Embedded Linux

Projects – Ready to Use

Customer's challenges

For complex embedded tasks, especially when networking or graphical user interfaces have to be implemented, a complete operating system is required. If no hard real time requirements exist, this is often Linux, particularly for IoT (Internet of Things) applications.. The development of the software, but also the hardware of such a system is significantly more elaborate than a microcontroller based system.

Outcome

The software delivery encompassed the boot loader and the BSP (Board Support Package), in many cases with additional drivers in the kernel or in user space. The BSP has been put into operation together with the hardware and so tested and debugged together with it. According to the customer wishes we developed the application: networking, business logic and user interfaces.

Implementation

We have successfully conducted several projects in this embedded Linux realm, on platforms like PowerPC (PowerQUICC), MIPS and particularly ARM. In some projects, the hardware was already there, in others we have developed the processor system and the peripherals. Depending on the production volume, as a complete system or based on a COM (Computer On Module)/ SOM (System On Module), for the later only the baseboard with supply, interfaces and sensors had to be designed by us.
