+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).

Run the following command to initiate U-Boot download:
