Unable to set software breakpoint Опции

[el123]

перешел на linux.
Теперь вместо iar для программирования мк at91sam7x использую gcc
Создал тулчейн. Установил эклипс. Установил embeddedCDT.
Все компилится, прошивкается, и даже ходил по строкам кода. Т.е. отладка есть. Видны регистры, видна память.
Но, не работают точки останова.

К примеру ставлю в эклипсе брек поинт, нажимаю F8. И отладчик туда не попадает, он её игнорирует, если нажать на паузу, отладка остановится, у меня к примеру на while(1).

В общем подскажите что за дела?

У меня at91sam7x. Отладчик segger j-link.
Конфиг для openocd:

В общем что нужно сделать что бы можно было ставить точки?
