Engineers’ painful lessons: 80% of device bricking incidents stem from Bootloader design flaws! Introduction In the late-night production workshop, my colleague Wang stared blankly at the 200 devices that had just failed an upgrade—A single erroneous OTA upgrade directly caused an entire batch of devices to become bricked. This painful experience is not uncommon in … Read more
1. Implementation Concept of OTA Based on On-Chip Flash OTA (Over-The-Air) essentially allows devices to receive new firmware during operation and write it to on-chip Flash, ultimately replacing the old firmware. There are two key points to implement OTA: 1. Receive new firmware; 2. Write the new firmware to Flash. On the STM32F103C8T6 chip, the … Read more

Introduction: As the functions of smart vehicles become increasingly complex, the vehicle software also needs to be continuously updated to fix vulnerabilities, optimize performance, and add new features. If there is a problem during the update process, such as a sudden power outage or network interruption halfway through the upgrade, the vehicle’s functions may become … Read more
We were working on a smart streetlight control system, deploying over 100,000 terminals nationwide, with the core being the STM32F429. The system periodically receives OTA firmware updates via a 4G network, automatically rebooting after the upgrade, completely unnoticed by the users. The initial OTA tests went smoothly, and everyone gradually got used to the automatic … Read more
Source | Chip Home In today’s rapidly evolving IoT devices and the increasing demand for remote maintenance, OTA (Over-the-Air) remote upgrade technology has become an indispensable part of smart hardware development. OTA upgrades refer to the process of sending new firmware to devices via wireless communication methods (such as Wi-Fi, Bluetooth, NB-IoT, etc.) to achieve … Read more
