Hello, I’ve read Atlantis OTA update system spec and I’m confident I can deliver a production-grade, safe, rollback-capable OTA path that works with the STM32H723VIT6 and the unmodified ESP32 NCP for Blynk. I will implement a protected boot stub in flash, a robust STM32 Update Service that writes only to the inactive slot, and a clear OTA metadata protocol that the boot stub can enforce for confirm/rollback. The ESP32 NCP remains a transport path, while the STM32 components handle all flash operations, CRC checks, and signature hooks. I will provide a complete boot-stub package, a standalone Update Service module compatible with Arduino-style code, and a Blynk OTA streaming spec. For testing, I’ll ship Wi‑Fi-based test firmware that validates the entire OTA lifecycle, including normal operation, power-loss resilience, resume after interruption, and rollback. I’ll also deliver a concrete test plan and example test builds that clearly show slot, build, and status. Next steps: confirm environment constraints (toolchain version, memory layout, and any required certifications), then I’ll deliver the initial boot-stub and update service within 2 weeks and start parallel Wi‑Fi OTA validation. 1) Do you have a fixed toolchain version for the STM32CubeMX/IDE setup and any required IDE plugins? 2) What is the target flash layout (sector sizes, protection strategy, and option bytes) you expect for the 0x08000000 boot stub region? 3) Any specific allowed cryptographic methods for metadat

Hello, As an experienced electronic hardware and firmware engineer, I can help you design and develop a state-of-the-art OTA Dual-Bank STM32 Update System for your Atlantis controllers. My knowledge stretches from PCB design to firmware development and RF analysis, giving me the ability to approach your project from multiple angles. With your project's non-negotiable constraints in mind, I'll ensure the dealer toolkit flawlessly toggles BOOT0 + RESET and that flashing occurs without interfering with the running firmware or writing metadata. My core competency in firmware development makes me a natural fit for this project. I've mastered programming microcontrollers like STM32 and ESP32 so I'm comfortable managing communication protocols vital for our OTA system's success - UART, SPI, Ethernet, USB, CAN, and MODBUS. My expertise’s in WiFi is particularly relevant here because I’ll be developing test firmware that validates the entire OTA lifecycle over Wi-Fi before Blynk integration. During my career, I have consistently transformed ideas into successful products using meticulous design and development techniques. I am no stranger to working on projects with tight deadlines and high stakes such as yours. Not only will my solutions be cost-effective, but they will also provide consistent high-quality performance. I am excited about the prospect of contributing to your project and would love to discuss further how I can be of service. Thanks!

@julianm260

Hello, I’m an embedded systems engineer with 7+ years of experience building production-grade firmware for STM32 platforms, including 5 OTA-enabled devices deployed with rollback and power-loss protection. I’ve implemented dual-bank (A/B) boot architectures on STM32H7-class MCUs with protected boot stubs, strict metadata-driven state machines, and raw-binary flashing compatibility. For your Atlantis system, I would deliver a minimal, deterministic boot stub (<8 KB) at 0x08000000, fully write-protected via option bytes, handling slot selection, trial/confirm/rollback, and metadata validation exactly as specified. I’ve built OTA metadata systems with CRC32 and monotonic build numbers, validated against mid-write power loss, interrupted downloads, and failed-confirm scenarios. On the application side, I’ve developed Arduino-compatible STM32 update services that correctly manage H7 flash erase/program granularity, stream firmware safely into the inactive bank, and confirm within a controlled first-boot window. You’ll receive all required deliverables—boot stub package, update service module, multiple test firmware builds (A/B, auto-confirm, delayed, fail-to-confirm), and a comprehensive test plan covering 10+ failure cases. I’m comfortable validating dealer force-flash → OTA recovery flows and enforcing “latest fw_build wins” behavior, and I can lock down the flash layout and metadata schema within 2–3 days to de-risk the rest of the implementation.

@andriik18

Hi, I am excited about the opportunity to implement the OTA firmware update system for the Atlantis controllers. With my expertise in embedded systems and over 7 years of experience, I am well-equipped to ensure a robust and power-loss tolerant solution that meets your specific requirements. My skills in developing firmware for STM32 combined with a deep understanding of OTA processes will help streamline the integration with Blynk. I have successfully completed projects involving bootloaders and state management, which aligns perfectly with your need for safe, rollback-capable firmware handling. I suggest we start the initial phase ASAP, allowing sufficient time for rigorous testing and validation of each OTA lifecycle step before full integration. Best regards, Andrii

@yaroslavmark

✅Okay, I got what you want exactly. I am a senior embedded firmware engineer with over 10 years of experience, providing STM32 (H7 series), secure bootloaders, dual-bank OTA systems, ESP32 transport layers, and production-safe firmware update architectures. In my opinion, the right way to approach this project is to keep the boot stub extremely deterministic and safety-focused while pushing all complexity into a well-structured Update Service. I would design the A/B logic, metadata lifecycle, and rollback rules so they are fully power-loss tolerant and compatible with your non-negotiable dealer flashing workflow. This project is very similar to my previous works. I’ve implemented dual-bank OTA systems on STM32H743 and STM32F767 where the boot stub occupied the first 32–64 KB, used option-byte write protection, and enforced trial/confirm rollbacks with CRC validation. In one project, I handled OTA images up to ~1.2 MB, implemented resume-after-power-loss using chunk offsets, and validated firmware using CRC32 plus optional SHA-256 hooks. ✅ So, I will divide your project like following: ⚡ Define flash layout, boot stub responsibilities, linker scripts, and option-byte protection ⚡ Implement STM32 Update Service with safe erase/write, CRC verification, and metadata commits ⚡ Deliver Wi-Fi OTA test firmware (Slot A/B builds) with clear trial/confirm/rollback signaling ⚡ Produce Blynk NCP OTA streaming spec and a complete validation test plan Best regards.

Hi there! OTA updates on STM32 can easily fail if rollback and power loss safety are not handled right. A weak boot flow or wrong metadata logic can brick devices and break trust. I am an embedded developer with strong experience in STM32, Arduino runtime, and OTA systems. I have built dual-bank firmware update systems with safe rollback and CRC validation. I have worked with ESP32 as a transport layer and STM32H7 flash, option bytes, and boot protection. My approach will be strict and production focused. I will design a minimal protected boot stub with clear A/B slot rules and rollback logic. I will build an update service that writes only to the inactive slot with full verification. I will deliver WiFi test firmware to validate the full OTA lifecycle before Blynk use. All code, layout, and documentation will be clean and easy to review. check our work https://www.freelancer.com/u/ayesha86664 Do you already have a preferred flash layout, or should I propose one based on STM32H723 best practices? Let me know if you’re interested & we can discuss it. Best Regards Ayesha
