TMDSHVMTRPFCKIT: Connection failed with PC

Prodigy 100 points

Part Number: TMDSHVMTRPFCKIT
Other Parts Discussed in Thread: CONTROLSUITE, TMDSCNCD28027F, TMDSCNCD28035, TMDSCNCD28335

Hi,

I have bought 2 TMDSHVMTRPFCKIT to develop an own control software for PMSM. After the first attempts with the example project one of the kits could not connect to the PC and the LD1 on M3 section do not light when I plug in the usb cable. I sent back the kit and it was replaced by a new one. I have worked with the new kits for about 2 month now. From one day to another one of the kits had the same issue and some days later the problem came up with the second kit also. What could be the problem? Is it burned out somewhere on the M3 section?

Thank you in advance,

Bence

    You may change a controlCard to look at if the controlCard was damaged or the onboard emulator was damaged, and check the power supply for controlCard is right. Did you use your oscilloscope with isolation power supply? If not, that maybe damage your board, even oscilloscope since the hv-kit is a non-isolation design, the high voltage power ground is connected to low voltage signal ground.

    Could you please download controlSUITE as the link below and install it, you may follow the guides (HVMotorCtrl+PFC_HWGuide.pdf and HVMotorCtrl+PFCKit_HowToRunGuide.pdf) in below folder to check the board.

    I have already swapped the controlCard, and i have the same issue, so the card is not damaged. The power supply is ok, the led on the controlCard, that indicates the power, light up. Then it must be the emulator. I did not use oscilloscope.

    I have controlSUITE and i have read the guidelines. I made everything as in the guides, so i do not know what i have missed.
    Don't you have such a problem earlier?

    Hi Bence,

    Could you please have a more detailed description of the operation process on these two kit? Like the below items. Thanks.
    1. Whats controlCard are you using?
    2. Did you use GUI or CCS? Which GUI? Or which example project if you are using CCS?
    3. Which JTAG emulator are you using? the one on HV-Kit, or the one on controlCard?
    4. Could you please try the connection without connecting the high voltage AC power supply, just the 15V dc power supply?
    4. What error is reported when the connection is failed?

    Hi Yanming,

    Here are my answers:
    1. F28035 ControlCard
    2. I have done the same things as it is written on the USB-Stick, i got with the kit, in the HowToFlashcontrolCards.txt file. One expection, I load the HVMTRPFCKIT-PM-ACI-GUI.out file to the ControlCard.
    3. I have used the JTAG on HV-Kit
    4. I have tried the connection without the AC power supply. The ControlCard is powered up, but the connection fails.
    5. It does not write anything, i just do not find the control card. in DeviceManager under Ports there is nothing related to the kit.

    1. There are two types of F28035 controlCard, one is isolation with on-board JTAG emulator, another one is non-isolation. You might use the on-board emulator if you use the isolation controlCard. You have to use the emulator on HV-kit if you are using non-isolation controlCard. For both controlCard, please refer to the guide or schematic to set right switches. For non-isolation controlCard, set both switches of SW2 to "ON", and disconnect J3 in M3 on HV-Kit. For isolation controlCard, set both switches of SW2 to "ON", and plug a jumper to J3 in M3 to disable emulator on HV-Kit.
    2. Only connect the 15V power supply, unplug the AC power supply, check the 3.3V/5V power supply (the jumpers of J3/J4/J5 in M6 are connected) on HV-Kit, and the 3.3V power supply on controlCard (LD1 is light).
    3. Connect USB emulator, open an example project with CCS, and then open emulator configuration file to test the connection. A more detailed operation could be found in below link.

    You might have to contact the distributor to report this connection issue to them if the connection is still failed.

    1. How can I be sure which type of controlCard I have? How can i check it?
    2. There is no J3 in M3 section on my kit, do you mean J5? - In the HWGuide for the J5 there is the following description: [M3] J5 – On-board emulation disable jumper.

    1. You should find a silk text (CC2803x ISO DIMM Rev 1.xx) on the control board if it's an isolation controlCard, without "ISO" If it's non-isolation one.
    2. Sorry, right, it's J5[M3]. Please refer to below setting.

    For controlCARDs with on-card isolated emulation:
    a. Populate M3-J5 (disables power to HVKIT emulator)
    b. Do NOT populate M3-J9 (disables JTAG connection)

    For controlCARDs without on-card isolated emulation, ex: TMDSCNCD28027F:
    a. Do NOT Populate M3-J5 (enables power to HVKIT emulator)
    b. Populate M3-J9 (enables JTAG connection)

    I have a TMDSCNCD28035 R1.2 controlCard. This was populated when i got the TMDSHVMTRPFCKIT.
    And i got another controlCard with the kit: TMDSCNCD28335 R2.2.
    As it is written on the website at the develeper's kit: www.ti.com/.../TMDSHVMTRPFCKIT

    Both controlCards are non-isolation one, so you have to use the emulator on HV-kit.

    To check the emulator on HV-Kit:
    1. Do NOT Populate M3-J5 (enables power to HVKIT emulator)
    2. Populate M3-J9 (enables JTAG connection)
    3. Connect the 15V power supply and turn on the SM1 switch.
    4. Create "Target Configuration File" for XDS100 emulator in the CCS project, and use "Test Connection" to test the connection.

    If failed, please follow below link to check the emulator driver.
    processors.wiki.ti.com/.../XDS100

    To check the controlCard:
    You might use an external emulator to check controlCard also if the kit worked well before.
    1. Populate M3-J5 (disable power to HVKIT emulator)
    2. Populate M3-J9 (enables external JTAG connection)
    3. Connect the external emulator to M3-JTAG

    Did the kit and controlCard work well before? If not, you might have to contact the distributor to report this issue to them if the kit can't work.

    The kit worked well before.

    The connection with the emulator on the HV-Kit is not possible.
    The connection with external emulator is also not possible.

    Should i contact the distributor?

    Did you try another bundled controlCard (TMDSCNCD28335)? what did the card happen? and what error did both cards report? Could you post a figure to show the reported error?
    You might contact the distributor to check the return/repair process if possible.

    Yes, I have tried with the other controlCard, but both gave the same error.

    C28xx: Error connecting to the target: (Error -183 @ 0x0) The controller has detected a cable break far-from itself. The user must connect the cable/pod to the target. (Emulation package 7.0.188.0)

    I have populated and connected everything as you wrote.

    You could check the emulator driver on your PC or other PC as below links. You might contact your distributor if you can't find the correct driver and the connection is failed.
