CCS/TMS320F28035: Troubleshooting Procedure for error"C28xx: Failed CPU Reset: (Error -1137 @ 0x6) Device is held in reset. Take the device out of reset, and retry the operation. (Emulation package 6.0.576.0)"

Part Number: TMS320F28035
Other Parts Discussed in Thread: TMDSCNCD28035, , CONTROLSUITE

Tool/software: Code Composer Studio

Hi!,

I am using Piccolo F28035 (TMDSCNCD28035 R1.2) control card in 1KW inverter evaluation kit (https://www.digikey.com/product-detail/en/transphorm/TDPV1000E0C1-KIT/TDPV1000E0C1-KIT-ND/6207312

I checked the forum for troubleshooting this problem, but there are several suggestions and different. So its a bit confusing on how should i proceed.

What can cause this problem and what could be the best way to start troubleshooting this one or any specific procedure which should i follow?

I would be highly grateful for your suggestions.

Thank you

for one of the error message, which says target configuration does not match, as presented in the information, i had selected the device type TMS320F28035 in target configuration file.

 

Thank you

    Hi Samir,

    Have you checked the XRSn pin of device to make sure device is not held in reset (as mentioned in the error message)?

    Hi Vivek,

    Thank you so much for the prompt response. However, i am new to this one. Could you please help to elaborate a bit more on this one. I checked the datasheet and some information regarding XRSn pin, but still confused and not clear how do i check this one. Thank you so much.

    Samir,

    Probe the XRSn pin of device to see it is not stuck to '0' or transitioning to '0' during run time.

    Hi Vivek,

    Thank you so much for your prompt response. As suggested i checked the output of the XRSn pin of the device. The voltage obtained as observed from oscilloscope is 3.3 V. Furthermore, LED2 (LD2) is turns stably RED. LED1 is stable GREEN, LED3 is off. I tried to search the meaning of this RED indication, but i could only find it is controlled by GPIO 31 (As per the pin description from the control card manual its on pin 9 for 80 pin package).

    The voltage observed here, in the oscilloscope is

    Thank you so much

    Regards

    Hi Samir,

    For support on this kit, I would recommend contacting Transphorm USA to help with this issue.  Since this is their kit, I believe they should be able to help.

    A few things I'd check:
    1) It appears that this kit comes with a F2803x controlCARD.  There probably aren't any differences between the controlCARD that's in the kit & the one that TI sells, but I cannot be completely sure. 
    2) If you're trying to connect the kit up to CCS.  If so, please make sure that JP1 is placed.


    Thank you,
    Brett

    Hi Brett Larimore

    Thank you so much for your response. Actually the problem is not with the kit. The kit comes with F28035 control card, and the problem is only with the control card. When i replace the control card with another F28035 control card i can load program and run it. While the problematic control card cannot load the program when i place it on another kit. So, its only issue with the control card. Regarding jumper JP1, its placed while trying to connect the control card(kit) to CCS. I would also in the meantime contact with the transphorm USA. But is there any further troubleshooting i can carry out to resolve this issue of TI control card?

    Thank you

    Best Regards

    Hi Samir,

    It's interesting to know that the system works when you use a different F28035 controlCARD. 

    Are the two controlCARDs completely identical (same revision, etc)? Which of the two cCARDs works, the one that came with the kit or an alternate one?

    I am feeling like potentially the cCARD in the Transphorm kit may not be exactly the standard controlCARD that TI sells.  Alternatively, I am thinking that the one that isn't working is somehow damaged. 

    To answer your original question, the green LED (LD1) signifies that the controlCARD (and therefore the F28035) is powered.  LD2 and LD3 are GPIO controlled LEDs.  Their state is therefore controlled by the GPIO-31 and GPIO-34 nets.  Note that these GPIOs are configured as inputs & pulled high by internal pull-ups at power on.  External circuitry may also pull the signals one way or another.  They do not necessary show any kind of problem, unless software is written to make them mean something - but this isn't done out-of-the-box by TI.


    Thank you,
    Brett

    HI Brett Larimore

    Thank you for your prompt response. The two control card are identical with same version/release, TMDSCNCD28035 Piccolo Control card (R1.2). The problematic control card doesnt work in another experimental kit and prompts same error as shown in the first picture of this discussion.
    I also feel the control card has problem, but difficult to pinpoint exactly where. Could you please suggest further troubleshooting process.

    Aside, if its faulty, we can claim the warranty within 3 months, as per TI (TI warranty is 30 days from the date it is received by the customer and 90 days if defective). We received the total kit in March 28 this year.

    Thank you
    Best Regards

    Hi Samir,

    Hmm.  I'm nearly out of ideas.  Can you try putting both switches in SW1 to the 'OFF' position (open) and see if this will enable CCS to connect?

    Let me know how this works.  Once we run out of debug options we can start down the replacement path.


    Thank you,
    Brett

    Hi Brett,

    Thank you for the continuous support. Do you mean, putting both switches in SW2 to 'OFF' position, since SW1 has only one switch. SW2 is for boot option, while SW1 is for on card RS-232 connection. I tried with SW2 both switch OFF to check, still the same error comes. Should  I try further with SW1? The CCS can connect with control card, the link is ok but the problem is while trying to load the software.

    Thank you

    Regards

    Hi Samir,

    Sorry for my mistakes in my last post.  Yes, I meant SW2.  And I also meant to try when using Wait Boot mode - GPIO37 as high, GPIO34 as low.  Can you try this setup and see if you're able to connect?

    Can you also try loading the following example project:

    Thank you,

    Hi Brett

    Thank you for your prompt response. I tried like you have said in the last post and also tried loading the "timed_led_blink" program, still i am getting the same error. Is there any further troubleshooting we can do or should we proceed for replacement?


    Thank you

    Hi Samir,

    I agree that this appears to be an issue with hardware and a return is warranted.

    Please contact the person you bought the F28069 controlCARD from, and make them aware of this email thread.  It should help you accelerate getting a replacement.  If you have issues with this, please friend request me here on the E2E forum.


    Thank you,
    Brett
