Using DSP56303EVM as JTAG debugger/programmer

Started by ukkiwikid October 10, 2003
Hi,
I am wanting to use the DSP56303EVM to provide a jtag interface to
our custom board. If I am correct this should provide me with a
serial interface to the on board command converter then jtag to our
56311.

If any body has done this or sees any problem with it then please let
me know?

Cheers,

Scott.



Scott,

It can be done, but it requires hardware modifications to the 56303EVM.
You will need to lift the JTAG/OnCE pins on the 56303. IMHO it's much
easier to spend the $150 or so on a Parallel Port Command Converter and
use the free Suite56 tools. The Suite56 tools have many more features
compared to the Domain Technologies tools and the PP command converter
is much faster...

You could do that, but it will be abysmally slow. BTW, the code for
the HC705K1 on the EVM is available for the asking at Motorola's DSP
tech support, so you can burn your own micro to put on your board
directly.

For $25, you can try the New Micros' 14-pin command converter. It was
designed and built for the 56800/E devices, but it should work for the
56300s as well. (Please note, I've not personally tried it - but have
just ordered one for myself to try.) For the $25, if it works, you
get to use the Motorola Suite56 tools. The parallel interface is also
considerably much faster than the serial EVM command converter.

know? I think there are at least two versions of the DSP56303 EVM, and only
the very first can be used as a JTAG interface. I have one here in the
office, and did this years ago:

- remove all jumpers that connect JTAG to on-board DSP56303
- build a cable that fits one side onto the now blank jumper pins
and on the other side to your own DSP hardware. Unfortunately
you have to do this wire by wire, just multiwire flat cable
does not work.

Thanks,

Can anyone tell me if the Tasking debugger (Crossview Pro) is capable
of interfacing with the suite56 tools or the motorola parallel
command converter.

Cheers, Scott.

The Tasking tools should work with the Parallel Port Command Converter
(or similar device), but they aren't going to work with the serial
debugger. The serial debugger built into the 56303EVM is specific to
Domain Technologies...
