Linux Device Driver & BSP Development
We provide low-level Linux engineering services for standard MCU or SoC-based platforms, including kernel customization, device driver development, and system-level optimization.
Kernel Customization, OS Bring-Up & SoC-Level Engineering
Our Linux engineering capabilities span low-level SoC bring-up, kernel architecture customization, and advanced device driver development for ARM-based embedded platforms. We work across bootloader configuration, device tree design, kernel configuration and patching, peripheral driver implementation, and system-level debugging. With strong understanding of Linux internals, memory management, interrupt handling, and hardware abstraction layers, we enable stable, production-ready BSP foundations tailored to custom hardware environments.
