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.
On demand.
Custom Board Support, OS Integration
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
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 across all platforms — HAB/AHAB (NXP i.MX), OP-TEE/TrustZone (ARM), UEFI Secure Boot (x86/Intel)
- 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
“We needed BSP bring-up on a new NXP i.MX95 platform in 6 weeks. L4B delivered in 10 days — kernel, drivers, secure boot, the full stack. Our engineering team could focus on the application from week 2.”

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.
- 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.
