Unable to utilize Crypto Hardware backend feature on nRF52840 Dongle

[HY Chang]

Hi,

I m using nRF52840 dongle to setup the nRF5_SDK_17.0.2 .

Besides, the related software and the Segger Embedded Studio are installed.

 

Occurred Problems :

When enabling Crypto Hardware backend feature on nRF52840 Dongle, I’ve got some errors below.

To tackle with those errors, I try to solve them according to the reference link,
however I still have some questions:

1. Is it possible to set the NRF_CRYPTO_BACKEND_CC310_ENABLED  define to 1?
( Should nRF52840 dongle be included in nRF52840?)

2.If setting the NRF_CRYPTO_BACKEND_CC310_ENABLED  define to 1 is feasible,
how to solve those errors which seems like an “undefine reference” problem?

I’ll be very appreciate if anyone can answer those questions.

Hi,

Would you be able to upload your projet here or in a private support ticket so I can take a look? It's a bit difficult to say what's missing without having the project in front me.

Best regards,

Hi,

Please make sure you are have the same crypto related configuration settings and source files as in the ECDSA Example (\nRF5_SDK_17.0.2_d674dde\examples\crypto\nrf_crypto\ecdsa). The linker errors indicate that you either missing some of the necessary source files, or that these files have not been enabled in sdk_config.h
