+   Prerequisites:

+     must all be in positions 2-3, that is closest to the edge of the board.
+ 
+   - The uSD card must be formatted as FAT or FAT32, NTFS will not work.
+ 
+   - This test expects a file with the name message.txt to exist in the
+     root folder on the uSD card. The file must be at least 10 bytes in
+     size and the first bytes must be eatest2014
