Figure 3-1 shows the connections for the primary power up option.
Use the following steps for powering
up the reference design through the primary power up option:
- Connect the J2.7(VBAT) pin to a
12V DC supply
- Connect the GND pin of the DC
supply to the GND pin of the reference design or to the GND pin of LP-XDS110 to
provide the common GND across the setup
- Put a jumper on the 2-3 pin of
the P9 connector of the LP-XDS110 to make sure the 3.3V IO supply is provided by
the reference design to the LP-XDS110
- Connect the J1 connector with the
bottom 10 pins of the LP-XDS110 using a female-to-female connector. See Figure 3-1.
- Power up the LP-XDS110 using a
USB Type-C® cable
- Make sure the SOP lines are in
correct configurations while powering up the device. See Section 3.1.1.3 for proper SOP configurations.
- nRESET can be issued through the
LP-XDS110 reset switch since the J2.6 pin connects to the LP-XDS110 nRST
pin
