3.1.1.2.1 Making the Connections in Secondary Power Up Option

Figure 3-1 shows the connections for the secondary power up option.


TIDEP-01036 Connections in Secondary Power Up Option

Figure 3-2 Connections in Secondary Power Up Option

Use the following steps for powering up the reference design through the secondary power up option:

  1. 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
  2. Connect the J1 connector with the bottom 10 pins of the LP-XDS110 using female-to-female connector. See Figure 3-2.
  3. Power up the LP-XDS110 using a USB Type-C® cable
  4. Make sure the SOP lines are in correct configurations while powering up the device. See Section 3.1.1.3 for proper SOP configurations.
  5. nRESET can be issued through the LP-XDS110 reset switch since the J2.6 pin connects to the LP-XDS110 nRST pin
