Здравствуйте.
Ситуация страшная, с полиции принесли регистратор запороленый. через UART поставил не то смещение теперь в живых остался только загрузчик. Мучаюсь 3 недели.
Регистратор Vidstar vsr-1650 16ch 960h
Процессор Hi3521
АЦП 2 шт Intersil TW2968
SPI winbond w25q128bvfg
На плате hi3521_tw2968_v30
Ищу дамп.
Очень прошу помощи.

Что стирали? Что стёрлось? Как интерфейс выглядел раньше?

Я написал sf erase 0x100000 0xf00000, перепутав размер со смещением. Xm прошивки не встают(некоторые встают, но не определяет сетевую карту), run up не выполняется. Даже не посмотрел как выглядело меню.
