Undefined reference to `CC_AESCCM_Init' for AES CCM

[Zoptune]

Hi,

I want to use AES CCM in my project (I want to try both CC310 and mbedTLS).

When I compile my project, I have undefined reference to 3 functions that are located in "crys_aesccm.h"

1> Output/.../Obj/cc310_backend_aes_aead.o: In function `backend_cc310_crypt':
/components/libraries/crypto/backend/cc310/cc310_backend_aes_aead.c:277: undefined reference to `CC_AESCCM_Init'
/components/libraries/crypto/backend/cc310/cc310_backend_aes_aead.c:301: undefined reference to `CRYS_AESCCM_BlockAdata'
/components/libraries/crypto/backend/cc310/cc310_backend_aes_aead.c:320: undefined reference to `CRYS_AESCCM_Finish'
1> Output/.../nrf_crypto_init.o: In function `nrf_crypto_init':
/components/libraries/crypto/nrf_crypto_init.c:86: undefined reference to `__stop_crypto_data'
/components/libraries/crypto/nrf_crypto_init.c:86: undefined reference to `__start_crypto_data'

I have enabled NRF_CRYPTO and CC310_BACKEND and CC310_AESCCM in the sdk_config.h. I also have the same includes as in the nrf_crypto/aes_ccm example.

Do you guys have any idea where the problem is coming from ?

I can post my full config file if necessary.

Thanks

PS : I'm using latest SDK (15.3)

Hi,

Yes, it would be very useful to see your sdk_config.h file. I do not see how you could get exactly this error though, so it might not be needed, but it could be useful to see the rest of your project as well, in addition to the full log from the build process.

Ok, sorry for the late answer, I was working on other things.

I found where was the problem :

- for the first 3 undefined reference, I was working on a build configuration where the static lib (.a file) was not included

- for the last 2 undefined reference, I had to add a section for the crypto_data in the flash_placement.xml file (I looked at the flash_placement.xml file in the aes_ccm example).

Now it compiles and run perfectly
