+Boot from UART:
+---------------
+
+Connect the on-board micro-USB (CF Pro: CON11, CF Base: CON5)
+to your host.
+
+Set the SW1 DIP switches to UART boot (0: OFF, 1: ON):
+
+ ClearFog Base: 01001
+ ClearFog Pro: 11110
+
+Run the following command to initiate U-Boot download:
+
+ ./tools/kwboot -b u-boot-spl.kwb /dev/ttyUSBX
+
+Use the correct UART device node for /dev/ttyUSBX.
+
+When download finishes start your favorite terminal emulator
+on /dev/ttyUSBX.
