Добрый день стоит задача удалить все данные контроллера и сбросить его к заводским настройкам.
Batch No 6.6.0D 409
Firmware version 202002171718
HW Revision 6.6.0
Пробовали сбрасывать по инструкциям через usb с заливкой прошивки на флешку и переименованием ее в соответствии с инструкцией. Но при перезапуске контроллера не происходит индикации в соответствии с инструкцией и прошивка не устанавливается. (ни кроткое нажатие ни длинное не помогло, флешки пробовали разных производителей.)
Попробуйте подключить Debug консоль, покажите что выводит при старте контроллера с воткнутой флешкой в первый USB порт, с образом wb6_update_FACTORYRESET.fit на борту.
Должно быть примерно так:

Файловая система не понравилась. Попробуйте заново отформатировать флешку в систему FAT32, на пример программой Rufus.
“Делаем” флешку из образа - он точно работает…
образ
скачиваем, потом с помощью
Программа
записываем на флешку.
Скачали образ, записали через программу, пока нет изменений.

Другую флешку пробовали?
А к контроллеру еще что-то подключено?
USB разъем используете ближний к сетевым?
Замечательно. А флешка которая не работала - не USB3 случайно? Собираю статистику.
Не грузилось с Trancend USB2.0 4GB
Загрузилось только после записи имиджа с Samsung USB 3.1 32 GB
Обе флешки до этого форматировали и загружали свежий образ https://github.com/wirenboard/wirenboard/releases
с переименованием по инструкции, результата не было.
Благодарю.
