Micro-ecc library won't compile

RE: Micro-ecc library won't compile

Unfortunately, even I am not able to compile the "ecc.h" without errors. As described in this post, I have included the precompiled library of micro-ecc and just included the header file in main.c. I get the same errors even after including the library file. And I have also seen that the .c files are not added to the project. I am stuck with this point and unable to come out of this problem. At this stage it seems like I have to port the whole project into eclipse or so. But I would like to use Keil Compiler instead of GCC compiler for the Project. Any Suggestions would be of great help!

Thanks and regards, Kumar

The softdevice is not compiled, it is delivered as precompiled hex file. You can find it in [SDK_ROOT]\components\softdevice\s132\hex. It can also be downloaded from our webpage (see compatibility matrix for supported softdevice versions for SDKs).

I finally managed to achieve something. After hours and hours spent experimenting and manually adding/importing tons of libraries, errors have dissapeared but then I faced up with image exceding maximum allowed 32KB (free uVision). I managed to exclude the whole ECC library (I won't need it for now) and then it has been built successfully. But for some reason, the SoftDevice .hex file has not been created. I can't find it in RTE/_nrf52832_xxaa nor in RTE/Device/nRF52832_xxAA. Application's .hex is being created successfully, inside _build folder. What may be the problem?

You should not include the c-files of micro-ecc, only header files and the precompiled library.

But should I include .c and .h in the project, if I compiled it outside of Keil and added .lib?

The "Undefined symbol" errors are either due to .c source files not being included in the project, or the modules not being enabled in sdk_config.h. The missing uECC.h error indicates that micro-ecc source is not located in the correct location (or you have removed the include path from the project settings). Make sure you have uECC.h, and the rest of the micro-ecc repository in the path nRF5_SDK_13.0.0_04a0bfd\external\micro-ecc\micro-ecc.

If you have renamed the SDK directory. the SDK version should be reflected in the top of the file release_notes.txt, found in documentation directory.

How to see which version of SDK it is? I downloaded it somewhere in March this year, from the official website. I'm using Keil uVision to write code, compile it and transfer files to nRF52 board, but I've compiled micro-ecc via Bash on Ubuntu on Windows, using gcc arm eabi and make. I'm trying to port "experimental_ble_app_hrs_nfc_pairing" example into clean "ble_app_uart" example. I have a code based on "ble_app_uart" on which I need to add pairing functionality.

Which SDK version are you using, and what example are you testing this on? Are you using Keil or GCC compiler?

Can you, please, give me step-by-step instructions? I just can't get it to work. I deleted the .c file I've added, and I removed path to the folder containing the .c file in project options, and then I've added this .lib file by clicking right click on Application -> Add existing file. But it won't recognize it, I'm getting this

Also I've tried to add this .lib file to the original "experimental_ble_app_hrs_nfc_pairing" example but I'm getting this:

Have you added the .c files to Keil? You should not do that, you should use the .lib file found in external\micro-ecc\nrf5x_keil\armgcc folder. If you have compiled the micro-ecc library, the unmodified example project in the SDK should compile. If you are having trouble, try with a fresh copy of the SDK, to make sure you did not change anything in the project.

XploD — Sat, 09 Sep 2017 21:44:10 GMT

Yes I did. But I don't know what to do next, uVision is still trying to compile the C file itself. How do I tell it to use already compiled .o and .d files?

Jørgen Holmefjord — Fri, 08 Sep 2017 08:43:16 GMT

Did you download and compile micro-ecc according to the instructions in the SDK documentation?
