9.2 Board revision
Important note about owners of revision B of the board: if you are one of the first owners of
iMX233-OLinuXino-Micro and you experience random hang-ups (Kernel oops, Kernel panic)
it is recommended to unsolder/remove R17 (check the schematic or the board file to locate it
easier). Removing R17 fixes the random lock-up.
This problem has been fixed in revision B1 of the board.
