Error -150 @ 0x0

Hi

i am using c2000 launch pad(F28027)  to generate complementary pwm with dead band. These pulses are used to drive the mosfets in DC-DC converter. one of the mosfet is  at low side and another is at higher side. I am using isolated gate driver with isolated power supply to drive these mosfets.  SL7407 buffer ic  is used between c2000 launch pad and and opto coupler . Launch pad is powered through usb cable .I am getting following error  when i am increasing my input voltage of the dc to dc converter from 12V to 24V.

"C28xx: Error: (Error -150 @ 0x0) One of the FTDI driver functions used during configuration returned a invalid status or an error. (Emulation package 5.1.73.0)"-  Please tell me how to overcome this problem.

Regards

    Hi

     Thank you for the help . i gone through the xds100v2 troubleshooting .i configured my FDI driver .But still the problem existing .

     I am getting error signal as follows

    "C28xx: Error: (Error -150 @ 0x0) One of the FTDI driver functions used during configuration returned a invalid status or an error. (Emulation package 5.1.73.0)"

    C28xx: Trouble Halting Target CPU: (Error -150 @ 0x0) Internal error: Invalid error code. Restart the application. If error persists, please report the error. (Emulation package 5.1.73.0)

    C28xx: Unable to determine target status after 20 attempts

    "C28xx: Failed to remove the debug state from the target before disconnecting.  There may still be breakpoint op-codes embedded in program memory.  It is recommended that you reset the emulator before you connect and reload your program before you continue debugging"

    Apart this GEL window is also appearing.

    Regard

    Shelas, try uninstalling the drivers and re installing them. This might solve your problem.

    Keep me informed.

    Hi

     i tried with another 28027 kit and the problem remains.Drivers are configured a shown in troubleshooting section.  i am using the codes given in  c2000 teaching ROM for complementary pwm with dead band. But the switching frequency is 100 kHz . when i am connecting the power circuit , then the error coming. with out power circuit i am getting pwm output. so i hope code given in teaching rom is not making the problem. it may due to some noise from my power circuit.

    please tell me how can i connect separate power supply to c2000 launchpad . so that i will get JTAG isolation .In that case i hope my problem may solve.

    If you check the schematics, Vusb is fed to LDO which inturn powers both on-board emulator and controller. I don't think your PC usb port would propagate any noise to launchpad. Did you observe any noise (in Launchpad) on DSO?
