Hi, How did you see the revision number? if you are using u-boot you can pause the start and write printenv and enter to see that:
board=am335x board_name=A335BNLT board_rev=00C0 This is in my version. Please tell me so I can check if is the revision, or perhaps is something else in u-boot initialization. For the question Joel asked there is a way: http://dumb-looks-free.blogspot.com.ar/2014/05/beaglebone-black-bbb-revision-serial.html apparently, in the eeprom thorugh i2c it is recorded. But first we must confirm that is a problem from the revisions, since Ragu has the problem in a rev C.
