I am trying to do RTC wakeup interrupt using STM32L412RBT6 microcomtroller in baremetal c, but the interrupt is not firing, below mentioning my code. int main(void) { LedConfig(); Tim6Config(); RTC_ClockConfig(); RTC_Init(); /* Loop forever */ while(1) { GPIOB->BSRR |= (1U...
TL;DR: I see that the WUTF bit in RTC ISR register is correctly set after the RTC wake up timer period elapses, but the interrupt service routine is never entered. RTC interrupt is enabled in NVIC though, and the interrupt service routine function name matches the o...

wake_up_interruptible是个非常重要的调用,在它执行后,系统会唤醒睡眠的进程,它们等待的RTC中断到来了。这部分内容涉及等待队列,我们也会在以后的文章中详加解释。 最简单的改动 我们来更进一步感受中断,非常简单,我们要在RTC的中断服务程序中加入一条printk语句,打印什么呢?“I’m coming, interrupt!”。

My wake up interrupt using RTC is on semaphore and xSemaphoreGiveFromISR function is called from ISR during RTC wake up interrupt, do you think this is the problem as this requires context switch while scheduler is suspended.Any help or suggestion will appreciated.Regards,Heena 0 Kudos Reply...
