Обновить таблицы разделов загрузки ⇐ C++

[Anonymous]

Я работаю над патчем, предназначенным для обновления таблиц раздела зашифрованного устройства ESP32, используя USB -соединение для процесса обновления. Во время тестирования я столкнулся с постоянной проблемой, когда устройство входит в цикл загрузки после применения патча. Это предотвращает успешное завершение обновления и временно не поддается употреблению устройства. Я ищу рекомендации о том, как диагностировать и решить эту проблему цикла загрузки, чтобы убедиться, что обновление таблицы разделов может быть применено правильно, а устройство может нормально загружаться впоследствии. Пожалуйста, найдите код ниже: < /p>
