Hi Amritpal,

Please try setting CONFIG_MBEDTLS_VANILLA_BACKEND=y and CONFIG_CC310_BACKEND=n. In https://github.com/NordicPlayground/nrfxlib/blob/master/nrf_security/Kconfig the default is CC310_BACKEND, and there is currently no non-secure callable support, so you can't access the cryptocell peripheral, so you should try to do it in software instead.

Hi Amanda,

Yes, I am using nrf9160dk_nrf9160ns as the board.

The default CONFIG_NORDIC_SECURITY_BACKEND is not enabled in the https_client project. I manually tried enabling it from the Configure nRF Connect SDK Project, but once I do that the error comes up in configuring the project.

Hi Amritpal,

[quote user=""]I got the same result if I set CONFIG_NORDIC_SECURITY_BACKEND=y in https_client project[/quote]

The default setting of CONFIG_NORDIC_SECURITY_BACKEND is enabled in the https_client sample, and I don't see any building issue. Are you building with nrf9160dk_nrf9160ns?
