Re: Jtag Flash Loader

Started by Graeme Fisher February 11, 2003
Hi,

Does anyone know what modifications I need to make to the
flash_over_jtag config/source files to get it to work on the DSP56303EVM
on its JTAG port. I have all the necessary harware etc. Just need
software advice on how to do this

Regards
Graeme




Graeme,

I could be wrong, but I believe you might be looking in the wrong
place for what you need. The flash_over_jtag utility is specifically
designed for the DSP568xx family and NOT the DSP563xx family. I have
seen several posts where you are confusing the tools and features for
these families but they do not overlap very much.

Metrowerks offers the Suite56 Tools which you can download for free
at:

http://www.metrowerks.com/MW/Develop/Embedded/suite56.htm

These tools include a command line based and GUI-based debugger that
you can use to download code to the DSP56303. The flash_over_jtag
tools is designed to program the internal Flash and RAM that is on
most of the DSP56F8xx parts. The DSP56303 does not have any internal
flash, but instead some bootflash ROM. The flash algorithms that are
used to program the DSP56F8xx devices will not overlap and correspond
to the DSP563xx families as far as I know.

If you already know this but still want to try and modify the tool to
get it to work, then good luck.....but it's not going to be a trivial
task from what I can tell. My recommendation would be to use the
Suite56 debugger (or another set of tools designed for the DSP563xx
family such as Tasking) to program the device.

Regards,
John

Graeme,

The flash_over_jtag software was designed to program the internal flash
of a 56F80x device. It has nothing in common with programming the flash
on a 563xxEVM. There is software designed for this purpose though.
(I'll send it to you directly so everyone in the group doesn't have to
download it)...
