Softdevice example doesn't start when powered by other source than MCU interface.

Hi,

Recently I receive the "nRF52840-Preview-DK" and I download the "nRF5 SDK v14.0.0". I try some example with Keil and all of them works well when I use the MCU interface. But when I try to powered the board with other source than the MCU interface only examples that do not include softdevice works. Examples with softdevice seems to doesn't start. I have the same problem if I copy directly the hex file on the JLink storage manager.

If I define other pins on nRF52840 to drive Uart signal (TxD, RxD), which are not link to the Analog Switch FSA2466, it works with all power supply configuration.
