Can F28335 controlCARD be used for TMDSHV1PHINVKIT?

Other Parts Discussed in Thread: TMDSCNCD28035

Hi,

Our lab has bought two TMDSHV1PHINVKITs and two TMDSHVMTRPFCKITs. 

As you known, the default  settings are F28M35 controlCARD used for TMDSHV1PHINVKIT and F28335 controlCARD used for TMDSHVMTRPFCKIT.

Now, we are familiar with F28335 controlCARD, not familier with F28M35 controlCARD.

So, can we use F28335 controlCARD for TMDSHV1PHINVKIT control with our own control software.

Thamks.

  • Hi Yekin,

    Does the DIM socket match...? if it does then why not. All you need to do is study the schematics and work out with the feasibility part.

  • Dear Gautam,

    Yes,  the DIM socket matchs. 

    I have got it. Thanks.

    Does it means all TI's conttrol CAD can match all TI's application KITs if the DIM socket matchs?

    Thanks.

  • Hi Yeqin,

    Generally, any controlCARD can plug into any application board and be able to perform the major functions available on the EVM board.

    However, there may be some functionality which will not work.  Realistically you should look at the chip and the EVM baseboard to see what parts of the EVM you can and cannot make work.

    Based on a quick look, you should be able to use the board with the F28335, with one note.  I do not believe that any of the example software for this kit is using the internal comparators available on the newer F28M35/F28035 C2000 MCUs for protection of the power stage.  However, if it does, the F28335 will not have internal comparators to do this. 
    (even so, this shouldn't be too big of a deal because there is circuitry built on the EVM which feeds a square wave signal to a TZ pin for overcurrent/current-limit protection and you can take advantage of it)

    From a software perspective, you'll need to invest some time in making the system work with the F28335.  If you're hoping to use the existing software as a place to start, the F28035 project will be the better option to look at.


    Thank you,

  • Dear Brett,

    I have got it. I will notice them when i replace another control card.
    Thank you for your information.

  • Dear Brett and Gautam,

    Yesterday, I used F28335 controlCAD and F2808 control CAD for TMDSHV1PHINVKIT. I found a problem that I cannot connect target MCU throgh 14-pins JTAG on board with both controlCAD.

    I used TDS-510 emulator, the CCS version is CCS3.3. I have shorted the JP6 Jumper.

    Did I miss someting that case the connection problem? Or anything else.

    I also found the 6th pin of JTAG was not removed in TMDSHV1PHINVKIT board. I removed 6th pin of JATG.

    Thanks.

  • Based on the schematics, I believe that JP4 should also be populated.  Is it?

    Thank you,
    Brett

  • Dear Brett,

    I have confirmed that the JP4 was shorted.
    And the "target indication led" changed to dark when I powered on MCU.
    Does the problem about the JTAG voltage level?
    I used the pretty old JTAG, it need the voltage very close to 3.3V.
    If so, we plan to buy a USB200 JTAG Emulator. Do you get other suggestions?

    Thanks.

  • Hi Yeqin,

    Some of us in the lab just tried to use the XDS510USB on this board and couldn't use it to connect to a TMDSCNCD28035 controlCARD.  We then tried with an xds100v1 emulator and were able to connect.

    I'm not completely sure why the XDS510USB wouldn't connect on this particular board, but in a previous kit we found that changing out the isolation chips from ISOxxxxC to ISOxxxxM helped resolve the issue.  Another potential resolution could be to change some of the emulator settings (reduce the clock rate, etc) from inside CCS.

    Of course the simplest solution may be to buy a new emulator.  I can specifically say that the xds100v1 did connect.  I cannot speak for others since we didn't have any other emulators readily available to us.

    The xds100v1 is relatively cheap and you can find some potential sellers at the link below (for reference we had the Olimex):

    Thank you,

  • Dear Brett,

    Thank your for you kindly reply.
    We will think about to purchase a USB200 or others Emulator.
