Please use the correct device node for your setup instead
of "/dev/sdX" here!
+Boot selection:
+---------------
+
+Before powering up the board, boot selection should be done via the SW1 dip
+switch (0: OFF, 1: ON):
+
+ - SPI: 00010
+ - SD/eMMC: 00111
+ - M.2 SSD: 11100
+ - UART: 01001 [1]
+
+[1]: According to SolidRun's manual, 11110 should be used for UART booting on
+ the ClearFog 'Pro' variant.
+ However, this doesn't work (anymore) at least on Rev. 2.1 (but '01001' as
+ mentionend for the 'Base' variant does).

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
+Set the SW1 DIP switches to UART boot (see above).
