Vi+ Loader Manual 3-9
for 16-Bit Processors
ADSP-219x DSP Loader/Splitter
There are four executable files (streams):
• Application 1 (
app1.dxe
) starts at byte address
0x000000
(ROM)
• Application 2 (
app2.dxe
) appends to Application 1 (ROM)
• Application 3 (
app3.dxe
) starts at
0x020000
(flash page 1)
• Application 4 (
app4.dxe
) starts at
0x030000
(flash page 2)
The task is to create two loader files, one is 16-bit ROM from
0x000000
to
0x01FFFF
and one is 8-bit Flash from
0x020000
to
0x03FFFF
.
There are two different ways to accomplish the task:
1. Use Vi+ Flash Programmer plug-in to burn the Flash. In
this scenario, the real byte address is expected:
elfloader -proc ADSP-2191 -b PROM -width 16 app1.dxe
app2.dxe -pd 0x20000 -p 0x20000 -width8 -o flash.ldr
app3.dxe -pd 0x30000 app4.dxe
!
Since the
-p
value is reset to a zero whenever an
-o
is specified, the
addresses in the Intel hex record starts at zero for
flash.ldr
.
2. Equivalently, invoke the loader twice:
-o
Output file (
.LDR
) for the current and following
.DXE
s (see “-o filename” on
page 3-22 ).
-opmode
Opmode for the current and following .
DXE
s (see “-opmode #” on page 3-22 ).
-p
The Intel hex offset for the current loader file (see “-p address” on page 3-22 ).
-width
Width for the current and following
.DXE
s (see “-width #” on page 3-24 ).
-wait
The number of wait states for this and following
.DXE
s (see “-waits #” on
page 3-24 ).
-clkdivide
Clkdivide for this and following
.DXE
s (see “-clkdivide #” on page 3-21 ).
-maskaddr
Address bits to be masked off for this and following
.DXE
s (see “-maskaddr #” on
page 3-22 ).
