Tosil

Comprehensive Embedded Linux
Services We Offer

We provide end-to-end Embedded Linux engineering that spans from low-level bootloader bring-up to full-stack application deployment. Our services are tailored to support custom hardware platforms, including ARM, x86, and RISC-V architectures.

Bootloader Customization & Boot Time Optimization

U-Boot customization, board diagnostic framework, environment scripts
Secure boot (FIT images, verified boot, signed binaries)
Boot time optimization using static linking, deferred init, and initramfs trimming
Quick boot on constrained platforms

BSP Development for Custom Hardware

BSP creation on ARM, RISC‑V, x86, and FPGA SoCs
Custom board porting from scratch — DDR init, Pinmux Configuration, PMIC bring-up, flash partitioning
Yocto/Buildroot/Debian-based BSP stacks with reproducible builds
Device tree authoring, device probing, udev rules, and firmware loading

Linux Kernel Porting & Real-Time Tuning

Full port of mainline or vendor kernels to new SoCs and carrier boards
RT patches (PREEMPT_RT) and low-latency scheduling
Dynamic debug, tracepoints, ftrace, perf, and scheduler instrumentation
Driver Integration, Enhancement & Customization for varied peripheral devices

Device Driver Development

Kernel and user-space drivers for peripherals: camera (V4L2), audio (ALSA), graphics (DRM/KMS), touchscreen, modems, Wi-Fi/BT
DMA, power states, async I/O, interrupt handling
Upstream-compliant driver development and mainlining strategies
Fast boot on constrained platforms

Build System Development

HAL/BSP Design & Update for real-time OS integration We develop and maintain scalable, modular Linux build systems using Yocto, PetaLinux, Buildroot, Make, and CMake, ensuring your development is reproducible and maintainable.
- Layered architecture in Yocto
- Custom recipes and Bitbake classes
- Package management and dependency resolution
- SDK generation for application teams

Embedded Application Development

Full-stack development in Qt, GTK, C++, or Python for device control & UX
IPC design (DBus, MQTT, gRPC) and integration with middleware stacks
Support for HMI touch interfaces, camera UIs, OTA interfaces, and web-based dashboards
Performance benchmarking, multithreading, and crash recovery strategies
