Building MCUBoot with nRF52840 CC310 enabled

Pre-prerequisites

Clone nrfxlib next to the mcuboot root folder. So that it's located ../nrfxlib from mcuboots root folder.

Building

make sure root-ec-p256.pem is set as the certificate and that CONFIG_BOOT_SIGNATURE_TYPE_ECDSA_P256 is selected not CONFIG_BOOT_SIGNATURE_TYPE_RSA in prj.conf of boot/zephyr. Since it defaults to tinycrypt you'll have to go into menuconfig and change the implementation selection to cc310 or also set this in prj.conf.

mkdir build && cd build
cmake -GNinja -DBOARD=nrf52840_pca10056
ninja flash

Build a hello world example in zephyr and sign it with imgtool.py with the root-ec-p256.pem and flash it at FLASH_AREA_IMAGE_0.
