[z8491]

Началось как у всех после неудачной прошивки
dd-wrt
Роутер был в циклической перезагрузке, он стартовал, даже успевал выдать адрес по DHCP и тут же перезагружался, и так каждые 30 секунд примерно.

Прописав на сетевой карте статический адрес 192.168.1.2 можно было успеть попинговать его и даже попытаться начать заливку по tftp.

Советы по удержанию кнопки reset в течение 30 секунд на включенном, потом 30 на выключенном роутере, и еще 30 на снова включенном, никакого результата не принесли.

После нескольких попыток удалось подключить консоль
к DJ2
И вот тут я сделал роковую ошибку по незнанию комманд CFE
После ввода
CFE> nvram erase
*** command status = 0
CFE> go
И перезагрузки тела,
горят только тускло power и internet
ни пинга ничего консоль больше не загружеться

аппарат выкинуть жалко

как сделать JTAG не разобрался


log что удалось сохранить
CFE> nvram erase
*** command status = 0
CFE> go
