I backported nrf_crypto libraries from SDK 15.2 to be able to use high level API. It all seems to work with initilizing okay but it ends with hardfaulten-USTelligent Community 13Mon, 29 Apr 2019 13:20:42 GMThttps://devzone.nordicsemi.com/thread/184340?ContentTypeID=1Mon, 29 Apr 2019 13:20:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a717c58c-b443-4a8d-913b-72e61a5a1f99Einar Thorsrud<p>Hi,</p> <p>The nRF52840 was not fully supported until SDK 15.0.0. Also, the port of the CC310 run-time library was incomplete at this point, in a early untested alpha-version. Therefor I recommend you migrate to SDK 15 (15.3 is currently the latest and greatest) for any work on the nRF52840 in general, and CC310 in particular.</p><div style="clear:both;"></div>
