Проблема с программирование с помощью Openocd Опции

[bmstudeman]

Здравствуйте.

Не могли бы вы помочь новичку. Хочу залить программу на контроллер AT91SAM7S256 через Openocd. Программа самая элементарная - мигание индикаторов. При выполнении скрипта загрузки во флеш выдаются следующие сообщения:

C:\AT91SAM7S\OpenProj>openocd_go_flash
Open On-Chip Debugger (2008-03-01 20:00 CET) svn: 423

Info: jtag.c:1304 jtag_examine_chain(): JTAG device found: 0x3f0f0f0f (Manufacturer: 0x787, Part: 0xf0f0, Version: 0x3)

Warning: arm7_9_common.c:724 arm7_9_poll(): DBGACK set, but the target did not end up in the halted stated 1
Info: options.c:50 configuration_output_handler(): Timed out waiting for reset

В результате программа НЕ выполняется. Во всяком случае ни сразу, ни после нажатия кнопки reset.
В чем тут может быть дело? Помогите, пожалуйста. Буду очень признателен.

Ниже привожу скрипты.
