Purchase your KITFS26AEEVM | FS26 Safety SBC Evaluation Board

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.

Note: Make sure to allow enough time for the firmware to be saved in the BOOTLOADER
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

Note: Make sure to allow enough time for the firmware to be saved.
FRDM board Firmware is successfully loaded. Disconnect and reconnect the USB cable into the KL25Z USB port

4.1 Configure the Hardware

GS-KITFS26AEEVM-IMG11

To configure the hardware and workstation, complete the following procedure:

With SW1 in middle position, set DC power supply to 12 V and current limit to 1.0 A. Attach the DC power supply positive and negative output to KITFS26AEEVM VBAT Phoenix connector (J20). Or connect 12 V power supply to VBAT Jack (J21).

Table 1. VBAT Phoenix connector (J20)

Schematic label	Signal name	Description
J20-1	VBAT	Battery voltage supply input
J20-2	GND	Ground

Table 2. VBAT three position connector (SW1)

Schematic label	Signal name	Description
SW1 pin 2-3	VBAT Phoenix	Board supplied by Phoenix connector
SW1 pin 2 (middle position)	VBAT	Board not supplied
SW1 pin 2-1	VBAT jack	Board supplied by Jack connector

Connect the Windows PC USB port to the KL25Z USB side of the FRDM board included in the kit, using the provided USB 2.0 cable.
Turn on SW6 to apply V_DBG to the DEBUG pin or SW7 to apply V_OTP
Turn on the power supply
Close SW1

Note: At this step, the product is either in Debug mode, and all regulators are turned off, or in OTP emulation mode. In the latter, the user can then power up with a preloaded OTP configuration or manually configure the mirror registers before powering up (the power up is effective as soon as SW7 is turned off).
