LABCSMART delivers specialized embedded Linux and Linux kernel engineering services, from initial silicon bring-up to production-ready BSPs. With over 11 years of industrial experience and active upstream kernel contributions, LABCSMART provides the kind of technical depth that shortens your development cycles and reduces risk on critical embedded projects.
All developments are carried out remotely, with the possibility of on-site interventions throughout France and internationally for expertise and consulting missions.
Engineering Services
Linux Kernel & Device Driver Development
Development and bring-up of Linux device drivers across a wide range of subsystems: PCIe host controllers, audio (ASoC/rsnd), Ethernet (stmmac/GBETH), thermal (TSU), DMA controllers (rz-dmac, ICU), clock and reset frameworks (CPG). Patches submitted and maintained in the upstream Linux kernel.
BSP Development & System Integration
Full Board Support Package development using Yocto Project and Buildroot. Custom layer creation, kernel configuration, rootfs design, SDK generation, and CIP kernel backporting for industrial and automotive platforms requiring long-term support.
Boot Chain & Secure Boot
U-Boot and SPL porting and bring-up, TF-A and OP-TEE integration, FIT image construction and signing, secure boot chain implementation, and trusted execution environment setup. RAUC OTA update system integration with A/B partition strategies and cryptographic bundle signing.
RTOS & Bare Metal
Zephyr RTOS application and driver development, FreeRTOS integration, STM32 bare-metal peripheral driver design with libopencm3, custom bootloader development, and MCU power management optimization.
Cybersecurity
Threat analysis and risk assessment, secure boot and trusted execution environments, encryption and authentication implementation, Trusted Platform Module (TPM) integration, secure element management with PKCS#11, and secure OTA update mechanisms.
Performance & Debugging
Boot time optimization, power management tuning (CPUFreq, CPUIdle, runtime PM, GENPD), real-time latency analysis, kernel tracing and profiling, and systematic debugging of complex driver and subsystem interactions.
How We Work
LABCSMART engagements typically follow one of three models depending on your project stage and internal capabilities:
- Technical consulting — short-term expert engagement to unblock a specific problem, review architecture decisions, or audit an existing BSP or driver implementation.
- Development mission — end-to-end driver or BSP development, from specification through testing and upstreaming, with full documentation and knowledge transfer.
- Embedded in your team — longer-term involvement working alongside your engineers, covering specific subsystems or platforms while your team retains full ownership.
All work is carried out from our premises. On-site missions in France and internationally are possible for consulting and expertise engagements. To discuss your project, get in touch.
Upstream Linux Kernel Contributions
LABCSMART maintains an active upstream contribution record across multiple Linux kernel subsystems, primarily for Renesas SoC platforms. Recent accepted and in-review work includes:
- PCIe — host controller drivers for RZ/G3S and RZ/G3E, including inbound window alignment, ASPM L1 suspend/resume fixes, MSI restoration, and internal DMA controller support
- Audio (ASoC) — rcar_sound driver extensions for RZ/G3E and RZ/V2H, DMA ACK signal routing via ICU, clock management (ADG, SCU), and suspend/resume handling
- Thermal — RZ/G3E TSU thermal driver with PM runtime and trip point handling
- Ethernet — GBETH/stmmac improvements including TX checksum offload and physical port identification
- DMA — rz-dmac and ICU fixes for cyclic transfer reliability and ACK signal routing
- Clock/Reset — rzv2h-cpg clk_hw API migration and PCIe clock initialization macros
Trusted by Industry Leaders
LABCSMART has delivered engineering services to companies including Renesas, Faurecia/Forvia, Continental, EDF, Baylibre, Valeo, Elektrobit, Leica Geosystems, Carestream Dental, Qorvo, and Faiveley — across automotive, industrial, IoT, and defense sectors.
