Missing EXTI IR handler code I'm using the EXTI1 interrupt and defined the EXTI1 handler like this:void EXTI1_IRQHandler(void)
{
__HAL_GPIO_EXTI_CLEAR_IT(GPIO_PIN_1);
if (GPIOA->IDR & 0x0100 {
EXTI->PR = 1;
(void) EXTI->PR;
NVIC_ClearPendingIRQ(EXTI0_IRQn);
NVIC_EnableIRQ(EXTI0_IRQn);
fun1();
} else {
NVIC_DisableIRQ(EXTI0_IRQn);
EXTI->PR = 1;
(void) EXTI->PR; // wait for hardware
NVIC_ClearPendingIRQ(EXTI0_IRQn);
}When I look at the generated list file, I find this assembly code:000001d4 <EXTI1_IRQHandler>:
while (__HAL_RTC_ALARM_GET_FLAG(hrtc, RTC_FLAG_ALRAWF) == RESET);
1d4: 4bab ldr r3, [pc, #684] ; (484 <_Min_Heap_Size+0x84>)
1d6: 2102 movs r1, #2
if (count-- == 0U)
1d8: 4aab ldr r2, [pc, #684] ; (488 <_Min_Heap_Size+0x88>)
1da: b5f0 push {r4, r5, r6, r7, lr}
1dc: 6159 str r1, [r3, #20]
1de: 6912 ldr r2, [r2, #16]
1e0: 0792 lsls r2, r2, #30
1e2: d525 bpl.n 230 <EXTI1_IRQHandler+0x5c>
hrtc->Instance->ALRMAR = (uint32_t)tmpreg;
