TMDSHVRESLLCKIT - HV Resonant LLC Developer’s Kit - ERROR PROGRAMMING FLASH

Other Parts Discussed in Thread: CONTROLSUITE

Hello, I have a TI HV Resonant LLC Developer's Kit that has a 28027 piccolo processor on it.

I am going through the steps in the kit's software reference guide.  I have verified the following:

   1) Insert a F28027 control card into socket [Main]-H1.
   2) Connect your computer to the board using a USB cable. [M4]-LD1 near the USB connector [M4]-
       JP1 should turn on.
   3) Verify the following jumper settings:
       No jumpers are placed on [Main]-J1,J2.
       Jumpers are placed on [Main]-J3, J4, J5,J6.
       Jumpers are placed on pins 1-2 on [Main]-J7,J8.
       A jumper is placed on [M4]-J4.
   4) Connect the 12 VDC power supply to [M3]-JP1 to power the Auxiliary power rail.
   5) Connect a 390VDC, 1A (max), power supply across [Main]-BS1, BS2.
   6) Connect a 300W (max) load across [Main]-BS3, BS4.
   7) Set the power switch [M3]-SW1 so that it is pointed towards the “Ext” label. [M3]-LD1 should turn on and a        green LED should turn on on the controlCARD.

I see that the piccolo control board has the single green LED lit.

I then proceeded to import the project and create the new target (using CC  Version: 4.2.1.00004) to run it.

I try to debug the project and I get the Flash programming errors in the screen shot above (see red).

The kit comes with an Isolated XDS100 USB JTAG emulator that I am using.

Any help as to why I can not debug/program would be greatly appreciated.

Thanks,

Brent

    Hi Brent,

    Are any of your components on controlCard getting heated up esp. the controller? Please check and let us know. Also using the help of oscilloscope try check the voltage levels on the controlcard esp towards the controller.

    Regards,

    Thanks for the response Gautam.  None of the components on the board feel particular hot.  I will look at voltages.  Any in particular?  Any other thoughts?

    One other thing.  I do NOT think I bricked the flash.  Below is a capture of the pass word section.

    If I can't resolve this, I may just create a RAM target for the LLC kit  (not sure why it did not come with one) so I can start playing with the code.

    Thanks again,

    Brent

    Hi Brent,

    Can you try programming the FLASH using the flash_f28027 example project? If you get the same error, the problem has something to do with this particular controlCard or device.

    Let me know how this goes.

    The flash_f28027 example project can be found in the examples folder in controlSuite.

    Hi Hrishi,

    Thank you for the response.  I tried the project you specified from the controlSuite with the same result:

    C28xx: Flash Programmer: Error erasing Flash memory.
    C28xx: Flash operation timed out waiting for the algorithm to complete. Operation cancelled.
    C28xx: Trouble Writing Memory Block at 0x3f65f8 on Page 0 of Length 0x16
    Cannot write to target

    I had also tried the LED flash example.

    I have ordered another control card.

    Brent,

    Thanks for the update. Has FLASH programming ever worked on this machine with the same CCS environment? If it hasn't or if this is the first time you are using the FLASH programming from CCS, the problem could also be with CCS installation. It may be that the FLASH tool or CCS did not get installed right.

    I suggest trying FLASH programming of the new controlCard. If you get the same result, you may try uninstalling and reinstalling CCS.

    Thanks.

    Hi Hrishi,

    I have used this same CCS environment to program MSP430 parts numerous times.  This is the first time programming a C2000 part.

    Thanks,

    Brent
