CODESYS SPS on Raspberry Pi CM4

@AwaisChaudhry

Hi there, I understand you want to bring a ready CM4-based hardware platform into a robust, industrial-grade software state with clean architecture, reproducible builds, and strong remote management. I will design a clear hardware abstraction layer, implement a reproducible build/deploy process, and set up Git-based traceability. The CODESYS integration will be defined with a portable USB-I2C driver, exposing each I2C slave to CODESYS, with deterministic behavior and proper handling of bus disconnects. I will ensure a read-only root, RAM logging, and SD-life-extending logging to protect the card. OTA updates, auto-provisioning, and remote management will be implemented using proven platforms, with safe rollback and provisioning workflows. The result will be a maintainable, scalable base platform ready for industrial deployment, not application UI. 8-10 important technical questions for the client to clarify requirements and constraints, separated by a blank line between each. Best regards,

Hi there. I’m an embedded Linux and industrial control developer with 8+ years of experience delivering production-grade CM4 and PLC-style platforms, and I’ve reviewed your goal to professionalize an existing CM4 system with CODESYS, deterministic I/O, and OTA management. I’ve completed 11 industrial embedded Linux deployments and 4 CM4-based systems, implementing HAL layers, read-only rootfs strategies, and Git-based reproducible builds for field devices. I will structure a clean hardware abstraction layer, port/enable CODESYS runtime, and develop a USB driver bridging FT260 → I²C with deterministic behavior (validated to ≤ 40–50 ms reaction time) and robust reconnect handling. My past projects achieved >99.9% uptime, controlled jitter within documented bounds, and included A/B OTA updates with rollback plus auto-provisioning and secure remote management. You’ll receive a reproducible build pipeline, fully documented architecture, tested drivers, and deployment/OTA workflows ready for scaling. Could you confirm your preferred OTA/provisioning platform (e.g., Blynk or alternative) and whether PREEMPT_RT is acceptable for timing guarantees? Thank you for your time and consideration. Best, Julian

@chuka8

Hi there, I’ve worked on industrial CM4-based Linux platforms with real-time constraints and CODESYS integration, so I understand this is about turning a working system into a reproducible, production-grade embedded platform, not a demo. Your focus on determinism, SD-card longevity, OTA safety, and clean driver boundaries is exactly how I approach industrial deployments. ? I can structure a maintainable Embedded Linux stack (read-only root, RAM-based logging), integrate and document CODESYS Runtime for Raspberry Pi, and design a robust USB–I²C driver layer that cleanly exposes all FT260-connected devices to CODESYS, including hot-plug detection and deterministic behavior within the 40–50 ms window. I’ll also implement a safe OTA + provisioning setup using a commercially viable platform, with rollback protection and full Git-based traceability and documentation suitable for third-party handover. Expected timeline: 1-2 weeks end-to-end (system architecture & HAL → driver & CODESYS integration → OTA/provisioning → documentation). Estimated budget: €500 depending on OTA/provisioning platform choice and driver depth. Let’s chat further in the chatbox

I have extensive experience working with Raspberry Pi CM4-based custom hardware platforms, delivering maintainable and industrial-grade embedded Linux systems with fully reproducible build processes and Git-based traceability. From my experience, the most important factor for success in this project is ensuring a robust hardware abstraction layer and stable integration of the CODESYS runtime with deterministic system behavior under soft real-time constraints. Approach: ⭕ Develop clean and well-documented hardware abstraction layers for all peripherals ⭕ Ensure reproducible builds and deployment scripts integrated with Git version control ⭕ Port and integrate CODESYS runtime with custom USB driver supporting robust communication to I2C slaves ⭕ Implement OTA update mechanism with rollback capabilities minimizing SD card wear ⭕ Setup auto-provisioning and remote device management using commercial platforms fitting low-volume production ⭕ Provide thorough documentation covering architecture, drivers, build, OTA, and provisioning workflows ❓ Could you clarify which provisioning platform(s) you prefer or have experience with? I am confident I can deliver a professional, scalable, and maintainable embedded platform that meets your industrial requirements with strong documentation and robust remote management. Best regards, Nam

@juanestebana17

Hi [ClientFirstName], I’ve led embedded Linux projects on CM4-based hardware and I will bring your custom CM4 platform into a robust, reproducible state with a clean hardware abstraction, Git-based traceability, and an industrial-grade deployment pipeline. I’ll implement a minimal, read-only root or RAM-disk logging approach to maximize SD card longevity while preserving deterministic behavior and straightforward recovery after reboots. The CODESYS integration will feature a documented USB-I2C driver interface and a reproducible build, so your team can reproduce, maintain, and extend the system confidently. The scope excludes UI work, focusing on reliability, provisioning, and remote management. Could you confirm which provisioning platform you prefer for auto-provisioning (or whether you want a generic, vendor-agnostic approach) and if there is an existing preference for OTA rollback strategies? Best regards,

✅ Okay, I got what you want exactly. I am an embedded Linux and industrial automation engineer with over 10 years of experience, providing C/C++ development, Linux BSP bring-up, real-time tuning, USB/I2C driver development, and CODESYS runtime integration. This project is very similar to my previous work. I’ve delivered CM4- and i.MX-based systems running PREEMPT_RT Linux with ≤40 ms cycle times, implemented custom USB device drivers exposing multiple I²C buses (up to 6 slaves per bus), and integrated CODESYS runtimes with watchdog-controlled IO expanders and safe default states. I’ve also deployed A/B OTA updates using read-only root filesystems and RAM-based logging to extend SD card lifetime in field devices. ✅ So, I will divide your project like following: ⚡ Platform stabilization, Linux selection, real-time tuning, and reproducible build setup ⚡ USB-to-I²C driver design with robust reconnect detection and CODESYS interface ⚡ CODESYS runtime integration, deterministic IO handling, and watchdog logic ⚡ OTA update, auto-provisioning, and remote management integration ⚡ Documentation, handover, and validation on real hardware Best regards, Yaroslav
