https://devzone.nordicsemi.com/f/nordic-q-a/65950/cc310-rng-hard-fault-during-ozone-debugHi, I&#39;m trying to run the JLink debugger using Ozone to debug my program. When I run nrf_crypto_init(), I encounter a hard-fault. The program is not experiencing any problem when I run the problem without debugging.

It seems to be a trouble on our end, when I removed the soft device and bootloader I am able to step pass the crypto_init call.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/269934?ContentTypeID=1Wed, 16 Sep 2020 17:49:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a1390e0c-26f1-449c-98f1-6ef4f930af74Einar Thorsrud<p>Hi,</p> <p>I have been using Ozone to debug CC310 code myself without any problems. Do you get this problem also if testing with a SDK nrf_crypto example that uses the CC310 backend? Also, which SDK version do you use and which Ozone version, and which toolchain? If you have no progress,&nbsp;can you upload a minimum failing sample project you could upload here so that I can test on my side?</p><div style="clear:both;"></div>
