2.2 Board Description

The KITVR5510xA0EVM is a development platform built around the VR5510 PMIC as the Device Under Test (DUT). The board allows designers to evaluate various functions of the DUT. Connectors on the board provide the capability of measuring power-related functions such as power, efficiency, loop stability, load transients, etc. Jumpers on the board enable the selection of various capabilities, such as I/O control and switching regulator feedback. The EVM also allows the VR5510 to be set into Debug Mode to facilitate the debugging of faults generated by the device.

The KITVR5510xA0EVM includes NXPs FRDM-K82F development platform board. The FRDM-K82F attaches to the bottom of the board and serves as the communication interface between the KITVR5510xA0EVM and GUI software on the PC.

2.3 Board Components

Overview of the KITVR5510xA0EVM evaluation board.

Install the Software

Unzip the NXP_GUI_PR_4.1.0 into any desired location. Find the NXP_GUI-4.1.0- Setup from the GUI folder inside the package and run it to install the GUI in any desired location.

3.1 Freedom board BOOTLOADER refresh in a Windows 7 system

Note: This procedure does not apply if the board is already programmed.

A pair of RDDRONE-T1 boards are used to connect two standard PCs with RJ45 connectors together over a 2-wire T1 network. The adaptors communicate with each other via T1 and the power is supplied by the PCs over USB cables.

1. Ensure that the boot loader in the GUI package is the latest specified in the link below. If not, download the latest boot loader for the specific MCU (K82F) available at DAPLink bootloader update blog
2. Press the RST push button on the Freedom board and connect the USB cable to the SDA port (J5) on the Freedom board. A new “BOOTLOADER” device appears on the left pane of the File Explorer

   

3. Drag and drop the downloaded file “0244_k20dx_bootloader_update_0x8000.bin” into the BOOTLOADER drive

   Note: Ensure that enough time is allowed for the firmware to be saved in the boot loader.

4. Disconnect and reconnect the USB cable into the SDA port (this time without pressing the RST push button)
5. Drag and drop the file “k20dx_frdmk82f_if_crc_legacy_0x8000.bin” from the package (MCU/K82F_FW folder) into the BOOTLOADER drive.

   Note: Make sure to allow enough time for the firmware to be saved in the Bootloader. The device should change to FRDM_K82FD.

6. Locate the file “nxp-gui-fw-frdmk82f-usb_hid-vr5510_b0_v0.7.3.bin” from the package (MCU/K82F_FW folder) and drag and drop the file into the FRDM_K82FD device
7. The Freedom board firmware is successfully loaded. Disconnect and reconnect the USB cable to the USB port. Open the previously installed NXPGUI. The “Start” button on the top left corner must be activated

3.2 Freedom Board BOOTLOADER Refresh in a Windows 10 System

Note: This procedure does not apply if the board is already programmed.

1. If only the NXPGUI firmware has to be updated, start from Step 4 in Section 3.1 "Freedom board BOOTLOADER refresh in a Windows 7 system". The PC detects FRDM_K82FD. Proceed to Step 6 to load the latest firmware file received from NXP and follow up with Step 7
2. Download the latest bootloader from this location below for the specific MCU (K82F): DAPLink bootloader update blog
3. Disable the storage services: Run services.msc, then double click on the storage service from the list and press the stop button

   

4. Press the RST push button on the Freedom board and connect the USB cable to the SDA port (J5) on the Freedom board. A new “BOOTLOADER” device appears on the left pane of the File explorer
5. Drag and drop the downloaded boot loader file into the BOOTLOADER drive

   Note: Ensure that enough time is allowed for the firmware to be saved in the boot loader.

6. Disconnect and reconnect the USB cable to the SDA port (this time without pressing the RST push button). The drive is changed to “MAINTENANCE”
7. Follow Steps 5-7 from Section 3.1 "Freedom board BOOTLOADER refresh in a Windows 7 system"
8. If only firmware update is required, then repeat Step 1 above
9. Re-enable the services by following Step 2, but now pressing the Start button

Configure the Hardware

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

1. With the USB cable connected to the PC and the USB port in the FRDM-K82F, apply power to the evaluation board:
   • Provide 12 V externally on J92 and J93 (VIN/VBAT, GND)
   • Ensure that the jumpers and switches are configured. Configuring the jumpers and switches is only required if the board comes without a preconfigured jumper set
2. To ensure that the board is properly recognized, press the Reset button on the Freedom board
3. Run the installed NXPGUI application from the start menu or the installation folder
4. A configuration window appears. Select the kit type and the device silicon version and click OK.
5. To enable the connection to the device, click the Start button. When the device is connected properly, the Start button is active and the system is ready for normal or debug operation

   

6. If the NXPGUI does not recognize the FRDM-K82F board or if the Start button does not activate the device, it is possible that the interface is broken. In this case, reprogramming of the FRDM-K82F board can be attempted by following steps in Section 3.1 "Freedom board BOOTLOADER refresh in a Windows 7 system"
