Привет всем! Есть девайс на STM32, обновление прошивки происходит с SD карты. Обновляется бинарником, сгенерированными ИАРом. Как в бинарник включить в начало какое-нибудь слово (или дату компиляции прошивки), которое было-бы для моего девайса уникальным?
спасибо
Я устанавливаю все нужные константы после таблицы векторов:
