RE: nRF5340 RNG peripheral

Wow seems more complicated than i would have thought. I was looking at the peripheral registers and there is a start,stop,and value register. i guess i just cant read the value register when valrdy is set?

Hello,

We actually have the nRF5340: nRF RPC Entropy sample that does exactly this. The application core uses the nRF RPC library to request/retreive RNG data from the net core.

Best regards,

Vidar

Edit: The sample application linked to above is only relevant if there is a particular requirement for the application core to use the RNG peripheral on the network core. Otherwise you should use the RNG built into the cc312 via the entropy driver: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/samples/drivers/entropy/README.html
