You are right.

I looked through the source code:
Because the last "load" write the image into flash, which means the values 
of "entry_address/load_address/load_address_end" are not located in the 
"ram_start - ram_end" region.
So these values are treated as invalid in fis_create() function.

I use the commands below and it works.
"fis create -f 0x80040000 -l 0x000C0000 -n twothreads"
"go 0x80040000"
