Empowering Embedded Systems with Secure, Real-Time, and Customized Linux

L4B Software delivers robust, secure, and real-time embedded Linux solutions tailored for high-performance and safety-critical applications. With over 20 years of experience in Linux kernel development, BSP integration, open-source security, and industry certification support, we are a trusted technology partner to leading OEMs across medical, automotive, industrial, and consumer markets.

Custom Board Support, Kernel Integration & Mainlining

We provide comprehensive Linux bring-up and board support tailored to your hardware:

  • BSP development and low-level hardware initialization
  • Bootloader customization (e.g., U-Boot) and secure boot enablement
  • Linux kernel porting, optimization, and hardening
  • Custom driver development, integration, and validation
  • Support for Yocto, Buildroot, Debian, and custom Linux distributions
  • Mainline kernel integration and upstreaming services to future-proof your product and reduce long-term maintenance effort

Middleware, HAL, and Custom APIs

We bridge the gap between custom hardware and application logic:

  • Hardware Abstraction Layer (HAL) development
  • Custom APIs for device interaction via standard Linux interfaces
  • Human Interface Device (HID) integration and input system tuning
  • Full SDKs and wrappers for scalable software development
  • Migration from legacy operating systems to Linux with codebase continuity

Real-Time Linux Integration

For applications requiring strict determinism and low-latency response:

  • Integration of PREEMPT_RT or real-time frameworks into Linux kernel
  • Real-time scheduling, IRQ tuning, and process prioritization
  • RT driver development with user-space control APIs
  • Coexistence with standard Linux multitasking and services
  • Suitable for robotics, automotive, industrial automation, and medical use cases

Embedded Security and System Hardening

Security is designed into the system architecture—not added later:

  • Secure Boot, trusted firmware chains, and key storage
  • Kernel hardening, SELinux, and AppArmor policies
  • Encrypted communication, secure storage, and access controls
  • CVE scanning, vulnerability patching, and runtime protection
  • Aligned with ISO 27001, ISO 21434, IEC 61508, and industry cybersecurity frameworks

Industry-Specific Linux Platforms

L4B Software delivers tailored Linux distributions optimized for domain-specific compliance and performance:

  • MediTUX OS™: A secure Linux platform for medical OEMs, aligned with FDA, NIST, and IEC 62304 requirements
  • Automotive & Mobility: ISO 26262-ready Linux stacks for infotainment, ADAS, and telematics systems
  • Industrial & IoT: Hardened Linux for automation gateways, edge controllers, and safety systems
  • Embedded Vision & AI: Linux platforms tuned for edge inference, camera interfaces, and hardware accelerators

Full Lifecycle Support and Certification Readiness

We support the full software lifecycle—from development through to field maintenance:

  • Agile or V-model-based development processes
  • Certification-ready documentation, including FMEA, SBOM, FTA, and test artifacts
  • OTA-ready secure update frameworks
  • Support for ISO 13485, ISO 26262, IEC 62304, ASPICE, and more
  • Long-term support plans and maintenance contracts for multi-year deployments

Why a Maintenance Contract Is Critical for Embedded Linux Systems

Linux is a dynamic and evolving open-source ecosystem—not a static product. Any commercially deployed Linux-based system requires continuous monitoring, updating, and validation to remain secure, functional, and compliant.

A structured maintenance contract is essential to:

  • Ensure security: New vulnerabilities (CVEs) emerge daily. Without monitoring and patching, your system becomes exposed.
  • Manage open-source dependencies: Kernel APIs, libraries, and drivers frequently change. Unmanaged updates can break compatibility or introduce regressions.
  • Meet regulatory requirements: Standards such as ISO 13485, IEC 62443, or ISO 27001 mandate vulnerability management and patch traceability.
  • Protect long product lifecycles: Industrial, medical, and automotive systems may be deployed for 10+ years. Continuous support ensures longevity.
  • Enable secure updates: L4B’s OTA-ready infrastructure allows you to safely deploy kernel, application, and firmware updates in the field.

Our maintenance services include:

  • Security patch integration and validation
  • Kernel and driver updates
  • CVE monitoring and mitigation
  • SBOM versioning and documentation
  • Integration with secure OTA mechanisms
  • Lifecycle support aligned with certification requirements
  • Support for keeping your system aligned with mainline Linux developments to reduce technical debt over time

What Makes L4B Software Unique

L4B Software is more than a software vendor—we are a strategic partner trusted by OEMs around the world to build and maintain their Linux platforms in regulated and performance-critical industries.

Cross-Industry Domain Expertise

We support OEMs across medical, automotive, industrial, and consumer markets, giving us the versatility to design Linux systems aligned with sector-specific needs and certifications.

In-House, End-to-End Engineering

We control the full development lifecycle—kernel, middleware, security, OTA, and maintenance. No outsourcing. No shortcuts. This ensures consistency, IP protection, and full vertical integration.

Security and Compliance Built from the Start

Our platforms are designed for compliance from the ground up, including secure boot, kernel hardening, SBOM generation, CVE mitigation, and secure update mechanisms.

Long-Term Maintenance and Lifecycle Support

Unlike integrators that deliver and exit, we offer lifecycle contracts that ensure your product remains secure, functional, and certifiable—through launch and beyond.

Tailored Distributions, Not One-Size-Fits-All

We deliver Linux solutions custom-built for your exact hardware, real-time needs, certification requirements, and use case—whether for medical devices, vehicle ECUs, or AI-based edge platforms.

Linux Mainlining Expertise

We support mainlining of your custom drivers and SoC support to the official Linux kernel, reducing future integration efforts, technical debt, and maintenance costs. Our team ensures code alignment with community standards and upstream acceptance.

Global Presence with Local Support

With teams in Europe, North America, and Asia, we provide global coverage with on-site capabilities and customer-aligned development models.
