The addresses in your s-record file indicate it should be loaded to 
0xffffffff, which isn't right. Check your s-record file, and how it was 
built, and particularly how the memory map was linked.

Or more relevantly, if it isn't an s-record file, either convert it to one 
or choose the appropriate flag to "load" to tell redboot what format it is!
