This is news to me, seems like Timeslot does not allow the use of RNG. below is copy paste from S110 SDS

When a timeslot is granted, the application has exclusive and realtime access to the normally blocked RADIO, TIMER0, CCM, AAR, and PPI (channels 14 – 15) peripherals

Looks like RNG is still protected, you can fix this for now by using SOC API for accessing RNG. I will go to work tomorrow and dig for some internal details of this behavior.

I removed the optimized in IAR. But, the situation is same. When i call the "NRF_RNG->CONFIG |= RNG_CONFIG_DERCEN_Msk;"，the program will lack in "HardFault_Handler". I am using rng in timeslot callback with S110. Do i need to use the SOC API instead of calling rng driver? ex:"sd_rand_application_vector_get ", do you help to give a simple example? thanks a lot

It does not seem correct that it stops in nrf_rng_error_correction_enable. Please try again by remove optimizations while debugging in Keil and let us know exactly where it fails and with what error.
