====== MBa335x DIP switch settings ======

===== Boot Device Selection (S2) =====

To select the desired boot order set the DIP switch S2 accordingly.




The following boot sequences of the AM335x can be selected by the DIP switch S2 on the MBa335x.
Each boot device in a sequence will be searched until a valid boot image is found.
