| 7 | ## Building |

| 9 | 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`. |
| 10 | 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`. |
