1. Get Started
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 KITFS26AEEVM evaluation board.

2.2 Board Description
The FS26 family can be evaluated with this board as it is populated with a superset part. The FS26xx part soldered on the board can be fused one time or it is possible to test as many configurations as needed in Emulation mode.
This board was designed to sustain up to 2.0 A total on VPRE. Layout is done using six layer PCB stack up. Set initial current limitation of 1 A.

3. Install Software
The programming/evaluation boards are always delivered with the GUI firmware already flashed. If the MCU firmware is already flashed, this section can be ignored. If it is specified that the firmware must be updated, or if it is malfunctioning, follow these instructions.
3.1 Flashing or Updating the GUI Firmware
The KITFS26AEEVM is delivered with the GUI firmware flashed. If MCU firmware is flashed, ignore this section. If it is specified to update the firmware or it is malfunctioning, follow the instructions below.
3.2 Flashing FRDM Board Firmware for Windows 7/10
If BOOTLOADER is already loaded in the FRDM Board, steps 1 to 3 are not required. Start from step 4.
-
Disable the Storage Service and Windows Search: Run Services, double click, and stop them as shown below
Steps 2 and 3 are not required if BOOTLOADER is already loaded in the FRDM board -
Press the RST push-button and connect the USB cable into the SDA port on the FRDM board.
A new “BOOTLOADER” device should appear on the left pane of the File explorer -
Drag and drop the file “MSD-DEBUG-FRDM-KL25Z_Pemicro_v118.SDA” to the BOOTLOADER drive.
-
Disconnect and reconnect the USB cable into the SDA port
This time without pressing the RST push-button, FRDM_KL25Z device should appear on the left pane of the File explorer as pictured below
-
Locate the file “nxp-gui-fw-frdmkl25z-usb_hid-fs2630_vX.Y.bin” from the package and drag and drop the file into the FRDM_KL25Z device
- FRDM board Firmware is successfully loaded. Disconnect and reconnect the USB cable into the KL25Z USB port
3.3 Installing GUI Software Package
To install the FS26 NXP GUI, download or obtain the NXP GUI package, unzip 1- NXP_GUI_Setup folder:
Then, double-click NXP_GUI_version-Setup.exe and follow the instructions.
To install the application on Windows PC, proceed with the following pop-up windows:
Select the following options before completing the installation of the setup:
- Run NXP_GUI
- Show Readme
Select Finish to complete the installation.
When the installation is finished, you can find the application by searching for NXPGUI in the windows search bar. Click to launch.
