FRDMGD3160DCMHB evaluation board
5.1.2 Quick start
1. Download and install the latest FlexGUI software (see
)
2. Assemble the FRDMGD3160DCMHB with the translator board and KL25Z on the
3. Check jumper configuration on the evaluation board before powering up, and ensure
that the configuration meets desired use case. See
for alternate SPI configurations. If R50 is closed, FlexGUI displays the same
information for INTBL and INTBH.
4. KL25Z generates the PWM signals for short circuit or double pulse testing. No
external input on J13 (Ext PWM) is required. Check that J4 and J5 use PWM from
MCU (1-2) on translator board.
5. Launch FlexGUI application software on PC, and select the configuration matching
the chosen SPI mode. Connect USB cable from PC to USB KL25Z port on KL25Z
microcontroller board. KL25Z microcontroller is shipped with proper firmware already
6. Supply 12 V DC power to the low-voltage domain of the evaluation board by using
VSUP TP6 and GND TP7.
7. Start FlexGUI communications and check VCCL, VCCH, VEEL, VEEH voltage
levels regarding GNDH and GNDL test points. If VCC voltages are low, adjust R65
potentiometer.
8. PWM, double pulse, and short circuit tests can be generated from the Pulse tab. For
short-circuit testing, PWMHSEL (J11) and PWMLSEL (J10) must be configured to
bypass dead time control (see
).
5.1.3 Normal mode SPI configuration
To access each GD3160 separately (default configuration), check the position of the
following jumpers:
Designator
Signal
Position
J21
MISO
closed
J22
MOSI
closed
J23
CSB
1-2
J24
MISO
1-2
Table 6. Normal mode SPI jumpers configuration
Select the appropriate FlexGUI kit: GD3160 Half Bridge EVBs, and check that the
Feature Set under Advanced Settings is set to standard.
