The KITPF7100FRDMEVM can use the NXPGUI for any of the PF7100 devices. Prior to the installation of the NXPGUI software and performing device firmware updates (if needed), download and unzip the NXP_GUI_PR_version.zip file to any desired location.

Open and run the NXP_GUI_version_Setup.exe file from the unzipped package. This installs the NXPGUI software in the system. Install it in a local destination folder.

The installation package is available at PF7100 Evaluation Board.

3.1 Updating the PF7100 NXPGUI Firmware

The FRDM-KL25Z FRDM board is used to operate as a communication bridge to interface the NXPGUI with the PMIC and other I²C devices. The firmware is organized in three levels:

  1. At first level, the SDA uses the BOOTLOADER to operate as the main path to flash the functional code of the SDA processor. The BOOTLOADER is preprogrammed on the FRDM-KL25Z FRDM boards and cannot be reflashed to avoid permanent damage to the FRDM board
  2. At second level, the SDA provides a firmware loader for quick drag and drop update of the KL25Z MCU firmware
  3. At the third level, the KL25Z MCU provides the NXPGUI firmware in charge of converting the USB communication into MCU instructions to control digital I/Os, as well as I²C communication to the PMIC

If the FRDM-KL25Z is not loaded with the correct firmware to support a future software upgrade, the firmware can be updated in a few simple steps.

Note: The following firmware updates are optional and can be skipped if the firmware is up-to-date.

3.2 Flashing the FRDM-KL25Z Firmware Loader

  • Press the push button on the FRDM board 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. This step is optional and should be performed only if the FRDM_KL25Z driver does not appear when the SDA port is connected
  • Drag and drop the file MSD-DEBUG-FRDM-KL25Z_Pemicro_v118.SDA into the BOOTLOADER drive. File should be located in the KL25Z firmware folder
  • Disconnect and reconnect the USB cable into the SDA port (this time without pressing the push button). A new device called FRDM_KL25Z is installed on the PC

3.3 Flashing the NXPGUI Firmware

If a new software or silicon release requires a firmware update on the FRDM-KL25Z FRDM board, use the following steps to upgrade or downgrade the firmware of the FRDM board as needed. Note that this procedure is needed only to update the firmware and may be skipped if no change is needed.

  • Connect the USB cable in the SDA port (without holding the push button). The PC installs a new device called FRDM_KL25Z
  • Locate the ".bin" NXPGUI driver to be installed, for example nxp-gui-fw-frdmkl25z-usb_hid-pf7100_version.bin and drag and drop the file into the FRDM_KL25Z driver
  • FRDM board firmware is successfully loaded

4.1 Overview

  1. Connect the USB cable from the PC to the USB port on the FRDM board and apply VIN to the evaluation board
    • Provide external VIN between 3.0 V to 5.5 V on J10 (VIN) and J4 (GND)
    • Short jumper J7 1-2 to provide 5.0 V Vin from FRDM board (use this mode of operation for functional demonstration only, no regulation loading allowed in this mode)
  2. Open the NXPGUI application from the installation folder or from the Start menu to start the application
  3. The NXPGUI launcher is displayed with a list of possible configurations to load the NXPGUI. Select the appropriate option for device and silicon revision to be used. If the device revision populated on the KITPF7100FRDMEVM is not available in the list, contact your NXP representative to obtain the latest software update suitable for your device. Click OK to launch the NXPGUI
  4. Press Reset on the FRDM board, only if the board is not properly recognized The USB-HID connection automatically searches for the KITPF7100FRDMEVM if a valid board is connected. This is displayed by the active Start button on the top-left corner of the NXPGUI, then click Start to create a connection. The Start button changes to Stop after clicking. The device status can be read from the bottom-left corner of the NXPGUI. Once the device is connected, the system is ready for hardwire or TBB operation as desired.
