ARM startup code Опции

[doom13]

Приветствую.
Исходные данные:
1) LPC1766
2) ARM DS-5
3) CMSIS Packs Plug-in
4) GNU ARM OpenOCD
Проблема - при старте программы не происходит инициализация глобальных переменных. Как понимаю, надо добавить кусок кода (что-то типа __initialize_data и __initialize_bss) в startup.s + подправить scatter-file (пока используются стандартные для нового проекта)??? Аналогичный вопрос, но без ответа.
