FRDMGD3160HB8EVM half-bridge evaluation board

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

FRDMGD3160HB8EVM.

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 FRDMGD3160HB8EVM 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 FRDMGD3160HB8EVM 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 13

 to 

Figure 32

 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 13

 allows you to select the target application

board, feature set (standard or daisy chain), target MCU, and USB interface. Leave all

settings as shown.
