Arduino Portenta Dual-Core OTA Firmware

@TheElitePro

Hi, I have been doing Embedded programming, solution architecture, IoT product design. I have developed firmware using Real Time Operating System (RTOS) and I have extensive background in working with various microcontrollers. I can develop the OTA with two way authentication i.e. both ThingsBoard server and device will authenticate each other. 1. I have developed OTA for various types of devices and know how to handle intermittent LTE connection. 2. I have complete control on different technologies involved in IoT solution. 3. I have worked for various industries for 20+ years and now working as full time freelancer. So, I am very professional, quality & detail oriented and disciplined in execution. 4. I have developed predictive maintenance solution which has more than 5000 vibration sensors connected on Thingsboard. 5. I am preferred freelancer and have 5 star rating with track record of delivering all the project successfully. All this has resulted into repeat customers. Deliverables 1. I will deliver well documented and optimized code which means it will use RAM and flash efficiently. 2. SHA-256 verified OTA of both internal cores (M7 + M4) 3. README covering build, provisioning, and the exact API calls (HTTP) the device makes to ThingsBoard for pushing status and fetching updates. 4. Test results for the testing done by me 5. Short demo video I can complete the project before the deadline of 15th September. Regards, Vishal

Hello, I understand that you need production-ready firmware for the Arduino Portenta H7 Lite on the Mid Carrier board. My approach will be to create two independent binaries for the M7 and M4 cores, enabling them to communicate with your ThingsBoard instance over HTTP. I will ensure that the firmware supports OTA updates while implementing strict SHA-256 verification for package integrity. For security, I will not only use SHA-256 but also propose using TLS for secure communications and signed manifests for authenticity during updates. The update manager will be designed to handle downloading, validation, flashing, and rollback processes smoothly. Each component will be thoroughly documented to ensure clarity in usage and integration. I will prepare well-commented source code as per your choice of programming environment and provide a comprehensive README, along with a demo video showcasing the dual-core update process. What specific APIs are you currently using on ThingsBoard for integration, and are there any existing libraries or frameworks that you prefer for the Arduino development? Thanks, Muhammad Awais

Hi there, I’d be glad to deliver production-ready firmware for the Portenta H7 Lite with dual-core OTA support to your ThingsBoard instance. My approach will generate independent binaries for M7 and M4, package them in a single update job, and use SHA-256 to validate integrity before flashing. The update manager on-device will track versions, manage flashing for both cores, and provide a safe rollback path if either fails to boot. For security, I’ll extend beyond SHA-256 with TLS-encrypted transport, signed manifests, and strict checksum verification to prevent tampering. ThingsBoard integration will include push status updates and controlled binary pulls over HTTP, with a clear fallback plan for interrupted downloads. Deliverables will include well-commented source code (PlatformIO preferred), a robust update manager, a full README documenting build, provisioning, and API calls, plus a demo video showing end-to-end OTA success. This ensures your fleet is secure, reliable, and field-upgradeable. Best regards, Brian
