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?)

https://infocenter.nordicsemi.com/index.jsp?topic=%2Fsdk_nrf5_v16.0.0%2Flib_crypto_config.html

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,

We have tried the following methods based on your suggestions,

1. 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,

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