Linking Issue in nrf_crypto_init.c

[Meriba]

Hello

I have ported the example project "nrf_crypto_aes_pca10056" to my one project. But now I'm not able to building the project anymore.
Segger Embedded Studio will show the follwing message:

Output/.../nrf_crypto_init.o: In fuction 'nrf_crypto_init'
undefined references to '__stop_crypto_data'
undefined references to '__start_crypto_data'

It looks like, that the issue happens at this line into the "nrf_crypto_init.c":
// Create a named section for crypto backend data
NRF_SECTION_DEF(crypto_data, const nrf_crypto_backend_info_t);

Probably I missed to add a preprocessor definition or so, but I can not find any difference there.
I'm very glad about advice or ideas.

Hi Hanno,

You need to define the symbols for "__start_crypto_data" and "__stop_crypto_data" in the flash_placement.xml file under the pca10056\s140\ses folder in your project. Just copy from the .xml file in the original crypto example.

Best regards,

Marjeris

Hi Marjeris

Thank you very much, you are right, the define symbols in the flash_placement.xml file was missing.

Best regards
Hanno
