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

OM-SE05xARD (# jumper - #

pin)

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

in Figure 2:

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.

4. Open Win32 Disk Imager, (1) select from your file system the pre-compiled Linux

image you downloaded from the website, and (2) click on the Write button as shown

in Figure 3.

Note: the SD card image might come in a ZIP package. Make sure to unzip the

package and change the extension to .img before selecting the image file in Win32

Disk Imager.

2. Download the USB to UART Bridge VCOM driver for your processor (either 32 or 64

bits). Install the driver by following the setup wizard until it is finished.

3. Unplug and plug your board.

4. Go to your Device Manager, and check that your board is recognized and assigned

to a port number (COMxx). Write down the assigned port number (COMxx) as it is

needed in the next steps. Your Device Manager should look like Figure 5.

Note: if you see more than one COM port, use the one denoted as Enhanced COM

port.

Figure 5. Check that i.MX 8M board is recognized in Device Manager

4.3 Terminal setup

We need to install a terminal application, for instance TeraTerm, to communicate

and view the serial output of the i.MX 8M board from our laptop. To setup TeraTerm

application:

1. Download TeraTerm and run the installer.

2. Launch TeraTerm, click the Serial option and select from the dropdown list the

Enhanced COM port number assigned to your i.MX 8M board (In this case COM11)

as shown in Figure 6. Click the OK button to confirm the setup. If you cannot see the
