+Load image from file @var{filename} to target memory offset by @var{address} from its load address. 
 The file format may optionally be specified

+(@option{bin}, @option{ihex}, or @option{elf}).
+In addition the following arguments may be specifed:
+@var{min_addr} - ignore data below @var{min_addr} (this is w.r.t. to the target's load address + @var{address})
+@var{max_length} - maximum number of bytes to load.

+    # Load data from fname filename at foffset offset to
+    # target at address. Load at most length bytes.
+    load_image $fname [expr $address - $foffset] bin $address $length
