Getting a board from a distributor like Farnell/Element14/Mouser (add your own distributor) means that chances are high that the default firmware on it is written years from now because the inventory has not been updated, or because boards are still produced with that original firmware (because of testing?).

But when I saw this week in the Freescale forum a user asking for a USB example for that Tower board, I thought that now I could at least use that board to help someone out.
