2.2 Board Description

The KITFS84AUTEVM provides flexibility to play with all the features of the device and make measurements on the main part of the application. The KL25Z MCU installed on the board, combined with the FlexGUI software, allows access to the registers in read and write mode. All regulators are accessible through connectors. Non-user signal, like DC/DC switcher node is mapped on test points. Digital signals (SPI, RSTB, etc.) are accessible through connectors. Pin WAKE1 has a switch to control them (ignition) them. A VBAT switch is available to power the device on or off.

This board can be operated in emulation mode or in OTP mode. In emulation mode, as long as the power is supplied, the board configuration stays valid. The OTP mode uses the fused configuration. The device can be fused three times. In OTP mode, the device always starts with the fused configuration, except if the user wants to overwrite OTP configuration using emulation mode. This board is able to fuse the OTP without any extra tools or board.

Table 1. Evaluation board component descriptions

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

1. Install jumpers for the configuration.

   Table 2. Jumper configuration

   Jumper	Configuration
   J3	connect 1-2 (connect 5.0 V on DBG pin from the USB)

2. Configure switches for the configuration

   Table 3. Switch configuration

   Switch	Configuration
   SW1	middle position (VBAT off)
   SW3	open (OTP programming Off)
   SW2	open (WAKE1)

3. Connect the Windows PC USB port to the KITFS84AUTEVM development board using the provided USB 2.0 cable.

   Set the DC power supply to 12 V and current limit to 1.0 A. With power turned off, attach the DC power supply positive and negative output to KITFS84AUTEVM VBAT Phoenix connector (J1).

4. Turn on the power supply
5. Close SW2

Note: At this step, the product is in debug mode and all regulators are turned off. The user can then power up with OTP configuration or configure the mirror registers before power up. Power up is effective as soon as J3 jumper is removed.

This development kit uses FlexGUI software. FlexGUI software is based on Java JRE.

Preparing the Windows PC workstation consists of three steps.

• Install the appropriate Java SE runtime environment (JRE)
• Install Windows 7 FlexGUI driver
• Install FlexGUI software package

4.1 Install the Java JRE

1. Download Java JRE, available at JRE 8 downloads (8u162 or newer)
2. Open the installer and follow the installation instructions
3. Following the successful installation, restart the computer

4.2 Install Windows 7 FlexGUI Driver

On Windows 7 PCs, a virtual COM port installation is required. Install the Windows 7 FlexGUI driver using the following procedure.

Note: On Windows 10, it is not necessary to install virtual com port as Windows 10 uses a generic COM port driver.

1. Connect the kit to the computer
2. On the Windows PC, open the Device Manager
3. In the Device Manager window, right-click on SECON FLEX GUI SLAVE and then select Properties
4. In the SECON FLEX GUI SLAVE Properties window, click Update Driver
5. In the Update Software Driver window, select Browse my computer for driver software
6. Select Let me pick from a list of device drivers on my computer, and then click Next
7. Select Ports (COM and LPT) from the list, and then click Next
8. Click Have Disk
9. Click Browse
10. In the Locate File window, locate and select fsl_ucwxp and then click Open
11. In the Install from Disk window, click OK
12. If prompted, in the Windows Security window, click Select this driver software anyway
13. Close the window when the installation is complete

The Virtual Com Port appears in the Device Manager window.

4.3 Install FlexGUI Software Package

The FlexGUI software installation only requires extracting the zip file in a desired location.

1. If necessary, install the Java JRE and Windows 7 FlexGUI driver
2. Download the latest FlexGUI (32-bit or 64-bit) version, available at KITFS84AUTEVM

3. Extract all the files to a desired location on your PC

   FlexGUI is started by running the batch file, \bin\flexgui-app-spm.bat.

4.4 Ready to Use

Start embedded application development.
