ARM, RISC-V контроллеры

Нужен совет по бутлоадеру. Использую OpenBLT, гружу программу с SD. Сначала запустил их пример на Discovery F4 (немного переделал). Теперь переделываю свою программу под Discovery F4 чтобы ее запускал бутлоадер. Проблема в том, что, похоже, что-то не так с таблицей векторов. Инициализирую IRQ SysTick. Цикл крутится, потом программа прыгает в непонятное место вместо обработчика SysTick. Изменение адресации учел. Вот выдержка из icf

define symbol __ICFEDIT_region_ROM_start__ = 0x0800C000; define symbol __ICFEDIT_region_ROM_end__ = 0x081FFFFF; define symbol __ICFEDIT_region_RAM_start__ = 0x20000000; define symbol __ICFEDIT_region_RAM_end__ = 0x2002FFFF; /*-Sizes-*/ define symbol __ICFEDIT_size_cstack__ = 0x10000; define symbol __ICFEDIT_size_heap__ = 0x4000;

Внимательно изучил http://www.feaser. …ual:ports:armcm4_stm32 remove the following lines from function SystemInit() как сказано сделал. А вот как мне правильно отредактировать startup.s не могу понять.
