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:
