Case Study — Embedded Development

Driver development in user space & kernel space across Windows, macOS, Linux, Android, and RTOS — from board bring-up to production.

overview

We build reliable device drivers and platform software that bridge silicon, peripherals, and applications. Our teams cover board bring-up, BSP/bootloader work, kernel modules, user-space drivers, Android HALs, and RTOS firmware — with an emphasis on robustness, performance, and maintainability.

Operating systems

Windows • macOS • Linux • Android • RTOS (FreeRTOS, Zephyr)

Driver domains

Sensors • USB • PCIe • networking • storage • camera • audio • power/thermal

Highlights
  • User-space & kernel-space drivers
  • BSP & bootloaders (U-Boot, fastboot)
  • Android HAL/AIDL integrations
  • macOS IOKit / DriverKit
  • Windows WDF (KMDF/UMDF)
  • Secure boot & firmware update

capabilities

Kernel drivers

Linux kernel modules (kbuild, DT), Windows KMDF, macOS IOKit/DriverKit; interrupts, DMA, power states.

User-space drivers

LibUSB/WinUSB, ioctls, Udev rules, sandboxed services, cross-platform SDKs.

Android HAL

AIDL/HIDL, Binder, vendor services, CTS/VTS readiness, SELinux policies.

RTOS & bare-metal

FreeRTOS/Zephyr drivers, ISR/DMA, low-power modes, secure boot, OTA.

Buses & peripherals

I²C, SPI, UART, USB, PCIe, MIPI CSI/DSI, GPIO/PWM, ADC/DAC, CAN, Ethernet.

Security

Secure boot, code-signing, TrustZone, sandboxing, SELinux/AppArmor, update pipelines.

delivery

1) Discovery & bring-up

Schematics review, boot flow, device tree, clocks & power, debug ports (JTAG/SWD).

2) Driver development

Kernel or user-space path selection, IO, DMA, PM, error handling, tracing.

3) Validation & integration

Unit & HIL tests, profiling, conformance suites (WHQL/CTS/VTS), packaging and CI.

We ship with debug tooling (trace, logs), recovery paths, and documentation to support long-term maintenance.

case snapshots

Cross-platform USB camera

Linux V4L2 kernel driver + Android HAL with power saving and hot-plug robustness; user-space SDK for apps.

Result: Stable streaming, lower CPU, CTS/VTS compliant.

PCIe accelerator

Windows KMDF + Linux kernel module with high-throughput DMA, MSI-X, and IOCTL APIs.

Result: Unified API, WHQL ready, 0-copy data path.

RTOS sensor hub

Zephyr-based drivers (I²C/SPI), low-power modes, over-the-air updates; Linux user-space lib for host.

Result: Weeks-long battery life, deterministic latency.
