CCS/TMS320F28069: Trouble Halting Target CPU Issue

Part Number: TMS320F28069
Other Parts Discussed in Thread: C2000WARE

Tool/software: Code Composer Studio

I am using 28069 chip, CCS 8.1 and XDS 100v2. I often have below picture's issue. 

Trouble Halting Target CPU: (error -1156 @0x0), Device may be operating in low-power mode. All of the variables in real time debugging will be frozen. "Reset CPU" or Restart in debugging do not working. I have to to flash the code. 

Can you please give me a hand?

    Hello,
    Assuming you did indeed press "Yes", was there any additional message/error that appeared?

    Thanks

    Dear Ki-Soo,

    Thanks for the reply. 

    I have attached two pictures for your information. 

    There will be many windows pops up like the first picture. Then the debugging section will be frozen. 

    Then the second window will pop up. I have to reflash the code.

    Hi Ki-Soo,

    There are some lines from console:

    "C28xx: Trouble Writing Memory Block at 0xeb4c on Page 1 of Length 0x2: (Error -2130 @ 0xEB4C) Unable to access device memory. Verify that the memory address is in valid memory. If error persists, confirm configuration, power-cycle board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 8.0.27.9)
    C28xx: Trouble Halting Target CPU: (Error -1156 @ 0x0) Device may be operating in low-power mode. Do you want to bring it out of this mode? Choose 'Yes' to force the device to wake up and retry the operation. Choose 'No' to retry the operation without waking the device. (Emulation package 8.0.27.9)"

    Ok, so you have successfully code loaded and running. When you halt the target you get that issue. And pressing YES does not help. You are required to reflash to code again to get the target in a good state.

    Is this correct?

    Hi Ki-Soo,

    Yes.

    During the debugging, many of the "GEL Expression" windows will pop up and the "Trouble Halting Target CPU" window will pop up.

    Then I have to re-flash CPU.

    I think the issue come from why the "GEL Expression" window pop up.

    Thanks!

    Do you know if you application is indeed going into low power mode during your debug session?

    Hi,

    Unfortunately I couldn't reproduce this issue, therefore I suspect the device is being somehow locked or powered down by external factors. 

    I used the project Example_2806xStandbyWake from the C2000Ware version 1.00.04.00 and was able to properly take the device out of the low power run mode via CCS. The procedure I am following is:

    Also, a similar result is obtained if I wake up the device by grounding GPIO0 (as the example code uses for wakeup):

    I am using CCSv8.1.0 with my F28069 Experimenter's Kit connected via XDS100v1. 

    Regards,

    Rafael
