Hot U3 and U6 on DA14585 BASIC Kit

In the DA14585 BASIC kit, when the power is set to come from the 3v3 of the USB through the U3 LDO and pressing the reset button, both U3 and U6 grow extremely hot. This is due to the shorting of the output of U6 to the power rail (hence U3). Some isolation is required, like a diode to protect the output of the U6.
