Good.

Bad. You should see something like (PQ2FADS board):

==> loads
## Ready for S-Record download ...

## First Load Addr = 0x00040000
## Last  Load Addr = 0x00050323
## Total Size      = 0x00010324 = 66340 Bytes
## Start Addr      = 0x00040004
=> go 40004 this is a test
## Starting application at 0x00040004 ...
Example expects ABI version 2
Actual U-Boot ABI version 2
Hello World
argc = 5
argv[0] = "40004"
argv[1] = "this"
argv[2] = "is"
argv[3] = "a"
argv[4] = "test"
argv[5] = "<NULL>"
Hit any key to exit ... 

## Application terminated, rc = 0x0

Set a breakpoint and debug. This should not happen.
Check your addresses -- make sure they're valid.

I'm assuming you have RAM at 40000, and u-boot
is running high enough above it (i.e. your stack
stack, heap, etc, are not being corrupted).

imi is for u-boot image files (see mkimage).
