2.2 Board Description

The KITFS85FRDMEVM 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. Nonuser signal, like DC/DC switcher node is mapped on test points. Digital signals (SPI, I2C, RSTB, etc.) are accessible through connectors. WAKE1 pin has a switch to control (Ignition) them. A VBAT switch is available to power ON or OFF the device.

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 boards.

2.3 Board Components

Table 1. Evaluation Board Components Description.

3.1 Configure the Hardware

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

1. Install jumpers for the configuration

   Table 2. Jumper configuration.

   Jumper	Configuration
   J9	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
   SW3	Middle position (VBAT OFF)
   SW1	Open (OTP programming OFF)
   SW2	Open (WAKE1)

3. Connect the Windows PC USB port to the KITFS85FRDMEVM development board using the provided USB 2.0 cable
4. 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 KITFS85FRDMEVM VBAT Phoenix connector (J1)
5. Turn ON the power supply
6. 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 the J9 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:

1. Install the appropriate Java SE Runtime Environment (JRE)
2. Install the Windows 7 FlexGUI driver
3. Install the FlexGUI software package

4.1 Install the Java JRE

1. Download Java JRE (Java SE Runtime Environment), available at Java 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 a Virtual COM port as Windows 10 uses a generic COM port driver.

1. Connect the kit to the computer as described in Section 3 "Configure Hardware"
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 Driver Software" 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

14. In the "Virtual Com Port Properties" window, verify that the device is working properly and then click Close


The Virtual COM Port appears in the "Device Manager" window

4.3 Install FlexGUI software package

The FlexGUI software installation requires only 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 KITFS85FRDMEVM
3. Extract all the files to a desired location on your PC

FlexGUI is started by running the batch file: \bin\flexgui-app-fs85.bat.
