We are pleased to announce release an Boot2Qt embedded qt5 image and toolchain using Yocto 2.7, Warrior.

Below you will find the download link for the image as well as detailed instructions for the build.

For the Impatient

You can download the Boot2Qt Yocto images from here:

You can download the Boot2Qt Linux Toolchains from here (refer below for instructions on building the Windows toolchain):

As usual, you'll need to register on our site and agree to the EULA because it contains NXP content.

How to Burn

You can to program this image either using U-Boot USB Mass Storage Gadget or program the image onto an SD Card.

Instructions on programming the SW can be found below:

U-Boot USB Mass Storage Gadget

For i-mx6 and i-mx7:

programming-emmc-on-i-mx6

For i-mx8

programming-emmc-on-i-mx8

SD Card, USB Stick

You can flash the image onto an SD card or USB Stick using dd under Linux:

~$ sudo dd if=*boundary-image*.wic of=/dev/sdX bs=1M && sync

In addition, you can use the etcher utility to flash the SD Card or USB stick via Windows or Linux:

Build procedure

This image uses the warrior branch of the meta-boot2qt repo, which uses Qt version 5.14.0.

To build the image, you’ll need these packages installed as well as this repo tool that can be installed like this:

~$ sudo apt-get install repo

Then create your build directory and clone the meta-boot2qt repo

~$ mkdir ~/b2qt && cd b2qt
~/b2qt$ git clone git://code.qt.io/yocto/meta-boot2qt.git -b warrior

Next, run the b2qt-init-build-env script for your device. In this case we will use nitrogen8m 

~/b2qt$ ./meta-boot2qt/b2qt-init-build-env init --device nitrogen8m

Then, export that device to the MACHINE variable

~/b2qt$ export MACHINE=nitrogen8m

Source the setup-environment script.

~/b2qt$ . ./setup-environment.sh

Finally, build the Boot2Qt Embedded Qt5 Image and Linux Toolchain ("boundary-b2qt-embedded-qt5-image" and "boundary-meta-toolchain-b2qt-embedded-qt5-sdk")

~/b2qt$ bitbake boundary-meta-b2qt-embedded-qbsp

Note: You can just build the Qt5 image by running "bitbake boundary-b2qt-embedded-qt5-image"

 

To build a toolchain for Windows platforms add the following line to local.conf:

SDKMACHINE = "i686-mingw32"

 

After some time this should build the same image as above.

The image file will deploy to tmp/deploy/images/{MACHINE}/b2qt-embedded-qt5-image-{MACHINE}.wic.

The Linux toolchain will deploy to tmp/deploy/qbsp/meta-b2qt-embedded-qbsp-x86_64-{MACHINE}-5.14.0.qbsp.

The Windows toolchain will deploy to tmp/deploy/sdk/b2qt-i686-mingw32-meta-toolchain-b2qt-embedded-qt5-sdk-{MACHINE}.7z.

 

Display support

Please make sure your platform includes the latest U-Boot for i.MX8M:

This version of U-Boot supports the display configuration, allowing to use any of the following displays:

Note that we've noticed that the NXP HDMI driver is picky when it comes to custom display timings (sometimes refuses to set the clock).

So if you are experiencing any issue with HDMI, please try entering the following commands in U-Boot in order to force the use of standard timings:

=> setenv cmd_custom 'setenv bootargs $bootargs drm_kms_helper.edid_firmware=HDMI-A-1:edid/1280x720.bin'
=> saveenv
