High-Performance Embedded Linux & Real-Time Engineering Solutions
From custom Linux BSP architectures and low-level driver development to PREEMPT_RT deterministic optimization—we build reliable, production-ready systems for industrial, defense, medical, and connected hardware platforms.
Powering Industrial-Grade Embedded Linux Systems
Deploying embedded Linux distributions requires balancing tight boot times, hardware constraints, deterministic latency, and long-term security maintenance. At Real Time Group, we provide complete engineering solutions tailored to your hardware architecture.
Whether executing complex board bring-up on new silicon, setting up robust toolchains for cross-compilation, optimizing Linux for hard real-time execution, or building a reproducible Yocto build pipeline, our senior engineering teams take full ownership of your critical software work packages.
Core Embedded Linux Engineering Capabilities
Building dependable Linux-based edge hardware demands expertise across every layer of the operating system stack. Our specialized engineering team provides end-to-end technical support:
Custom Linux BSP Development & Build Systems (Yocto & Buildroot)
We design, build, and maintain lightweight embedded Linux distributions using the Yocto Project and Buildroot. We configure tailored root filesystems, initialize hardware during initial board bring-up, and integrate a reliable bootloader (U-Boot) alongside customized hardware abstraction layers stripped of unnecessary overhead.
Cross-Compilation Toolchains & Driver Development
Our engineers set up optimized cross-compilation environments and author custom kernel modules and device drivers for proprietary peripherals, sensors, FPGA bridges, PCIe, CANbus, and high-speed communication interfaces. We perform kernel tuning within the Linux BSP to achieve ultra-fast boot times (sub-second cold boots) and minimal memory footprints.
Bootloader (U-Boot) Optimization & Board Bring-Up
During low-level board bring-up, we adapt and fine-tune the bootloader (U-Boot) to support custom memory layouts, power management configurations, and custom hardware initialization sequence requirements before handing control over to the kernel.
Hard Real-Time Linux with PREEMPT_RT
When your application demands strict timing determinism without switching to a traditional RTOS, we apply and configure the PREEMPT_RT patch set within your embedded Linux distributions. We optimize interrupt handlers, task scheduling priorities, and memory locking to guarantee predictable low-latency response times across all target boards.
Secure Boot Chains & Over-The-Air (OTA) Updates
We leverage the bootloader (U-Boot) and secure boot flows (using HAB, High Assurance Boot, and TPM integration) to prevent unauthorized code execution. We integrate reliable fail-safe A/B dual-partition Over-The-Air (OTA) update frameworks (such as RAUC or Mender) directly into our Yocto layer pipelines to ensure seamless remote firmware maintenance without risk of bricking devices in the field.
Embedded Linux System Security & Hardening
Protecting connected edge hardware requires proactive hardening across the entire Linux BSP. We implement SELinux/AppArmor security policies, encrypted storage volumes (dm-crypt/LUKS), disable unneeded debug ports, and establish automated vulnerability scanning pipelines to ensure long-term compliance.
