The NXP analog product development boards provide an easy-to-use platform for evaluating NXP products. The boards support a range of analog, mixed-signal and power solutions. They incorporate monolithic integrated circuits and system-in-package devices that use proven high-volume technology. NXP products offer longer battery life, a smaller form factor, reduced component counts, lower cost, and improved performance in powering state-of-the-art systems.
This page will guide you through the process of setting up and using the RDGD31603PHSEVM board.

Software for RDGD31603PHSEVM 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.
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:

Figure 2. 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.
If a loss of functionality following a board reset, reprogramming, or a corrupted data issue, the microcode may be rewritten per the following steps:
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.
