Abstract

This document is intended to guide developers to integrate the EdgeLock® SE050 security chip on the NXP MIMXRT1180EVK development board to achieve hardware-level security enhancement. The SE05x can be easily connected to any system, with the minimal requirements - only power and two pins for I2C are required. Additionally, it is easy to integrate thanks to the support of the Plug&Trust Middleware for the software on the host.

Hardware Prerequisite

Host Platform: MIMXRT1180EVK

Expansion Board: OM-SE050X

Hardware setup

1. Configure the OM-SE05xARD jumpers as below[1]:

2. Configure the jumpers on MIMXRT1180-EVK as default[2]:.

Software Integration

There are two methods to integrate the OM-SE05xARD to MIMXRT1180-EVK, one is based on SDK, and the other is based on zephyr. Users may select either of them according to their requirements.

SDK Integration:

Platform files generation

The nano package offers a very simple way to integrate the MW on any MCU platforms, Users just need to add/modify the platform specific files which are maintained in simw-nanopkg/lib/platform folder.

Applying the attached patch, you may easily have them as above.

Import I2C demo project as a starting point

We recommend starting the integration based on the SDK I2C demo as this project contain the sdk I2C driver code already, so for RT1180, we import evkmimxrt1180_lpi2c_polling_b2b_master_cm33 .

exclude the board files and use the ones from the nano package instead.

import source files from the nano package

Import the example code, here we select ex_se05x_crypto.c and main.c.

Add definitions as below for nano package building , as well as the including paths.

Zephyr Integration:
The integration is much simpler than SDK integration, since the platform specific files are already there, users just need to add the board overlay file for MIMXRT1180-EVK manually. The attached overlay file should be placed in the folder such as "workspace/modules/crypto/nxp-plugandtrust/examples/se05x_crypto/zephyr/boards/".

Please note the guide for Zephyr Integration is ready on https://github.com/NXPPlugNTrust/nano-package/blob/master/zephyr/readme.rst , while the tested zephyr version still stays on v3.7.0, which hasn't supported MIMXRT1180-EVK yet. To have the support for MIMXRT1180-EVK, we have to use the latest zephyr, with a modified west.yml file.

Here are the steps we need to go through:

$ rm workspace/ -rf
 $ mkdir -p workspace
 $ cd workspace/
$ git clone https://github.com/NXPPlugNTrust/nano-package.git
//Edit ~/workspace/nano-package/zephyr/west.yml as below
$ cd ..
$ west init -m https://github.com/NXPPlugNTrust/nano-package.git --mf ~/workspace/nano-package/zephyr/west.yml ~/workspace/
$ cd workspace
$ west update

Build examples:

$ cd workspace/
$ west build -b mimxrt1180_evk/mimxrt1189/cm33 modules/crypto/nxp-plugandtrust/examples/se05x_crypto/zephyr/ --pristine
