Hi all,
First of all i would like to thank everyone who replied on my post.
The problem was that i used external WDT which prolong the /RESET
duration and caused downloading to fail. Also i had older version of
flash_over_jtag.exe ( new version is available at http://e-
www.motorola.com/cgi-bin/faq.cgi, search for FAQ number 19703.)and
newer version has -w option which will force the tool to wait until
DSP comes out of reset state. When i did this everything worked just
fine.

Hello Ljubisa,

I use flash_over_jtag.exe with Windows95.
I experience the problem, that at power up of the EVM (also our own board
with parallelcom JTAG converter) the first time I run flash_over_jtag it
does not succeed, but the second time it succeed. To solve this problem I
use a batch file, which does this second attempt automatically (see attached
batchfile). I hope this can help you. Maybe the problem is dependant on your
PC operating system? Which Windows version do you use?
If you use an other DSP than 56F807, you must change the batch file
accordingly and also use an other flash.cfg file as delivered with SDK.

I had also the following problem:
When I use DSP56F807EVM or parallelcom-JTAG-converter with their own
delivered parallel cable, they work ok.
However, when I use the parallel cable of the DSP56F805EVM (its little
brother), this cable works with DSP56F805EVM, but does NOT work with
DSP56F807EVM nor with parallelcom-JTAG-converter. When I measured the
difference between those cables with an Ohm-meter, I found no difference, so
I suppose that the difference can be found in cable shield or capacitance. I
did not investigate it in more detail, but used the original cables supplied
with their own boards.

Hello Ljubisa,

I have looked at the schematic diagrams for the DSP56F803EVM, DSP56F805EVM, and
DSP56F807EVM modules. What you are doing with the EVM parallel JTAG command
converter should work OK on all the EVM modules.

When you are using the flash_over_jtag.exe file, did you first run the
UserPort.exe application? This is necessary for the flash_over_jtag.exe
application to work. I have attached the PDF file for the UserPort.exe
application, which explains how to use the UserPort.exe application. When you
run it, the only address range that should be used is the LPT1 printer port
addresses, 378-37F. When we do this, the flash_over_jtag.exe application is
able to successfully connect to the board, enter Debug mode, and download the
program.

The only other thing I can think of is that your computer's printer port is not
fully compatible with the "standard" ECP Printer Port that the
flash_over_jtag.exe file is expecting to use.

Hi Ljubisa,

I have used the flash_over_jtag.exe file to download programs to our 807-based
systems, and it works OK for us here. Perhaps your problem is with the
connection between the JTAG header connector and the DSP chip. Here are the
required connections:

JTAG pin DSP pin
1 <-------> TDI/TCI
2 <-------> Ground
3 <-------> TDO
4 <-------> Ground
5 <-------> TCK
6 <-------> Ground
7 (no connection)
8 (no pin)
9 <-------> /RESET
10 <-------> TMS
11 <-------> +3V3
12 (no connection)
13 (no connection)
14 <-------> /TRST

In our production boards, we use an external WatchDog Timer (WDT) chip, the
MAX6320PUK29CY-T (PDF file was attached to my message "RE: [motoroladsp] 56F807
expected life cycle", sent on Thursday September 5, 2002 at 7:46am). Note that
both /RESET and /TRST must be asserted for a proper power-on reset. /RESET is
asserted either directly from the WDT chip or indirectly using an AND gate.
/TRST can be either tied to ground through a 1.0 kohm resistor, or it can also
get the WDT reset signal through another AND gate. We do NOT tie /TRST directly
to ground, because this would force us to damage the board by cutting a trace
whenever we wanted to do some debugging using the JTAG/OnCE port.

I hope this information helps to solve your problem.

SDK. I am getting following error message when i run this file:

Target chip refused to enter Debug mode!

How can i force DSP to enter Debug mode.
Thanks,
