Hi Leo

This error is expected, as the CryptoCell peripheral is not present on the nRF52833, so there's no point in trying to use it.

You will have to use a SW crypto backend, but you don't need to make any significant changes, as the nrf_crypto library provides a unified API. The only thing you need to do is to disable the CC310 backend in sdk_config.h by setting NRF_CRYPTO_BACKEND_CC310_ENABLED to 0, and enable the Oberon backend by setting NRF_CRYPTO_BACKEND_OBERON_ENABLED to 1, as well as setting the NRF_CRYPTO_BACKEND_NRF_HW_RNG_ENABLED to 1. You can compare with the sdk_config.h of the pca10040 project to see how this should be done, and they should be identical with regard to crypto configuration.

Best regards,

Simon
