Приветствую!
Ремонтирую точку AirGrid M5 HP версии XW. Это мой первый случай ремонта подобного оборудования.
Lan порт подает какие-то признаки жизни, но процессор не сбрасывается кнопкой, по крайней мере нет индикации сброса.
Решил подключиться к последовательному порту для просмотра процесса загрузки.
Вот что увидел:
Первый момент - это:
[ 0.274000] ..........PCIe WLAN H/W not present.
Из чипов в радиотракте у этого варианта только AWL5905 - это просто усилитель, т.е. может его и не должно быть этого "PCIe WLAN" хардваре ?
Второй момент, невозможность распаковки имиджа - это битая флэш ? Что с этим можно сделать, что-то типа через urescue мягкий вариант или это замена микросхемы со всеми вытекающими последствиями ?

Из чипов в радиотракте у этого варианта только AWL5905 - это просто усилитель, т.е. может его и не должно быть этого "PCIe WLAN" хардваре ?
Второй момент, невозможность распаковки имиджа - это битая флэш ? Что с этим можно сделать, что-то типа через urescue мягкий вариант или это замена микросхемы со всеми вытекающими последствиями ?
