Thanks Jorgen. The problem is that I didn't initialise the Low-Frequency clock before calling nrf_crypto_init() which would initialise the RTC.

So, I added the code for initialising the Low-Frequency clock, before calling nrf_crypto_init() function and everything's working great! Such a silly mistake but hey, we live, we learn and we forget 😛

Thanks for your help. I appreciate it.

Thanks for the response.

I'll try to investigate why the program never reacher the interrupt handler even after it's triggered. Probably not initialised correctly. Shall update this post after the results.

Hi,

Correct, RTC2 is used by the IEEE 802.15.4 radio driver and OpenThread stack, see Thread nRF52840 peripheral requirements. The example you mention does not include BLE, and will therefore not use a softdevice. If you do not plan to use a softdevice, you should be able to use RTC0 for the Optiga Trust X library.

Best regards,
Jørgen
