We are pleased to announce a new Honister Boot2Qt Qt6 Release! The release uses the latest Qt 6.3.0 release. Below you will find the download links for the images and toolchains as well as detailed instructions for the build. You can view a demo of the image running on our Nitrogen8M Plus SOM here.

Prebuilt Images

You can download the Boot2Qt Yocto images from here:

You can download the Boot2Qt Linux toolchains from here:

You can download the Boot2Qt Windows toolchains from here:

Instructions on how to use the QBSP toolchain in your Qt application development can be found here. As usual, you'll need to register on our site and agree to the EULA because it contains NXP content.

How to Flash

You can program the SW to eMMC using the instructions below: programming-emmc-on-i-mx-platforms You can also program the SW to SD Card or USB Stick via zcat and dd under Linux: 

~$ zcat *boundary-image*.wic.gz | sudo dd of=/dev/sdX bs=1M

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

Build procedure

This image uses the 6.3 branch of the meta-boot2qt repo, which uses Qt version 6.3.0. This image uses the honister branch of our boundary-bsp-platform repository. To build the image, we recommend using a Docker Container so that you can build with a reproducible and stable build environment. Otherwise, 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 initialize the environment. 

~$ mkdir ~/b2qt6_hardknott && cd b2qt6_hardknott
~/b2qt6_hardknott$ repo init -u https://github.com/boundarydevices/boundary-bsp-platform -b honister -m b2qt.xml
~/b2qt6_hardknott$ repo sync

Then, setup the environment for building. For this image we will be building the b2qt distro for the target machine

~/hardknott$ MACHINE= DISTRO=b2qt . setup-environment build

Finally, build the Boundary Boot2Qt Embedded Qt6 Image and Linux Toolchain (boundary-b2qt-embedded-qt6-image and meta-toolchain-b2qt-embedded-qt6-sdk). This can be done building the boundary-meta-b2qt-embedded-qbsp. 

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

Note: You can just build the Qt6 image by running "bitbake boundary-b2qt-embedded-qt6-image". To build a toolchain for Windows platforms add the following line to local.conf: 

SDKMACHINE = "x86_64-mingw32"

If you are interested in each project revision at the time of the build for the prebuilt images, you can find a frozen manifest for those images here. The image file will deploy to tmp/deploy/images/{MACHINE}/b2qt-embedded-qt6-image-{MACHINE}.wic.gz. The Linux toolchain will deploy to tmp/deploy/qbsp/meta-b2qt-embedded-qbsp-x86_64-{MACHINE}-6.3.0.qbsp. The Windows toolchain will deploy to tmp/deploy/sdk/b2qt-x86_64-mingw32-meta-toolchain-b2qt-embedded-qt6-sdk-{MACHINE}.qbsp.

Demo examples

We can run demos using the toolchain with qt creator. Below are a few examples of Qt6.3 demo applications running on our Nitrogen8M Plus. Coffee Machine Demo
