Safe and Secure Embedded Linux OS
A Perfect Balance of Creative Innovation & Reliable Engineering Design for Embedded Linux OS
Secure and Safe Embedded Linux is one of our core specialization. We support Linux for embedded systems since 2004 continuously, contribute to the Linux source code and thereby help to increase its popularity in the business sector. Our comprehensive experience allows us to deliver optimized Operating Systems that support custom boards and proprietary hardware. The entire development life-cycle is done in-house with transparent project management and customer involvement. We have proven experience in a wide range of industries, including automotive, industrial automation and custom solutions for consumer electronics.
Board Support Packages
Due to our knowledge and hands-on experience we create BSP fitting distinct hardware to each project, proprietary hardware support, board bring-up or special communication protocols. L4B also creates a custom API for existing hardware as well as develops custom bootloaders (u-boot), kernel enhancements, integrate off-the-shelf drivers and develop device drivers for custom boards and custom Embedded Linux. Furthermore we support various standard file systems and build environments like Buildroot, Yocto, and many more. L4B have earned a reputation for providing high-quality solutions for projects with very complex requirements and unique demands.
Yocto Support
Our solutions support various hardware and software Architectures with Yocto’s recipes, builds, scripts and customization which allow our OEM and Tier-1 in customers to build and provide stable, traceable and secure Linux aligning with the community mainline feathers and BSP.
Linux Mainlining
Since Linux is an Open-Source project, we can offer a mainlining service. This offers the ability to feedback your custom solutions to Linux and removing any constraints your product has to a specific Linux distribution. If you wish to protect your proprietary intellectual property, this can be avoided.
Middleware Development
We are specialize in development of middle-ware software to wrap low level functionality for your hardware:
- Custom APIs – creating a set of commands for your hardware operating under the regular Linux interface.
- HAL: Hardware Abstraction Layer, creating software solutions for your hardware to connect seamlessly to the normal Linux interface. For instance: a custom Human Interface Device inserted into the Linux code in such a way that the Linux upper-level fully supports the device.
- Keeping your code conventions and functions transparent to the application layer when migrating to Linux from a different architecture or OS
- SDKs and wrappers: we supply a software development kit fully featured and well documented for future development of software products
- Development Tools and IDE integration.
Real-Time Linux
RT Linux is a special patch under the normal Linux system that transforms an OS into a Real-Time OS. This mode of operation allows control over real-time operations.
The RT capability provides process timing management, priority management and external peripherals timing while maintaining the normal Linux system tasks and services. This feature greatly extends the abilities of Linux regarding embedded systems. It´s opening a wide range of options for specialized embedded hardware needs.
We have the knowledge and experience to offer you custom made drivers with extensive API’s custom built to your requirements. L4B works with the hardware timing constraints while revealing an API for the user space that allows full control to the user and all the other features that the Linux system can offer.
