mbedtls_aes error

[HDuc]

Hi all,

I tried to merge a mesh application into the nRF5 SDK BLE example.

But, I have encountered the errors below:

"Output/........... Debug/Obj/ctr_drbg.o: In function `mbedtls_ctr_drbg_seed_entropy_len':
undefined reference to `mbedtls_aes_init'
undefined reference to `mbedtls_aes_setkey_enc'

Output/........... Debug/Obj/ctr_drbg.o: In function `mbedtls_ctr_drbg_random_with_add':
undefined reference to `mbedtls_aes_crypt_ecb' "

I would like to know where it comes and how to fix it.

Many thanks in advance.

I think I understand the problem, but I do not know how to resolve.

There are two files "aes.c", one in mesh/core and the other in nrF_TLS. I removed the file "aes.c" in nrF_TLS. and the file "ctr_drbg.c" in nrF_TLS is not compatible with the file "aes.c" in mesh/core.
