Hey, I just wanted to share that I stumbled with this problem too and the suggested solution didn't work for me.

In addition to enabling

I also had to enable the following macros in sdk_config.h

As it's described in the RNG Configuration section.

I get

Undefined reference to " CRYS_Rndinit" error.

All the error related to ,

Cc310_backned_rng.o,init.o ,ecc.o files

I have been going through the same problem as above.

I have also enabled all config in sdk_config.h file .

Did you set config to enable HW RNG in the CC310?

Backend	Enabled define
CC310	NRF_CRYPTO_BACKEND_CC310_RNG_ENABLED
nRF HW RNG	NRF_CRYPTO_BACKEND_NRF_HW_RNG_ENABLED

Thanks for your response, now i am able to compile the project and calling the function nrf_crypto_ecc_key_pair_generate. but still i am not able to create key pairs. when i call the nrf_crypto_ecc_key_pair_generate function it return 0x00008502 error code. i had enabled NRF_CRYPTO and NRF_CRYPTO_CC310_ENABLED macros int the sdk_config.h and also memory allocator had set to default in the sdk_config. when i debug the app, i saw that nrf_crypto_ecc_key_pair_generate function itself invoke CRYS_ECPKI_GenKeyPair function and this function return CRYS_RND_INSTANTIATION_NOT_DONE_ERROR. do you know how can i sove this problem??

thanks

Hi,

The functions are defined in the file nRF5_SDK_15.2.0_9412b96\components\libraries\crypto\backend\cc310\cc310_backend_ecc.c.

Note that you need to enable the following configs in sdk_config.h for the functions to be compiled in:

Best regards,
