[DSP-10] software query

[Bob Larkin]

Let me take a try at this, as I think Lyle is really busy with non-ham 
stuff. Yes, Dale, there are a lot of pieces to this now!

I will chop up your email...

The 2185 has virtually no software, only a boot loader that can load a 32 
word program from the so-called Byte Memory, which for the DSPx is the 
Flash Memory. See the 2185 data sheets, and the "ADSP-2100  Family User's 
Manual" for details.

The 39VF040 can be thought of as 8 Banks of 64K bytes, 0 to 7 (An aside: 
the 2185 supports 16K chunks, but the 64 K does everything we are likely to 
need).

Flash Bank 0, from Lyle, has a version D.1 monitor, compatible with the 
EZ-Kit Lite Monitor Commands (like $$$) and also allows running from Bank 1 
by either the $BF command or a reset with JP1 in place.

Flash Bank 1 depends on the vintage. The latest have UHF3 for the DSP-10. 
It is easy (harmless) to change. See the FL1.BAT PC DOS files available 
from my web site
http://www.proaxis.com/~boblark/dsp10.htm at "DSPx Flash Loading Program."

In general, the DSP-10 is not compatible with XP. Use the true DOS.

Flash Bank 0 needs to be treated with care. Number 1 rule: If JP2 is out, 
everything is safe. The basic program for erasing/writing to Flash is 
FLASHUTL from Lyle. This will not erase/write Bank 0 if JP2 is out (not 
jumpered). Assuming that you have version D.1 of the monitor in the Flash 
Bank 0, you can just leave JP2 open!

To determine the monitor version, use an ASCII terminal, 9600 8N1, and hit 
reset on the KDSP10. Alternatively, use my PC DOS program XF_TERM1 from my 
web page, that is very specific to identifying the version from the sign-on 
banner, and does not require a terminal program.

If at some time, there is a need to update Bank 0, it can be done (see FL0.BAT
"DSPx Flash Monitor Loading Program" ) at my web site. If you have D.1, you 
don't need to even look at this.

>3) Which tools and steps are needed to put a piece of code, like one of the

The monitor in Flash Bank 0 runs at reset. It supports the loading and 
starting of any 218x program in the DSP. The loader is EZLD for DOS or 
either EZLOAD or the ADI furnished program for Windows. EZFAST loader can 
be used also with DOS, but only at 9600 baud. The D.1 monitor does not 
support 56K or 115K rates.

It is useful to make the A/D and D/A ins and outs available for external 
use. KD7TS posted info on this:

Sounds GREAT!  Jump in and let us know what you come up with!
