Be aware that your system has eMMC or NAND but never both.
On the Concerto-Board (with a VAR-SOM-6UL):
- ON-EXT: Boot from the external storage (SD card) - the current position in the picture
- OFF-INT: Boot from the SOM's internal storage (eMMC/NAND flash)
Using only one Ethernet port
Apply the following patch to the Linux kernel source, for removing the second Ethernet port, in case your own custom carrier board only has one and doesn't have the second Ethernet phy:

Notes:
- You can follow the "Build Linux from source code" guide to get the Linux kernel source, apply the above patch, build only the device trees and copy them to your SD card.
- In older kernel releases where there is no imx6ul-imx6ull-var-dart-common.dtsi file, the relevant file to edit is called imx6ul-var-dart.dtsi
To remove the second Ethernet port, in case your own custom carrier board only has one and doesn't have the second Ethernet phy:
Edit the dtsi file of the reference carrier board in the Linux kernel source and remove the &fec1 and &fec2 nodes from it.
In case of the VAR-6ULCustomBoard (DART-6UL carrier), the file is arch/arm/boot/dts/imx6ul-imx6ull-var-dart-6ulcustomboard.dtsi.
In case of the Concerto-Board (VAR-SOM-6UL carrier), the file is arch/arm/boot/dts/imx6ul-imx6ull-var-som-concerto-board.dtsi.
The above will result in using the &fec1 node from the dtsi file of the SOM, as is (as the phy of the first Ethernet port is on the SOM), without adding the second port (which its phy is on the reference carrier board).
Notes:
- You can follow the "Build Linux from source code" guide to get the Linux kernel source, apply the above patch, build only the device trees and copy them to your SD card.

For VCAM-AR0821B (daA3840-mc) and VCAM-AR0521B (daA2500-60mc), a v4l2-compatible video source is also available.
To display the video stream in this mode, run the following commands at the shell prompt:
- 1920x1080@30fps:
# gst-launch-1.0 -v v4l2src device=/dev/video2 ! "video/x-raw,format=YUY2,width=1920,height=1080" ! waylandsink sync=false
- 3840x2160@30fps:
# gst-launch-1.0 -v v4l2src device=/dev/video2 ! "video/x-raw,format=YUY2,width=3840,height=2160" ! waylandsink sync=false

Gestreamer for Kirkstone with NXP support and dual-camera enabled
# gst-launch-1.0 -v v4l2src device=/dev/video2 ! waylandsink
On boards with 2 cameras you can use the 2nd camera by replacing /dev/video2 with /dev/video3 in the above command. Dual camera currently can only work on VAR-DT8MCustomBoard due to hardware limitations of Symphony board.
The following command will simultaneously record two video streams from both cameras:
# gst-launch-1.0 v4l2src device=/dev/video2 num-buffers=100 ! video/x-raw,width=1920,height=1080 ! vpuenc_h264 ! avimux ! filesink location=./test0_h264.avi \
v4l2src device=/dev/video3 num-buffers=100 ! video/x-raw,width=1920,height=1080 ! vpuenc_h264 ! avimux ! filesink location=./test1_h264.avi

Configuring RS485 Half-Duplex
Each UART can be configured for RS485 Half-Duplex mode by using a GPIO pin to drive the receive and transmit enable inputs. This can be configured in the device tree by making the following changes to the uart node and replacing X, Y & Z with the proper values:
&uartX { /* Add RS485 properties to uartX */
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_uartX>, <&pinctrl_uartX_rs485>; /* Add RS485 GPIO pinctrl */
rts-gpios = <&gpioY Z GPIO_ACTIVE_LOW>; /* Add rts-gpios property */
linux,rs485-enabled-at-boot-time; /* Enable RS485 at boot time to skip using TIOCSRS485 ioctl */
status = "okay";
};
Next, configure the RS485 GPIO pin by adding pinctrl_uartX_rs485 to iomuxc. Replace X, GPIO_PIN_FUNCTION, and GPIO_PIN_SETTINGS with the proper values:
&iomuxc {
pinctrl_uartX_rs485: uartXrs485 {
fsl,pins = <
GPIO_PIN_FUNCTION GPIO_PIN_SETTINGS
>;
};
};
Note: For more information about configuring pins, please see i.MX Device Tree Pinmux Settings Guide
After making these changes, RS485 mode will be enabled by default and can be verified from the console by running the commands below. Replace N with the proper value, which is typically X-1 relative to the device tree node uartX:
# stty -F /dev/ttymxcN -echo -onlcr 115200 # echo hello > /dev/ttymxcN
The below logic analyzer capture shows the RS485 RX/TX enable line toggling when writing to the UART:
Please refer to the Linux device tree bindings for more RS485 configuration options.
Expression error: Unexpected > operator. Expression error: Unexpected >= operator. Expression error: Unexpected >= operator. $ cd $ MACHINE= DISTRO=
The above command is only mandatory for the very first build setup: whenever restarting a newer build session (from a different terminal or in a different time), you can skip the full setup and just run
$ cd $ source setup-environment

Automatic device tree selection in U-Boot
As shown in the Build Results table above, we have different kernel device trees, corresponding to our different H/W configurations.
We implemented a script in U-Boot's environment, which sets the fdt_file environment variable based on the detected hardware.
Enable/Disable automatic device tree selection
To enable the automatic device tree selection in U-Boot (already enabled by default):
$ setenv fdt_file undefined $ saveenv
To disable the automatic device tree selection in U-Boot, set the device tree file manually:
$ setenv fdt_file YOUR_DTB_FILE $ saveenv
Useful example: To list all files in the boot partition (where the dtb files are by default) of an SD card:
$ ls mmc 0:1
