6 Installation and use of software tools
Software for FRDMGD3162HBIEVM is distributed with the FlexGUI tool (available on
NXP.com). Necessary firmware comes pre-installed on the FRDM-KL25Z with the kit.
Even if the user intends to test with other software or PWM, it is recommended to install
this software as a backup or to help debugging.
6.1 Installing FlexGUI on your computer
The latest version of FlexGUI supports the GD3100, GD3160, and GD3162. It is
designed to run on any Windows 10 or Windows 8 based operating system. To install the
software, do the following:
1. Go to www.nxp.com/FlexGUI and click Download.
2. When the FlexGUI software page appears, click Download and select the version
associated with your PC operating system.
3. FlexGUI wizard creates a shortcut, an NXP FlexGUI icon appears on the desktop. By
default, the FlexGUI executable file is installed at C:\NXP_GD31xx_GUI-x.x.x.msi.
Installing the device drivers overwrites any previous FlexGUI installation and replaces
it with a current version containing the GD31xx drivers. However, configuration files
from the previous version remain intact.

6.2 Configuring the FRDM-KL25Z microcode
Figure 13. FRDM-KL25Z setup and interface
By default, the FRDM-KL25Z delivered with this kit is preprogrammed with the current
and most up-to-date firmware available for the kit.
A way to check quickly that the microcode is programmed and the board is functioning
properly, is to plug the KL25Z into the computer, open FlexGUI, and verify that the
software version at the bottom is 6.4 or later (see Figure 14).
If a loss of functionality following a board reset, reprogramming, or a corrupted data
issue, the microcode may be rewritten per the following steps:
1. To clear the memory and place the board in boot loader mode, hold down the reset
button while plugging a USB cable into the OpenSDA USB port.
2. Verify that the board appears as a BOOTLOADER device and continue with step 3. If
the board appears as KL25Z, you may go to step 6.
3. Download the Firmware Apps .zip archive from the PEmicro OpenSDA webpage
(http://www.pemicro.com/opensda/). Validate your email address to access the files.
4. Find the most recent MDS-DEBUG-FRDM-KL25Z_Pemicro_v118.SDA and
copy/drag-and-drop into the BOOTLOADER device.
5. Reboot the board by unplugging and replugging the connection to the OpenSDA
port. Verify now that the device appears as a KL25Z device to continue.
6. Locate the most recent KL25Z firmware; which is distributed as part of the FlexGUI
package.
a. From the FlexGUI install directory or zip file, downloaded, find the firmware bin
file “flexgui-fw-KL25Z_usb_hid_gd31xx-Vx.x.x.bin”.
b. This .bin file is a product/family-specific configuration file for FRDM-KL25Z
containing the pin definitions, SPI/PWM generation code, and pin mapping
assignments necessary to interface with the translator board as part of
FRDMGD3162HBIEVM.

NXP Semiconductors UM11729
FRDMGD3162HBIEVM half-bridge evaluation board
7. With the KL25Z still plugged through the OpenSDA port, copy/drag-and-drop the .bin
file into the KL25Z device memory. Once done, disconnect the USB for OpenSDA
port and plug into the other USB port, labeled KL25Z.
a. The device may not appear as a distinct device to the computer while connected
through the KL25Z USB port, this is normal.
8. The FRDM-KL25Z board is now fully set up to work with FRDMGD3162HBIEVM and
the FlexGUI.
a. There is no software stored or present on either the driver or translator boards,
only on the FRDM-KL25Z MCU board.
All uploaded firmware is stored in non-volatile memory until the reset button is hit on the
FRDM-KL25Z. There is no need to repeat this process upon every power up, and there is
no loss of data associated with a single unplug event.
6.3 Using the FlexGUI
The FlexGUI is available from http://www.nxp.com/FlexGUI as an evaluation tool
demonstrating GD31xx-specific functionality, configuration, and fault reporting. FlexGUI
also includes basic capacity for the FRDMGD3162HBIEVM to control an IGBT or SiC
module, enabling double pulse or short-circuit testing.
SPI messages can be realized graphically or in hexadecimal format. CSB is selectable to
address one or both GD31xx on the board via daisy chain. See Figure 14 to Figure 34 for
FlexGUI for GD31xx internal register read and write access.
Starting FlexGUI for GD31xx
•FlexGUI install program (C:\NXP_GD31xx_GUI-x.x.x.msi)
•Download FlexGUI and run the install program on your PC.
•When you start the application, Figure 14 allows you to select the target application
board, feature set (standard or daisy chain), target MCU, and USB interface. Leave all
settings as shown.
