Help getting from eval kit to debugable prototype board.

Started by Robert Norman October 8, 2003
Hi,

I need to get a prototype DSP board up and running ASAP and was looking at
the TI320LF2406 and the Motorola 56F803.  Based somewhat on price and GPIO
pinouts I selected the TI part and got the eZDSP system kit thinking
(incorrectly it appears) that I could develop and then move a design to a
prototype board and debug the prototype without additional hardware.  It is
now sinking in that I seem to need to spend  several $1000's  to get
programming and debugging support on my prototype board.

We make extensive use of PIC and Motorola microcontrollers where the $200
kit gets you everything you need to do onboard programming and debugging, so
it appears that that experience led me to make some bad assumptions about
the DSP development.

What is the least expensive way on either TI or Motorola to get a
programmable and debugable DSP board?

Thanks in advance...

Rob




Robert,

You can get a board from motorola for their new DSP56F8322 for $79.
It include a CodeWarrior IDE with 8Kx16 of FREE Compiler with plenty of Free
"Beans" from Processor Expert.
No fancy JTAG Emulator to buy like with TI @ $1000 or $1500.
If you look at the board schematic it's easy to build your own or even use
the small DEMO board to program your target.
In fact every part come with a Serial Bootloader.

With TI, look for "DSK". These are available for several processors, and come with at least assembler and debugger.

I've  done a little more of my homework and found that there is a somewhat
reasonable system from SpectrumDigital at $1300 that appears to do what I
want.  I'm still unclear on what is necessary in the way of upgrades to make
CodeComposer work with my device but it seems doable.  On the other hand,
I'm taking a second look at motorola. Our board designer does not like the
size of the JTAG connnector required for the TI part and I'm wondering if
the project might go better with Motorola.  I've use older versions of
CodeWarrior and like the interface and like the idea that, as Francois
mentioned, there is no need for an expensive (for us) emulator.

Thanks for the responses...
