Real-Time Linux Yocto BSP for x86 and iMX6/iMX7/iMX8 CPUs
LinRT Real-Time Linux Yocto BSP for i.MX and x86 are available in 5 deliveries, depending on the latency requirement level expected by the application. LinRT provides Oxygen and Mercury BSPs with PREEMPT-RT to adapt standard Linux kernel API to be determinist or for Cobalt add Xenomai 3 extension to offer RTDM drivers and a POSIX real-time runtime for most demanding applications.
Note: the new LinRT Real-Time Linux Dovetail BSP 4.0 with Linux 5.10 Dovetail Xenomai 4.0 is scheduled for the second half of 2023
Mainline LinRT BSP with DRM/KMS
LinRT Mainline BSP with standard Linux Kernel 5.4 LTS, is based on Yocto Dunfell 3.1 LTS. It is oriented for using DRM/KMS API compatible, not fully compatible with hardware IUP and VPU i.MX features and NXP API library usage. This solution is mandatory for LinRT’s Debian distribution, recommended for dual-head LVDS displays, and for video capture applications with standard Video4Linux Camera sensor support for example.
Demo and Pre-build Images
LinRT proposes demonstration images for each BSP version, with limited features for testing and full development images ready to go with SDK for Phytec Mira i.MX6 SBC, new Phytec Polaris i.MX8M and Polis i.MX8M-Mini SBC SDKs for Pre-built images are provided with platform devicetree sources to give the possibility to rebuild it with your adaptations and own driver’s devicetree driver entries.

Software Development Kit and IDE support
LinRT Yocto SDKs are fully designed for Linux userland and kernel drivers developers, with complete cross-debugging and validation tools solution compatible with eclipse and Qt Creator IDE.
The LinRT SDKs are built by collecting all development packages from Yocto’s recipes used for building the runtime Linux image, to have all necessary headers and libraries for your application development project.
LinRT Network stacks addon
LinRT Real-Time Linux Yocto BSP is designed to addon wire and wireless communication stacks for connected devices and industrial applications. With PREEMPT-RT, LinRT Oxygen, and Mercury BSPs propose low-latency network support for applications. With Xenomai extension and RTDM drivers, LinRT Cobalt BSP provides a real-time Linux solution for field bus as CANopen nodes and Powerlink equipment.
HTML5 Web solution
LinRT HTML5 solution is based on Qt 5.15 LTS QWebEngine Framework, itself based on Chromium version 56 with additional security fixes from newer versions, and openGL ES 2.0 support for i.MX6/i.MX8 Vivante GPUs. LinRT Yocto HTML5 image embeds a Node.JS server with MRRA and UPM libraries with specific platform hardware support, and offers HTTP, REST, and WebSocket compatible APIs for developers.
- NodeJS 8.4
- MRRA and UPM libraries for i.MX6 phyCORE and phyFLEX SOMs
- Qt QWebEngine HTML5 render with GPU WebGL support.
- Full Chromium Web browser for X11 server with Vivante GPU support
Multimedia support
LinRT Yocto BSP provides, full multimedia images, gstreamer with hardware codecs and VPU support, H264 and MPEG4 encoder/decoder. For video capture on i.MX processor, LinRT proposes two solutions, with IPUv3 i.MX capture API, compatible with FSL Community BSP or with IPU and video4linux capture API from mainline Linux Kernel 5.4
Real-Time Linux BSP optimized for i.MX platforms
LinRT Helium, Oxygen, Mercury, and Cobalt Yocto BSPs are based on Yocto Rocko 2.4.4, Yocto Thud 2.6.4, Yocto Dunfell 3.1, and FSL Community BSP in order to provide support for iMX based platforms and include official Linux kernel stable updates backported features and fixes coming from LinRT, vendors, kernel community, and FSL Community itself. It includes support for many IPs such as GPU, VPU, and IPU for NXP i.MX6, i.MX7 and i.MX8 series processors.
Note: for the third quarter of 2023, new LinRT BSPs revision 4.0 will be based on Yocto Kirkstone, Linux 5.10 NXP / Dovetail patch and Xenomai 4.0
Debian Preempt-RT for i.MX platforms
LinRT Debian 11 “Bulleyes” Preempt-RT Distribution is based on LinRT Oxygen Yocto BSP, based on Linux 5.4 PREEMPT-RT kernel with multi-framebuffers using Linux FSLC/NXP i.MX API Compatibility and provides the most efficient IPU and VPU hardware support on Linux. This solution is recommended for applications that require the use of multiple separate-use displays, one as a GUI touch panel and the other for the video screen, for example.
i.MX multi framebuffer support with imx-gpu-vivante galcore driver and openGL ES2.0/3.0 extension.
Note: for 2023 the new LinRT Debian distribution will be based on 11 “Bullseye” image for iMX6Q/DL and iMX8M/M-Mini (with NXP Linux kernel 5.4 PREEMPT_RT BSP)
Multi Framebuffer GUI interface Framework
LinRT Helium, Oxygen, Mercury, and Cobalt Yocto BSPs with multi-framebuffers use Linux FSLC/NXP i.MX API Compatibility and provides the most efficient IPU and VPU hardware support on Linux. This solution is recommended for applications that require the use of multiple separate-use displays, one as a GUI touch panel and the other for the video screen, for example.
i.MX multi framebuffer support with imx-gpu-vivante 6.2.4 galcore driver and openGL ES2.0/3.0 extension.
Note: for 2024, the new LinRT Linux Real-Time Yocto BSP revision will be based on Qt 5.15 LTS and Qt 6.3 (optional) framework
