Webinar recording: How to set PICO-PI-IMX8M for Qt app

TechNexion not only introduced a great feature - Boot to Qt (B2qt) support for PICO-IMX8 modules but also answered many of our questions about embedded devices. Watch our video with the manufacturer to learn more.

Boot to Qt

Boot to Qt (b2qt) is the reference distro used in Qt for Device Creation. It combines Poky (a reference distribution of the Yocto Project), meta-qt5 and various BSP meta-layers. It provides an integrated solution for building toolchains (the set of tools that compiles source code into executables that can run on your target device and includes a compiler, a linker, and run-time libraries) and b2qt images with the latest Qt version for different devices.

B2qt source code with TechNexion BSP meta layers will be published on the public TechNexion GitHub soon. In the meantime, you can use private TechNexion GitHub or download binary demo images from the TechNexion FTP server. Qt enables both commercial and open source licensing. TechNexion b2qt images use an open-source Qt license.

Certification of TechNexion modules based on i.MX8M processor is in the progress, they should appear on the Reference Target Devices. TechNexion is also working on b2qt for modules based on i.MX6 processors.

PICO-IMX8 modules vs. Raspberry Pi

The participants of the webinar were interested in comparing the PICO-IMX8 modules with Raspberry Pi. As Henri mentioned, it is difficult to compare them because the products are intended for another market. Raspberry Pi is a great single board computer designed for the hobby market while PICO-IMX8 modules are designed for the industrial market.

During the webinar, we went through many interesting topics with Tomasz Swatowski and Henri Parmentier from Technexion and we got answers to our questions. Check it out:
