unable to build software using Keil MDK

[Ruuddb]

L.S.,

I'm trying to build an "Arduino" port for the nrf52840 (Seeed board).

When building an example I'm getting the following errors during the link phase:

.\Objects\nrf52_SoftwareSerial.axf: Error: L6218E: Undefined symbol SaSi_LibInit (referred from adafruit_nrfcrypto.o).
.\Objects\nrf52_SoftwareSerial.axf: Error: L6218E: Undefined symbol SaSi_LibFini (referred from adafruit_nrfcrypto.o).

What do I need to do to resolve this?

Hi

From your last reply, did you get anywhere? From what I can see you need to add Cryptocell to your project in sdk_config.h with the following:

#define NRF_CRYPTO_ENABLED 1
#define NRF_CRYPTO_BACKEND_CC310_ENABLED 1
#define NRF_CRYPTO_BACKEND_CC310_BL_ENABLED 0
#define NRF_CRYPTO_BACKEND_MICRO_ECC_ENABLED 0

Include the path to these files and add those to project settings:

/external/nrf_cc310/lib/cortex-m4/hard-float
/external/nrf_cc310/include

As well as initialize crypto in your code with an include and an init function:

#include "nrf_crypto.h"

void crypto_init(void)
{
ret_code_t ret = nrf_crypto_init();
if (ret != NRF_SUCCESS) {
// Handle error
}
}

Best regards,

Simon

Hello Simon,

Well it' builds, but still crashes on a hardware problem somewhere. 

The software has been build by someone else, I'm using the code on:

https://github.com/Seeed-Studio/Adafruit_nRF52_Arduino

which should work.

So, I'm not using the nordic SDK.  Examples from your SDK (using Keil V5) seem to work ok.

But we are using V6...

REgards,

Ruud
