после установки MEMMAP = 1 или MEMMAP = 2 картина изменилась:

ниче не понимаю, никак не могу войти в прерывание.

1. Это кусок из стартапа:

MODULE ?RESET
COMMON INTVEC:CODE:NOROOT(2)
PUBLIC __program_start
EXTERN ?cstartup
EXTERN undef_handler, swi_handler, prefetch_handler
EXTERN data_handler, my_irq_handler, fiq_handler
CODE32 ; Always ARM mode after reset

~часть текста не показана~

org 0x18
__irq_handler
ldr pc,[pc,#24] ; Branch to irq_handler

org 0x1c
__fiq_handler
ldr pc,[pc,#24] ; Branch to fiq_handler

; Constant table entries (for ldr pc) will be placed at 0x20
; Exception vectors can be specified in C code by #pragma vector or by filling
; in the vectors below. The vector address is the ARM vector number + 0x20.

~часть текста не показана~

org 0x38
dc32 my_irq_handler
org 0x3c
dc32 fiq_handler
LTORG
; ENDMOD __program_start
ENDMOD

2. Разрешил прерывание каждую секунду (от RTC)
CIIR_bit.IMSEC = 1;

3. Инициализация прерывания
VICIntEnable = (1 << 13);
VICVectCntl0 = 0xd ;
VICVectCntl0 = VICVectCntl0 | 0x20;
VICVectAddr0 = (unsigned)RTC_isr_handler;

4. Обработчик.

__irq void my_irq_handler (void)
{
ISR_pntr isr_pntr;

isr_pntr = (ISR_pntr)VICVectAddr;
while (isr_pntr != 0)
{
VICVectAddr = 0;
(*isr_pntr)();
isr_pntr = (ISR_pntr)VICVectAddr;
}
}

__enable_interrupt() в функции main есть? =)

Как раз ее-то и не хватало. Спасибо.

прочитал, что в одном из слотов векторов прерываний должно храниться какое-то значение, чтобы чексумма векторов с этим значением давала 0, в связи с этим вопрос: это значение как то надо вычислять или оно само определяется??

Обычно его определяет программатор.
