STM32 Universal Boot Loader и стирание секторов памяти

Привет всем! Меня зовут Евгений и я работаю программистом микроконтроллеров в компании Бастион г. Ростов-на-Дону. В своих проектах мы очень часто используем STM32F030 как сопроцессор отвечающий за реалтайм задачи (АЦП, обработка кнопок, управление дисплеем), а вот бизнесс логику выносим на контроллеры помощнее. В процесе работы естественно стал вопрос с выпуске обновлений для устройств и о том как обновлять ПО и нашем "сопроцессоре" (фига себе сопроцессор конечно, но вот такие термины). Так как с основным процессором мы связаны по UART, то сюда как нельзя лучше подошел UniversalBootLoader (UBL), который уже есть во всех процессорах STM. Рассказ о том как прошивать сами контроллеры через UBL уже есть на сайтах многих эмбедеров ( easyelectronics.ru и istarik.ru разжевывали эту тему не раз), но у меня появился отличный сайдквест. Сейчас совсем немного контекста, для понимания с чем я столкнулся. Для стирания памяти через UBL в STM32 есть алгоритм который представлен ниже

#UBL announced that it will deselect an extensive collection of foreign #dissertations & #InternetArchive will be taking over this collection
The dissertations were originally part of an exchange programme between (mostly European) universities until the year 2004 but were never catalogued on arrival. As #Leiden University Libraries has limited space for growth in its stacks, it decided to deselect these dissertations, so that 3.2 km could be freed up for new acquisitions

Among other things, OASIS and its experts are the source of many relevant open #standards, including #UBL (ISO/IEC 19845), the most widely used global e-trade and e-invoicing data model, and the AS4/eDelivery ecommerce data methods embraced by Europe (and other governments) for G2B and G2G interop (the ISO 15000 series).

🌿 What's the relation to #circularity and #greentech? These existing, open-source-driven data methods already are in commerce, use simple tools, and can be extended to securely add as much origin, content, recycyling, and customs metadata as regulations may need. Without any extra wackadoo new tech or proprietary additions.
🤖 Upwardly compatible with more complex methods like #blockchain? Yes. Are parties in commerce REQUIRED to use blockchains, other new untested or proprietary methods, or a math PhD? No. The lesson of 20 years of ecommerce and EDI is clear: simple secure tech is best for large, multi-tier supply chains.
