Кучу косяков видно сразу, но самый главный — это то, что splash подгружается ДО полной инициализации CFE, когда можно с клавиатуры нажать Ctrl-C и творить что угодно. В итоге, если splash дохлый или не дай Бог — с JPEG, который сохраняли в прогрессиве, — то все. Финита. У меня один такой уже лежит. Очевидно, только JTAG’ом поднимать. Жесть, одним словом. Кто их учил писать загрузчики — неизвестно.

Консольный лог загрузки D-Link DIB-120: 5 комментариев

  1. Угу, на него. Распиновка там такая же как обычно делают: по краям rx и tx (порядок не помню, но это легко проверить), в центре — питание, между ними — земля.

  2. Привет. Убили eth порт на Dib-120. Сейчас паяем rs232-to-ttl. Есть небольшая проблема в том что нет самого разъема на плате приставки. То есть нужно припаиваться к плате кабелем, если бы был разъем нетрудно было поменять контакты в кабеле при неудаче. Поэтому не подскажешь — на плате Dib120 JP4 имеет 5 выходов, один из них квадратная площадка, остальные круглые. А как понимаю к DB9 разъему на компе должны идти только 4 вывода, Rx,Tx,GND и +5. Не подскажешь распиновку JP4, какой вывод что делает?

  3. Подскажу, но не тут — напиши в аську/скайп/жаббер — есть на странице контактов. А какой вообще прок от DIB-120 без сетевого порта? Проще выкинуть…
    И в любом случае — не надо паять кабель напрямую к плате. Надо просто напаять гребенку. Если нет под рукой гребенки — подойдут любые куски жесткой проволоки — хоть скрепку канцелярскую разогни и кусачками порежь. И не надо туда 5 вольт совать, а то еще и консоль убьешь. 🙂 serial-ttl для того же и собирается, чтобы напряжений больших не было….
