Hi Max,

you have skipped the last step, i.e.

5. Run make to compile the micro-ecc library.

You have to run make in the InstallFolder\external\micro-ecc\nrf52_armgcc\armgcc folder in order to compile the micro_ecc_lib_nrf52.a library, which in turn is used by the secure bootloader project. If you do not have make installed, then you have to install the GNU ARM Eclipse Windows Build Tools package, which can be downloaded from here.

Best regards

Bjørn
