Hi Srinivas,

I don't know where it hangs in your code, but you can find our nrf crypto examples in the nrf_crypto directory here: \nRF5_SDK_17.0.2_d674dde\examples\crypto\nrf_crypto that you can use references.

Hi Vidar,

Thanks for your reply. Even after using CC310 with "nrf_crypto" front end with mutex provision also it is hanging between multiple calls.

Any body is faced the same issue with CC310 HW RNG and With Crypto Functionalities. If you have any source code could you please share with us , we will use the same .

Hi,

Please consider using the nrf_crypto module with the cryptocell as the backend instead of trying to work directly with the SaSi API. From the code you posted I see you are not using mutex to ensure exlusive access, so the problem might be that you are calling "CRYS_RND_GenerateVector" while the cryptocell HW is busy with another task.
