[DSP-10] DSP-10 software loading problem

[David Wrigley]

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=3D0 mode.  Does the Red light go out when the UHF3 =
Program has loaded and running?

My batch file is as follows:

SET TZ=3DGMT0
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=3DPST8', etc.

Heap is verified

Downloading DSP pointers...
Error in obtaining DSP pointer table. Filter design
will not be available. Hit Enter to continue

Graphics driver=3D 9, Mode 2
Graphresult=3D 0,   Hit 'Enter' to proceed

Graphics is EGAVGA, Mode 2, 640 x 480
Bottom image size (170 lines worth) is 43526 bytes

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?
