TMS320F2812 Flash Programmer and Debugger?

Other Parts Discussed in Thread: TMDSDOCK28335

Hi there,

I am new to the DSP world, I have experience with 8 bits MCU (Freescale) and I want to start with DSP.

I want to build my own circuit, I don't know where to start! so I have some question:

1- How to do flash programming to this DSP, I mean the Hardware interface (USB or other), do you have any link as reference design (like JTAG) but open source or free (I am a hobbyist!!!!)

2- Wich debugger is the right one for this DSP (CCS or there is something else)

3- I have an evaluation board ez430-F2500 with the interface JTAG (I thing it is a Spi-By-Wire interface), is that interface good enough to program theh DSP?

Any feedback will be very appreciated...

Thanks to all..

    Hi Steve,

    Thanks for your reply. It looks very interesting. What about the the ez430-F2500 interface? It does work like JTAG emulator? or I really need the Xds100 (minimally) to interface the TMS?..

    Thanks for any advice.

    EZ430 won't work with 28x. Need the XDS100 to do that.

    Thanks for your help. I will try to do my own programmer (XDS100) ;).

    Fidellyo,

           I would take a look at the hardware schematics for the F2808 Experimenter's Kit docking station, as it has onboard USB JTAG XDS100 emulation. These are available for free from www.ti.com/c2000tools and can be installed with the Baseline Software installer. Also, see my post on the "Dual RS232 Fix" for information on how to program the FDTI chip for the Experimenter's Kit hardware.

    Hi charlie,

    Thanks for your advice, I found the TMDX28027USB controlSTICK USB evaluation tool extremely interesting but I have one question:

    when I looked to the schematic and the pinOut table I didn't see any of the JTAG pins populated!! (So I think it is not intend to program other devices :((((  )

    Can I do a sort of pin hack to connect the JTAG pins emulator to an external device? (such as the F2812!) or the software is locked to the DSC included in the experimenter kit!!! ..

     

    Have a good day!

    Fidellyo,

          What I meant was that you could put the XDS100 onto your F2812 board that you are desiging. In other words you could easily copy our design for the XDS100 emulator and then wire it up to the F2812's JTAG pins, just like the XDS100 emulator is wired up to the F28027 on the Piccolo controlSTICK. You could then follow the instructions on my post about the "Dual RS232 Fix" to program the XDS100 emulator. I would recommend using the XDS100 design in the F2808 Experimenter's Kit baseboard, as it is slightly more robust than the controlSTICK's. You can also use the XDS100 FTDI chip as an SCI(serial) to USB bridge.

    You could also just purchase a Blackhawk USB emulator, TMDSEMU2000U from www.ti.com/c2000tools. (search for it, it is at the bottom of the page)

    What sort of application are you using the F2812 in? Have you considered the F28235? It is less expensive than the F2812 and has a much better ADC. If you need an EVM the F28235 is completely compatible with the F28335 (the floating point version of the F28235) and you could purchase the F28335 Experimenter's Kit (TMDSDOCK28335) and then incorporate the controlCARD onto your initial prototypes. This could speed your development time some.

    Let me know if you have other questions.
