KITVR5510xA0EVM Evaluation Kit User Guideline
7.3 Connecting to the KITVR5510xA0EVM board
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 as explained in
. 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, re-
programming of the FRDM-K82F board can be attempted by following steps in
Section 7.1 "Freedom board BOOTLOADER refresh in a Windows 7 system
7.4 Connecting to a reference board with K82F only
Most of the customer reference boards do not have the K82F board as part of the design.
In those cases, a host system and a software/driver package must be available to
interface with the VR5510 PMIC. If they are not available during the development phase,
the following steps can be taken to operate the PMIC in different modes.
1. If the FRDM-K82F board must be programmed or if the firmware must be flashed
again, follow the steps in
Section 7 "Installing and Configuring Software and Tools"
2. The existing NXPGUI firmware provided with the software package (see
"Installing and Configuring Software and Tools"
) can be used to establish the interface
between an external FRDM-K82F board and customer reference board.
3. Follow the setup below or connection between a FRDM-K82F board and the
reference board.
a. Connect the USB cable from a host to the USB port of the FRDM-K82F (J11)
b. Connect wires from the ports of the FRDM-K82F (PTC10 -SCL, PTC11-SDA, and
GND) to the corresponding headers/pins on the reference board.
c. None of the other headers or pins on the FRDM-K82F board have to be
connected.
d. Turn on the reference board by applying power and ensure that the VR5510
powers up with the default OTP settings. Follow the debug entry steps mentioned
Section 8.1 "Operating in debug mode"
.
e. Ensure that the reference board has the right pull-up voltage for the I2C_SCL and
I2C_SDA lines applied through the correct resistor values (2.2 KΩ to VDDIO).
f. If VDDIO or any other pull-up source is not available, then the 3.3 V on the FRDM-
K82F board can be used. In this case, additional wires/connection are required
from pin 8 of J3 (P3V3) of the FRDM-K82F to the reference board through the
appropriate resistors. A jumper should be used to isolate one connection when the
other is used.
