Industrial Longevity Open-Source Operating Systems.
Prevas has the largest Scandinavian independent Industrial Linux team within design, development, customization, and longevity maintenance of industrial grade embedded Linux Board Support Packages (BSP) – including varieties of Linux like Android and uClinux. These services are handled by a core team within Industrial Linux together with a number of Linux competences spread throughout Prevas.
Prevas’ professional services within Industrial Linux cover all aspects of professional BSP work.
Prevas ensures that all development can be executed efficiently and with professional longevity maintenance as a quality target for the BSP. Starting with the early specification and technical decisions needed to enable a high quality BSP. Continuing with Quick Start BSP’s for fast tracking of early hands-on testing and evaluation, including education seminars for in-house development.
Development is finalized with delivery of a fully customized Industrial Linux (pure Linux, Android or uClinux) BSP, including an application software development kit, customized kernel, bootloader, rootfs, and deployment integration.
After delivery, Prevas continues to take responsibility for the delivered BSP and the cyber security aspects of it. Prevas has developed a longevity maintenance program for industrial grade BSP’s, ensuring continuous upgrades, cyber security intelligence and enhancements of the BSP, sustaining the value of the BSP.
When the customer product approaches end of life, Prevas helps to enhance the re-use of BSP work to ease the development of new software platforms in the future – even after 15-20 years of usage.
For embedded industrial use, there is a constant demand for stability, security and reproducibility in software development, often with an urge for stability at the same time. In order to provide this for industrial Linux based products, Prevas used and contributors to the Yocto Project community.
Yocto is an integration tool for Industrial grade Linux Board Support Packages (BSP’s), born from a demand for stability and longevity maintenance of customized Linux. Since its early beginnings in 2010, Yocto has been used for Linux BSP integration and maintenance for many different solutions, from sensor systems to life science devices, and has shown high-value for many customers.
The main idea is to keep a stable customized Linux for +10 years for customer specific hardware (HW), regardless that the HW may change over the product lifetime (e.g. different HW versions or CPUs). With Yocto, Prevas’ customers keep the same Linux API, kernel version etc. in a given BSP version, even when running on different types of HW. This solution efficiently lowers the application development and maintenance cost. Suddenly the customized Linux API becomes the actual platform for application development and not the raw HW, allowing the application developers to focus on value adding application features instead of working on low level HW support.
Prevas’ view on the Industrial Linux Lifecycle is shown below:
Yocto based BSP’s are made by Prevas ranging from small uCLinux MMU-less CPU to multi-core x86 or ARM based boards with small or large memory available and with or without display and touch.
Prevas’ Industrial Linux Team provides professional development and support on Android for Industrial systems, covering the full aspect of the system:
Prevas has a long history as a professional industrial Linux provider. Prevas provides partners and customers with great value, with support on every aspect of embedded Linux:
An off-the-shelf embedded Linux platform for Industrial use on customized board, with support for full customization and longevity maintenance. Prevas Industrial Linux is provided with the Yocto Project integration tools for an efficient and professional embedded Linux platform and application work flow.
Prevas Industrial Linux for a customized board can be executed in three steps over time or used as is:
Basic – The standardized Prevas Industrial Linux platform with no customization. Get your custom board supported in Prevas Industrial Linux, fast time-to-market and full Linux BSP tests for a hardened embedded Linux solution (incl. performance, stability and functionality test execution).
Plus – Added customizations on kernel, bootloader and rootfs. Enhance your Prevas Industrial Linux Basic platform with additional kernel drivers, bootloader optimization and rootfs additions, with easy maintenance through the Prevas Industrial Linux release flow.
Custom – Full customization and specialized release flow Break out of the Prevas Industrial Linux release flow and handle everything specially, as a regular custom Yocto project.
