Micro-ecc issue?

[amarin]

Hi,

I am currently trying to run the DFU over UART example using my nrf52840 dk. I am using sdk v15.2.0. I followed the following instructions found in the Nordic Infocenter: 

1. Install version 4.9-2015-q3-update of the GCC compiler toolchain for ARM. You can use ARM's Launchpad to find the toolchain for your operating system.
2. Make sure that make is installed (see, for example, MinGW, GNU Make, or Xcode).
3. Clone the micro-ecc GitHub repository into <InstallFolder>\external\micro-ecc\micro-ecc.
4. Enter the subdirectory for the SoC and the toolchain that you are using to build your application:
   • InstallFolder\external\micro-ecc\nrf52_keil\armgcc
   • InstallFolder\external\micro-ecc\nrf52_iar\armgcc
   • InstallFolder\external\micro-ecc\nrf52_armgcc\armgcc
5. Run make to compile the micro-ecc library.

I thought I was able to follow all of the instructions, however, as soon as I build the solution the error in the picture shows up:

I think it has to doing something wrong when installing the micro-ecc compiler, but I could be wrong. Please help!

Hi, 

Could you run make under nRF5_SDK_15.2.0\external\micro-ecc\nrf52hf_armgcc\armgcc and then build the porject again?

Please let me know this can work or not. Thanks.

I ran a make under the directory you said and this was given:

After building the solution, I was given the same error.

I was able to get rid of some of the errors by following this solution: https://devzone.nordicsemi.com/f/nordic-q-a/48801/contact-us-for-link-errors

However, I am still getting some errors seen in the picture.
