Well, if CCS says it's truncating to 4 bytes, then I'm not sure what's wrong with the fill definition you're using.
Maybe it's just a syntax issue. You might try:

.sysmem :> DARAM2 PAGE 1 fill = 0xDEAD /* dynamic heap */
.stack :> DARAM2 PAGE 1 fill = 0xBEEF /* system stack */

Also you can try 0xDE and 0xBE (2 bytes) and see if that works.

thanks...
i'll try it...

actually i tried to make a little change on this .cmd-file...
i change the
-stack0x0400 to -stack0x1000
-heap0x0400 to -heap0x1000

could it be affected to the byte size?

thanks...
