Hi Jianxuan,

I've included it as an attachment in my previous now, wasn't able to do that earlier today for some reason.

Hi Vidar,

Thanks for your kind support!

I cannot access to dropbox website, which is forbidden.

Could you share your project on Nordicsemi website?

Thanks,

Jianxuan

Hi Jianxuan,

I have added nrf crypto/cc310 aes ecb to the ble_app_uart example in SDK 15.2.0 (devzone.nordicsemi.com/.../ble_5F00_app_5F00_uart_5F00_cc310_5F00_aes.zip). You may "diff" sdk_config.h and the *emproject file against the original ble_app_uart example to see the changes I made.

uECC is an external dependency, you can follow the instructions provided in "micro ecc backend" if you want to install it. However, it is not needed since you intend to use the cc310 (the example include support for all backends).

Regards,

Vidar

Hi Vidar,

Thanks for your reply!

According to your advice, I copy c_user_include_directories from nrf_crypto_aes_pca10056.emProject and paste to my project. The same mistake is happened.

I tried to build example of aes_all_cli, SES said:

cannot find ../../../../../../../../external/micro-ecc/nrf52hf_armgcc/armgcc/micro_ecc_lib_nrf52.a: No such file or directory

My SDK version is 15.2 and that of SES is 3.40.

Thanks,

Jianxuan

Hi Jianxuan,

g_nrf_crypto_aes_ecb_128_info is defined in cc310_backend_aes.c, is this file included in your project? You may use the aes_all_cli (\examples\crypto\nrf_crypto\aes\aes_all_cli) example to find other dependencies you may have missed. Tip: open the *.emproject file in a text editor and copy&paste relevant dependencies to your project, I find it faster than doing it within the GUI.

Best regards,

Vidar
