To use an external 5-V source to power the EVM, connect the 5-V and GND lines of the supply to the 5V and GND pins of the external power header (J11) or to the 5V pin on the BoosterPack header (J3). Connect the onboard 3.3-V LDO (U5) to the 3.3-V power rail by populating the jumper on JP8 to connect the output of the LDO to the 3.3-V power rail. Figure 2 shows the location for JP8.
