Here is a C&P from an older usbbdm version 0.5:

**************************************************************************

The readme file here gives you the steps to use BDM on Star Choice box.

*****************
The first time you run usbbdm.exe 0.5 you need:
1. Run the usbbdm.exe again. Go to Tools\Config, on the bottom right select your box type.
The testing has been done on DSR401.
*****************

Test steps with the box. BEGINNER
**** Read *****
You must first familiar with the software and hardware before do any
programming or set NVRAM.

*****************
1. Open the box, plug the cable to the BDM connector to the box. On the back
of the USBBDM, there is a black dot which indicate pin one. Try to match the
pin one on the BDM connector.
If you find the software does not run as you expected, try to flip the
connector.

2.Plug the USB in your PC. Turn the box on. Start the application. You might
need to wait about 2-3 second until everything is setup. (Hear two sound
from your computer speakers).

3. If you want the box run in BDM mode, you must start with command "reset
1".

4. You should see A7 looks like 99999999. If it looks like FFFFFFF7 then
issue "reset 1" one more time.

5. If you still can not see A7 is in 99999999, you need to issue "reset"
followed by "reset 1". The is very unlikely to happen and
if it happens, please send email to [email protected]

6. Issue command "init" will give you access following memory.
a. $000000-$FFFFF
b. $100000-$17FFFF
c. $800000-$81FFFF
d. $A00000-$BFFFFF
7. To program the chip, you need to type command ra7 b10000 to set the stack pointer
to a ram area. Otherwise the program might not work.

My question is, with the lenth suggested, the result should'nt give 1 missing byte at the end of each dump ?
There is a new dll to test ?

$000000-$FFFFF IN here $fffff is the end address not length. So the length will be
end add - start add + 1.
