Hi, sorry for the delay. I have solved the issue. The PPI was working well on RTC events with previous implementation only. But the thing that confused me so much and ate all my time was IRQ_CONNECT. Instead of rtc_handler from my code , it should be nrfx_rtc_2_irq_handler. Which is declared in rtc.h and defined in rtc.c

The above code works only with this change

IRQ_CONNECT(DT_IRQN(DT_NODELABEL(rtc2)),
	            DT_IRQ(DT_NODELABEL(rtc2), priority),
	            nrfx_rtc_2_irq_handler, NULL, 0);

Hi,

What is the problem that you face? Do you get any errors?

Hi, thanks for the reply. I was able get PPI up through nrfx but not RTC.
I see that you have suggested this unofficial github example in this ticket. and followed it , but couldn't get it run. you can see my code snippet in the starting question. Is there anything wrong with my code. I am using nrf52840 on a custom board.

Hi Shiva,

You can take a look at this sample as well as this one.
