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. |

Using DSP56303EVM as JTAG debugger/programmer

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... -- dB --- ukkiwikid <> wrote: > Hi, > I am wanting to use the DSP56303EVM to provide a jtag interface to > our custom board.

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. http://www.newmicros.com/cgi-bin/store/order.cgi?form=prod_detail&part=JTAG-Cabl\ e-14P -david --- In , "ukkiwikid" <burke_scott@h...> wrote: > Hi, > I am wanting to use the DSP56303EVM to provide a jtag interface to > our custom board.

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. Stefan |

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.

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... -- dB --- ukkiwikid <> wrote: > 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. > --- In , "David" <beanfranks@y...> wrote: > > You could do that, but it will be abysmally slow.
