[U-Boot-Users] sprintf in standalone

Hi! Having problem with the sprintf function, I did the exporting and updating of the files accordantly to the README.standalone. The standalone application seems to compile without error. But once I do the go 40004 I get Alignment Exception and the board resets. If I remove the sprintf line everything works fine. The reason I'm using the sprintf is to modify the setenv which includes a variable. I'm using an MPC83xx. What does the Alignment Exception means?
