Hi,

Have you remembered to include the cc310 runtime library in your project?

We have tried the following methods based on your suggestions,

We’ve compared the difference between sdk_config.h of our project and ECDSA Example, and put the missing configuration into our project one by one, and build it.

2. We also change sdk_config.h of nRF52840 Dongle by adding nRF52840 DK sdk_config.h after it. Besides, according to nRF52840 Dongle Programming Tutorial, we modify it to PCA10059 and build it, however, the same error still occurs and it is not resolved.

3. Apart from this, we are not sure about “the modified option hint” in the picture below, is it possible to cause the error?

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

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,

Vidar
