6.4 Importing the example projects in MCUXpresso IDE

There are generally two possible ways to import the A71 project examples in MCUXpresso IDE, depending if we are using the MCUXpresso project files bundled with the A71CL Host Software package or if the installed S DK package already contains the A71CL middleware:

• Importing the A71CL example projects from the installed Kinetis-SDK. This SDK is not available yet and as such this way is not supported yet.

• Importing the A71CL example projects from local drive (included in the A71CL Host Library).

6.4.1 Importing A71CL example projects from local drive

Here the project files bundled with the A71CL Ho st S oftware package can be used. The A71CL Host Software Package can be downloaded from [A71CL_HOST_SW

] [1].

After unpacking the package the example project files are in the subfolder ‘mcux_projects_frdmk64f’ in the case of the FRDM K64F board. It contains one example project:

• frdmk64f_a71cl_baidu: demonstrate basic comm uni cati on and crypto wit h the A71CL and uses the pre-provisioned Baidu-credentials for signing and signature verification

To import a project from file system, click on ‘Im port project(s) from file system…’ in the ‘Quick start Panel’ located in the bottom left. See Fig 19

.

Finally, select all the available example projects, des elect “Copy projects into the workspace” and then click on ‘Finish’.

in case you want to have the same project imported multiple times independently you need to unpack it into distinct directories and import these individually as the code needs to get referenced instead of copied.

Fig 21. Project directory to import

6.5 Terminal setup

A terminal application must be executed from the development PC to interact with the Kinetis board. Any terminal supporting a serial port interface can be used.

In this document, Tera Term is used and can be dow nl oaded from [TERA_TERM

] [2]. The setup wizard will guide the user through the installation. The standard installation can be chosen for this purpose. Once it is finished, Tera Term can be started.

6.6 OpenSDA configuration

OpenSDA is a serial and debug adapter built int o the Kinetis board. It provides a bridge between the development PC and the Kinetis MCU, which can be used for debugging, flash programming and serial communicati on al l over USB.

Note: This section explains how to install the correct OpenSDA bootloader firmware version to the Kinetis FRDM-K64F board. This needs to be done for debugging, flash programming, and serial communication over a single USB connection between a host and an embedded target processor. If this section is not followed caref ull y, it is possible the examples will not be executed.

To configure OpenSDA into the Kinetis FRDM board, an O penSDA bootloader (.bin file) should be downloaded from OpenSDA website [ OPENSDA_FIRMWARE

] [4]. Scroll down the page to section ‘Compatible Evaluation B oards’ and search for the target Kinetis FRDM board. In this case,

Fig 22 depicts the OpenSDA bootloader version

defined for the Kinetis FRDM K64F: version 2.0.

Fig 22. OpenSDA bootloader version for the Kinetis FRDM-K64F

Once the OpenSDA bootloader version is identified, click in the ‘Downloads’, scroll down until ‘J-Link OpenSDA – Generic Firmwares’ appears and do wnload the desired version.

To write the downloaded firmware into the Kineti s FRDM board, the bootloader mode should be enabled. For this, press ‘Reset’ button and, while holding down t he button, connect a USB cable to the debugger port of the K i net i s board (e.g., FRDM K64, Fig 24

).

Fig 24. Enabling bootloader mode

After connecting the USB cable to the Kinetis board, t he green led located inside the yellow square will start blinking and the developm ent PC will show a new drive called ‘BOOTLOADER’. The drive may disappear agai n after ~30 seconds in case there is no interaction, in this case disconnect and connect again with pressing the ‘Reset’ button.

Drag the downloaded firmware directly into the drive (Fig 25

). Once the file is copied inside the ‘BOOTLOADER’ drive the LED will soon start blin k f ast, then unplug the Kinetis board and plug it again. The green led stays on, thus indicating that the OpenSDA bootloader firmware has been configured correctly.
