CCS/TMS320F28379D: Debug probe error

Part Number: TMS320F28379D
Other Parts Discussed in Thread: LAUNCHXL-F28379D

Tool/software: Code Composer Studio

Hi:

 I have a problem in debuging the borad using MCU--TMS320F28379D made by myself. The error shows as followed:

The problem project shown in picture is useful in LAUNCHXL-F28379D. After using TI's example device support works, the error still exist.  Laterly, I looked help from 

  and found that the error happened in running program after successful loading, shown as the following picture marked by red line:

But I do not know how to fix it because the code I used is the example code of TI and it works well in other LAUNCHXL-F28379D.  

Besides that,  the hardwared made by me doesn't include watchdog part and I do want to ask if the error happen because of the unconnection in pin XRS_N？

Can anyone give me some advice?

Thanks, Ditny.

    Hi Ditny,

    Are you sure about connection? There is a test according to this issue that you should do before anything else.
    Open the .ccxml file and then click on the "Test Connection" option. If everything is OK, you can see the confirmation massage.

    If the connection is OK you can see JTAG DR and JTAG JR connection success massage. If in this stage you have some error, you could not debug your program later.

    For more information, you can take a look at links bellow.

    I hope this helps.

    Regards,

    Hossein

    Hi, Hossein.

    Thanks for your reply.

    I think the connection is OK. But I still tried your method. And the result shows below:

    I am not sure about if you are talking about IR & DR connect result as shown.

    By the way,  today I connected the Vssosc pin (F28379DPTPS pin 122) with ground and some example type code can debug with no errors but  other code still can not. Is some pin of the chip broken in welding? Is there any quike ways to test it?

    Hoping for  reply!

    Thanks, Ditny.

    Hi Dinty,

    Yes, I was talking about IR and DR connection success. That's ok related to the image you sent.

    And the next mantter.
    You said you connected Vssosc pin to the ground and some codes were built and debugged with no errors but other were not. As you can see in the IC datasheet and the images bellow, If an external crystal is not used, this pin may be connected to the board ground.


    On the other hand you maybe want to use external oscillator so when you connect this pin (Vssosc) to the ground you are not allowed to do this. Take a look in your codes and try to find out if using external oscillator is needed for that code or not?

    Hi,Hossein.

    Very glad to receive your reply.
    In the board, I have used a passive crystal and the pin (Vssosc) connected to the ground which learned from the product LAUNCHXL-F28379D I've mentioned before. And the code debugging with errror on my board works well in that product. So I do not exactly know if the passive crystal is also calledexternal oscillator and if the code needs a external oscillator. But as I think, if it work with no error in the TI product and I copy it at this part , the problem comes probably not because of the passive crystal and the pin (Vssosc). How do you think?

    Best regards, Ditny.
