2 Hardware required

The EdgeLock SE05x works as an auxiliary security device attached to a host controller, communicating with through an I²C interface. To follow the instructions provided in this document, you need an EdgeLock SE05x development board and a i.MX 8M MCU board, acting as a host controller.

EdgeLock SE05x development boards ordering details

The EdgeLock SE05x support package provides development boards for evaluating EdgeLock SE050 and EdgeLock SE051 features. Select the development board of the product you want to evaluate. Table 1 details the ordering details of the EdgeLock SE05x development boards.

3 Boards setup

This section explains how to prepare the OM-SE05xARD boards and i.MX 8M board to run the EdgeLock SE05x Plug & Trust middleware project examples. Follow these steps:

1. Connect the OM-SE05xARD to the i.MX 8M board. The i.MX 8M board does not

come with an Arduino connector, so you have to connect the Arduino shield of the OM-SE05xARD board to the J801_I2C connector of the i.MX 8M board using wires.

Table 3 details the jumper connection

2. Make sure the jumper settings in your OM-SE05xARD board are configured as shown

Note: For more information about the jumper settings, refer to AN12395 (OM- SE05xARD) and AN13016 (OM-SE051ARD) respectively.

4 Software setup

The software setup consists of:

1. Preparing a micro-SD card with the pre-compiled Linux image with the preinstalled Plug & Trust middleware for i.MX 8M board, as described in Section 4.1.

2. Installing the USB to UART Bridge VCOM driver in your laptop, as described in

Section 4.2.

3. Installing TeraTerm terminal application, as described in Section 4.3.

4. Booting the i.MX 8M board, as described in Section 4.4.

4.1 Micro-SD card preparation

To prepare the micro-sd card with the pre-compiled Linux image that includes the Plug & Trust middleware, you need to:

1. Download from NXP website the Plug & Trust middleware SD Card Image. This image contains the Plug & Trust middleware pre-installed with already some examples on a bootable SD Card Image.

Note: In case the image provided by NXP does not suit your use case, you can find the explanation of how to create an card image using Yocto in the Plug & Trust middleware documentation (simw-top/doc/dev-platforms/platform_imx8_linux.html) .

2. Download and install Win32 Disk Imager software. Win32 Disk Imager is a Windows open source program to format SD card images. Instead of Win 32 Disk Imager, you could also use any other software for this operation.

3. Plug your micro-SD card in your laptop.
