The standalone application needs to be linked to a static address.  If
you look into the Makefile in examples, you'll see that for your board
"LOAD_ADDR = 0xc100000", i.e. that's where the binary _can_ run.  If
this is not RAM on your system, adjust the makefile, rebuild the app,
load it at that address and then run from there.
retry.

Cheers
