Hi,

The bootloader depends on an external crypto library(uECC) to build. This library is not included in the SDK and must be built from source.

To build the library, you first need to install the following tools:

 - GNU Make. There are several ways to get this application. It's for instance included in the "build tools" package here: https://github.com/gnu-mcu-eclipse/windows-build-tools/releases/tag/v2.11-20180428/. make.exe must be added to %PATH%

 - Git

 - GNU ARM toolchain version 7 2018-q2-update (download link)

Once you have installed the above, you can run the build_all batch file in \nRF5_SDK_15.3.0_59ac345\external\micro-ecc. The script will fetch and compile the library for you.
