Power-On Procedure
Place the SKEVM boot switch selectors (SW1, SW2) into selected boot mode. Example boot-modes for SD card and no-boot are shown below.
Connect your boot media (if applicable).
Attach the PD capable USB Type-C cable to the SKEVM Type-C (J11 or J13) Connector.
Connect the other end of the Type-C cable to the source, either AC Power Adapter, or Type C source device (such as a Laptop computer).
Visually inspect that either LD10 or LD12 LED are illuminated.
XDS110 JTAG and UART debug console output are routed to micro-USB ports J16 and J15, respectively.
