не могу запустить kgdb, kernel debugger Опции

[federal]

День добрый!

Столкнулся с проблемой для cortex-A8.
Не загружается отладчик ядра во время стартапа ядра.
Делаю вроде все правильно, по инструкции http://www.linuxforu.com/2011/09/kernel-sp...ggers-in-linux/
ядро версии 3.x.x ( 3.2.18 ).
Отладчик ядра запускаю по 232 порту, т.е. over console( ввиду того, что в ядре версии > 3.x.x kgdb over ethernet исключили ).

параметры, которые я дополнительно передаю ядру:
kgdboc=ttyO0,115200n8 kgdbwait

пробовал и так:
kgdb8250=ttyO0,115200n8 kgdbwait

но все равно, во время старта kgdboc не подгружается.

Кто нибудь может подсказать, как запустить его и в чем может быть проблема?
Есть какие нибудь идеи?

опции для kgdb включил те же самые, но kgdb не включается.
