[DSP-10] DSP-10 software loading problem

[Ton Bouw]

Hi David,

Congrats on the progress so far. I wonder if you try to run in a DOS box or
have restarted MS-DOS from Windows.
You MUST start the PC in DOS mode (press F8) dureing start-up to enable
starting in DOS.

I hope this will help you further.

73's,

Ton, PA0TBR

Hi All

Hardware:
This side is progressing well - the Box drilling is completed and the DSP-10
PCB in a fairly advanced state of assembly with the last lot of  of SMD's
ordered and scheduled to arrive 11 Jan 2003.
                                    --------------------------------

Software (part1):
This is where I have a few problems:

I have got to checking out the AD-2181 EZKit-lite (EPROM REV.1.0) - it works
OK with the Demo program "DTMF" after building it within the VisualDSP++
environment, but not having much luck with getting the UHF3 running in
hardware=0 mode.  Does the Red light go out when the UHF3 Program has loaded
and running?

My batch file is as follows:

SET TZ=GMT0
EZFAST 1 UHF3.EXE G
UHFA 1

There is a snag when loading the prog via EZFAST  loader, it hits a problem
(or two) and shows the following screen (s):

****************************************************************************
**
Moon and Sun data unavailable, needs 'SET TZ=PST8', etc.
Computer time=Thu Jan 02 15:40:11 2003
big_area_ptr2 = 5BCA:0004
power10[]     =6800:0004
pwrdat[]       =6881:0004
dnorm[]       =6983:0004
lt_dnorm     =6A85:0004
lt_pwrdat    =6B06:0004
pd16[]        =6B87:0004
Heap is verified

Downloading DSP pointers...
Error in obtaining DSP pointer table. Filter design

Graphics driver= 9, Mode 2

Graphics is EGAVGA, Mode 2, 640 x 480

Hit 'Enter' (with Scroll Lock off) to proceed.
Any other key will give 'key ident' for uhfa_kbd_h.
Exit program with Scroll Lock Alt F4.  See Readme
file for list of keyboard commands. No mouse is used.
****************************************************************************

Following from this the Blue screen comes up and the PC program UHFA.exe
seems to run OK but there is no evidence of any communication with the DSP
board. - in fact the red light on the board has continued to flash since it
was first reset (prior to loading).

I reached the conclusion that for some reason the UHF3 program has not
loaded and is not running.
        `                                ------------------------

Software (Part 2)
I therefore decided to try loading via the VisualDSP++ (vers 2) window.
This didn't work either.  The elf loader clearly expected a *.dxe file.
Rather than try to start a new project and build a new file I tried to load
the available *.exe file.  But the system didn't like that and it put out a
message:

Loading "c:\DSP10\uhf3.exe"
Error getting elf descriptor of file "c:\DSP10\uhf3.exe"
Check for non elf or zero byte file
Load failed

It would appear that the later release of the VisualDSP++ works with
slightly different files than the previous one and I will probably have to
build a new *.dxe file?
                                        ------------------------

Rather than read the large pile of paper I seem to have accumulated once
again,  I wondered if any of you more experienced builders could tell me
what I am doing wrong?
