Hi, I have an issue with the use of interrupts. I was using only the startup.s for LPC2368 and the compiler Realview. I use Timer, RTC and external interrupts. Everything was working fine during several months but now seems that sings are different, the interrupt are no serviced any more whereas the registers are set properly when interrupt requests or software interrupts are generated and when an IRQ interrupt occurs the micro is still waken up then I can know by reading the appropriate registers which IRQ need to be serviced and call the function (a duplicate of the function as irq functions can not be call by software) and this way do the job that the hardware should have done with the interrupt. I tried to use swi_handler.s but didn't change anything. Does anybody know what the problem is?
I didn't change anything in the way to handle interrupts, the clocks are enabled in PCONP, the Interrupt Service Routines for the apropriate interrups are installed with every interrupt handler functions, hardware and software interrupt requests are enabled to contribute to IRQ.
