I tried your command and putting the image at 0xFE000000, I'm not  
sure I see how this works because 0xFE000000 will alias to  
0xFF800000.  However, the reset vector at 0xFFF00100 will alias down  
to 0xFE700100.  So how do you end up with valid code at the reset  
vector if your TEST_BASE is 0xFE000000?
