6.1 Installing FlexGUI on your computer
The latest version of FlexGUI supports the GD3100 and GD3160. 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:\flexgui-app-des-gd31xx.exe
.
Installing the device drivers overwrites any previous FlexGUI installation and replaces
it with a current version containing the GD31xx drivers. However, configuration files
(.spi) from the previous version remain intact.
6.2 Configuring the FRDM-KL25Z microcode
Figure 12. 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 13
).
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.
