[U-Boot-Users] sprintf in standalone

[U-Boot-Users] sprintf in standalone

[trigga]

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?

Maybe 40004 is not the correct entry point. The entry point may
change after modifying the standalone application, see:

I checked the entry point by using nm, and found it set to 40004. So it's not
that.
