Emulator/programmer for TI TMS320F2812 DSP.
Roberto Waltman
Looking for recommendations on a JTAG programmer / emulator for a
product under development.
The target processor is a TI TMS320F2812 DSP, and the software is
written using TI's Code Composer's Studio V2.2
Thanks,
Roberto Waltman.

We've been using Spectrum Digital XDS510PP+ on a large project for
quite some time now. This is the emulator that TI sells in packaged
kits with Code Composer Studio.
Early on we had some of them develop problems. When we sent them back
to Spectrum Digital, they always fixed and returned them quickly, and
free, but we were starting to get seriously concerned about their
reliability until they told us what the problem was.
The connector on the end of the ribbon connector that plugs into the
JTAG header on the board does not have any strain relief, and the way
we need to twist it to get it to plug into some of our boards in the
actual system was breaking the wires.
Since we took off the original connectors and put on our own, with
strain relief, we haven't had any problems at all with any of the ones
we have (we have several) in more than a year.
In addition to development, there is a free add-in for Code Composer
Studio that allows programming flash from the CCS IDE.
This model requires a parallel port, which is something we still have
on all our laptops that we use for debugging. No problem through 25
feet of parallel cable.
They also have a USB version of the same emulator, which is more
expensive, but we haven't tried it so I can't comment.
If you are going to use this emulator there is something you might be
able to do with your PC board layout that will make life easier. If
you have +5 volt supply on your board, route this to the Vcc pin on
the JTAG connector instead of the +3.3 volt supply. The emulator can
run off your board's power if you give it five volts on that pin. If
you give it 3.3 volts, you need to plug the wall wart power supply
into the emulator.
