Embedded Linux

Our Experiences with Embedded Linux

• Hardware/Project specific configuration for Yocto build system
  e.g.
  - define specific Yocto layer and priority's
  - define own Yocto distribution
  - definition of images for flash file system
  - definition of recipes for own developed software components
  - configuration of recipes with bbappend files
• Configuration of U-Boot and Linux kernel for specific Hardware
• Backport of Drivers and Kernel Features
  e.g. for Linux Wifi driver
• Project specific application development
  e.g.:
  - Audio Video Bridging (AVB) avb taker, avb listener and avb control applications in C and C++
  - network manager in python for network decices and services like Wifi, LTE Modem, dhcl, dns, firewall
  - UDS Application e.g. for diagnostic services , Fault manager and update procedures
• Security relevant measures
  Secure Boot Process, AppArmor (Mandatory Access Control), Firewall, Secure update procedures, CVE checks
• Integration of third party software components
  e.g.:
  - VPN solution
  - captive portal solution
• Verification
  Static code analysis, Unit-, Integration- and System tests
