Raspberry Pi
You need a production image for CM4, CM5, Pi 4, or Pi 5. Stock Raspberry Pi OS is not it. We build and own the full software stack — BSP, Yocto, kernel, bootloader, RTOS, OTA — on your carrier board, handed off to you.
- Yocto BSP for CM4, CM5, Pi 4, Pi 5. Pico companion firmware on RP2040 / RP2350.
- Replaces stock Raspberry Pi OS with a minimal, reproducible Yocto build.
- Custom BSP and device tree for your carrier board — not the IO board.
- Signed boot chain on CM4 / CM5. A/B OTA via tryboot or RAUC.
- You own the full source, build system, and documentation. No lock-in.
Board Bring-Up and BSP
We work directly with your hardware engineering team. Schematic and PCB review before fab, custom BSP development, then methodical board bring-up covering boot, memory, and every peripheral on your board.
- Schematic and PCB review — power sequencing, DDR layout, boot straps, high-speed lanes.
- Custom BSP and device tree for your carrier — every interface mapped to your hardware.
- Boot verification — EEPROM config, boot-order policy, signed boot on CM4 / CM5.
- Memory validation — eMMC, NVMe, SD bring-up and stress test.
- Peripheral bring-up — CSI/DSI cameras, CAN, RS-485, USB, I2C, SPI, industrial I/O.
Yocto and Embedded Linux
Stock Raspberry Pi OS is built for general use. Your product needs a minimal, reproducible, locked-down image you can rebuild, audit, and maintain for the life of the product. That is what Yocto gives you — and what we deliver.
- Reproducible Yocto build on meta-raspberrypi — same inputs, same image, every time.
- Replaces stock Raspberry Pi OS — no unneeded packages, no default credentials, no stray services.
- Read-only rootfs, hardened system services, minimal attack surface.
- Full source, recipes, and build system handed over — you own it, no lock-in.
- SBOM generation — know exactly what is in your image and where it came from.
Bootloader and Boot Optimization
A failed update or corrupted image never bricks the device. We configure the full boot chain for your storage and boot policy, implement a golden recovery image, and tune boot time for your application requirements.
- EEPROM bootloader config, tryboot A/B mechanism, U-Boot option per project.
- Golden boot image in a protected partition — survives a bad update or corrupted storage.
- Automatic rollback on failed boot or failed health check.
- Storage partitioning: eMMC on CM4, NVMe on CM5 / Pi 5, redundant OS slots.
- Boot time optimization — trimmed init, deferred services, fast-boot for kiosk and HMI targets.
Linux Kernel & Device Drivers
We customize the kernel for your hardware — not the generic Raspberry Pi config. Driver development for your specific peripherals, config minimization for faster boot and smaller attack surface, and PREEMPT_RT for control applications.
- Kernel config minimization — remove what your product does not use.
- PREEMPT_RT builds for bounded, deterministic latency on control applications.
- Camera drivers — libcamera, Unicam, CSI pipelines for your specific sensors.
- Display drivers — DSI and DPI panels.
- CAN, I2C, SPI, GPIO, PWM, RS-485 — drivers for your exact peripheral set.
RTOS and Microcontroller
The Raspberry Pi cannot do hard real-time. The Pico can. We split the system by criticality — Linux on the Pi for networking, UI, and compute; FreeRTOS or Zephyr on the Pico for deterministic I/O and control loops.
- FreeRTOS and Zephyr firmware on RP2040 / RP2350 (Pico / Pico W).
- PIO (Programmable I/O) for custom protocols and precise timing without CPU involvement.
- UART, SPI, and USB communication links between Pi and Pico with structured protocols.
- RTOS drivers for sensors, encoders, PWM, and safety-critical I/O on the Pico.
- Watchdog and health supervision from the real-time domain.
Middleware
We integrate the middleware stack your application needs — communication protocols, cloud connectivity, and industry-specific stacks — built into the Yocto image and validated on your hardware.
- MQTT and cloud agents — AWS IoT, Azure IoT, fleet telemetry.
- Modbus, OPC UA, RS-485 for industrial gateway and machine integration.
- ROS 2 builds tuned for Pi 5 for robotics applications.
- Wayland kiosk, Qt, LVGL, Chromium for HMI and display applications.
- Read-only rootfs, watchdog, hardened system services across all variants.
OTA and Fleet Management
You need to update devices in the field without bricking them or sending a truck. We implement A/B OTA with a golden recovery image, automatic rollback, and staged rollouts — so a bad update never stops a device permanently.
- A/B updates via tryboot or RAUC — two OS slots, automatic switchback on failure.
- Golden recovery image in a protected partition — survives a bad A and a bad B.
- Signed updates chained to the CM4 / CM5 secure boot chain.
- Staged rollouts — push to 1% of the fleet, validate, then the rest.
- Delta updates — ship only changed bytes, critical for metered or slow connections.
SDK, Debugging and Profiling
Your application team needs to build, debug, and profile on the target without touching Yocto. We deliver a cross-toolchain, sysroot, and full eSDK — everything needed to develop on the platform from day one.
- Evaluation image for Pi 4 / 5 and CM4 / CM5 IO boards — running before your carrier exists.
- Application SDK — cross-toolchain and sysroot for your app team's x86 machines.
- Yocto eSDK — full build system handed to your platform team to modify and rebuild.
- Remote debugging — gdbserver, perf, ftrace, boot analysis.
- CI/CD integration with hardware-in-the-loop smoke tests on real hardware.
