Acadia

A custom Yocto-based platform for Compute Module 4 / 5, Pi 4 / 5, and Pico — turning the world's most popular SBC into a real industrial product platform.

• Minimal, reproducible Yocto build replacing stock Raspberry Pi OS for production.
• Validated on Compute Module 4, Compute Module 5, Pi 4, Pi 5; companion firmware on Pico / Pico W.
• Locked-down, updatable, secure, manufacturable — not a hobbyist image.
• Custom BSP and carrier-board bring-up for CM4 / CM5 designs.

Carrier-board bring-up

• CM4 / CM5 carrier board design review with your hardware team.
• Custom BSP: device tree overlays for your carrier — cameras, displays, CAN, RS-485, industrial I/O.
• Board bring-up and smoke test: storage, network, peripheral checkout, I/O validation.
• Bootloader: EEPROM configuration, signed boot enablement, boot-order policy.

Failsafe boot

• Boot-chain customization: EEPROM bootloader config, tryboot A/B mechanism, U-Boot option.
• Golden boot and tryboot-based fallback — recoverable from corrupted storage or failed updates.
• Storage partitioning: eMMC on CM, NVMe on CM5 / Pi 5; failsafe and rollback boot.
• Factory provisioning baked into the first-boot sequence.

Production kernel

• Kernel customization on Raspberry Pi kernel trees; config minimization for boot time.
• PREEMPT_RT builds for control applications.
• Driver development: camera (libcamera / Unicam / CSI), DSI / DPI displays, CAN (MCP2515 / MCP251xFD).
• GPIO / PWM / I²C / SPI integration with deterministic userspace APIs.

Industry-specific images

• rpi-iot — MQTT, cloud agents, fleet telemetry.
• rpi-industrial — Modbus, OPC UA, RS-485 stacks.
• rpi-robotics — ROS 2 builds tuned for Pi 5.
• rpi-kiosk / hmi — Wayland kiosk images, Qt / LVGL / Chromium kiosk modes.
• Hardened system services, read-only rootfs with overlayfs, watchdog.

A/B updates, signed boot

• A/B updates using the native tryboot mechanism or RAUC / Mender.
• Golden recovery image, automatic rollback on failed boot.
• Cloud connectivity, staged rollouts, delta updates, dashboard UI for fleet OTA management.
• Signed updates; signed boot chain on CM4 / CM5.

Build, debug, ship

• Evaluation images for Pi 4 / 5 and CM4 / CM5 IO boards.
• Application SDK and Yocto eSDK for your application teams.
• Debugging and profiling: perf, ftrace, remote gdb, boot analysis.
• CI/CD integration and hardware-in-the-loop smoke tests.

Pico companions

• FreeRTOS and Zephyr firmware on RP2040 / RP2350 (Pico / Pico W).
• Linux for connectivity and UI, Pico for hard real-time I/O — clean separation of concerns.
• PIO (Programmable I/O) development for custom protocols and precise timing.
• UART / SPI / USB communication links with structured protocols.

Prototype to production

• Factory provisioning and per-device identity workflows.
• Manufacturing test suites for the production line.
• Cloud enrollment at first boot, automatically.
• Prototype to production — no replatforming, no rewrite.
