micro-ecc compilation error

[kumar]

I have uploaded the Image with Keil µVision compilation errors, included Files in main.c and on the left side the compilation of micro_ecc_lib_nrf52.lib file using " build_all.bat " bash script file and mingw32-make.

Regarding the Nordic Info Center about files missing or to be updated, I think It was my misunderstanding about missing files in SDKv13.0.0 as stated in the first NOTE section of this link infocenter.nordicsemi.com/index.jsp

Thanks and regards, Kumar

Hi,

You need to add the compiled library to your project in addition to the header files (the source files of micro-ecc should not be added).

The library needs to be compiled using the scripts build_all.bat/.sh, found in external/micro-ecc directory, or as described on this page, and you need to include the correct library depending on your hardware. This is the paths for SDK v14.2.0.

nRF51 series:

external\micro-ecc\nrf51_keil\armgcc\micro_ecc_lib_nrf51.lib

nRF52832/nRF52840:

external\micro-ecc\nrf52hf_keil\armgcc\micro_ecc_lib_nrf52.lib

nRF52810:

external\micro-ecc\nrf52nf_keil\armgcc\micro_ecc_lib_nrf52.lib

Best regards,

Jørgen

Hello Sir, Thankyou for your quick response. I have followed the steps you have stated in your response and compiled the project in keil v5.05. But, I still get the same errors even after including the compiled (using build_all.bat) library file. By the way, I have been using Nordic nRF5_SDK_v13.0.0_04a0bfd software version and I have also read in the Nordic info center that the v13.0.0 version has been missing some files related to cryptography or so. I request you to please help me at this point. I would also like to upload an image of the errors but I think I cannot in this comment section.

Thanks and regards, Kumar

Could you post a link to the infocenter where you have read that? You can upload an image by editing your original question.

I have edited my original post and uploaded the image and link. Please have a look and hope you could help me out! Thanks!

Have you enabled the ECC library in your sdk_config.h file?

// <q> ECC_ENABLED  - ecc - Elliptic Curve Cryptography Library
 
#ifndef ECC_ENABLED
#define ECC_ENABLED 1
#endif

Thankyou so much, it Worked! But strangely only when I include "ecc.c" into the project. If I don't include the "ecc.c" then the error remains the same even after the ECC_ENABLED bit is set in the sdk_config.h file. Anyways, I can now compile without errors and I am very greatful for your timely suggestions. Thankyou once again.

Regards, Kumar
