Я работаю с STM32F030RC MCU и хочу сохранить данные во внутреннем EEPROM: STM32F0 не имеет раздела EEPROM, поэтому я использовал эмулированный EEPROM для хранения данных во флэш-памяти.Иногда во время чтения или записи произошла ошибка в обработчике данных процессора.

Чтобы получить полное представление о проблеме, это функция записи, и я посмотрел на флэш-память во время перезаписи: все записанные мной данные были успешно сохранены во флэш-памяти.
