-

i found problem running program on stm32f100rbtx. using eclipse + zadig + openocd. working fine until tried handle interrupts.

looking through google think problem in startup file , assembler file. looked proper files without success. me repair file or 1 ?

link assembler file

link startup.s

pastebin . com/wsrxr2yi -- vectors.c (have no reputation)

my main:

#include "stm32f10x.h" #include "mygpio.h"  typedef my_gpio<gpioc_base,8> blueled; typedef my_gpio<gpioa_base,0> button;  int main(void) {     //gpio_inittypedef gpio_initstructure;      volatile int dly;     rcc->apb2enr |= rcc_apb2enr_iopcen | rcc_apb2enr_iopaen;     rcc->apb1enr |= rcc_apb1enr_tim3en;      blueled::setmode(pinmode_output_2mhz);      tim3->psc = 23999;           // set prescaler 24 000 (psc + 1)     tim3->arr = 1000;              // auto reload value 1000     tim3->dier = tim_dier_uie; // enable update interrupt (timer level)     tim3->cr1 = tim_cr1_cen;   // enable timer      nvic_enableirq(tim3_irqn); // enable interrupt tim3 (nvic level)      while (1) {         for(dly = 0; dly < 500000; dly++)             ;         blueled::sethigh();     } }  void tim3_irqhandler() {     ///irq flag cleared  -- program never here(checked) }
