  • [ABANDONED] CPU Core error JLINK w/ TMS570LS0714

    I'm trying to boot up my tms570ls0714 that's on a custom board but when debugging I get the following issue:

    JLink Error: Could not start CPU core. (ErrorCode: -1)

    and after a few minutes I then get cpu_reg_set() register 0 is already set

    I currently debug using Code Composer Studio 7.4.0 with jlink properly set as the target debugger. When I debug, the JLINK popup shows that it's verifying the connection and proceeds with no errors; I see some initial register values after a while but I am unable to resume debugging or running code and it gives me error code -1. I've also tried using OZONE to debug and I get the same error.

    I've provided my connected pinout below



    I'm really at a loss for why this is happening as I've been unable to find any past posts about it and any help would be appreciated.

  • Hi,
    Thank you for your inquiry.


    Could you please send us a J-Link log file? How to enable:

    Does the issue also appear when using an evaluation board?
    If yes which evaluation board exactly?

    Best regards,

    I've attached my log below, at the end is where you can see the errors when I try to resume with debugging after it halts on its own.

    Unfortunately we don't have the same cpu on a dev board, but it runs properly on a tms570ls1224 launch pad.
  • Hi,
    Unfortunately, we were not able to reproduce this issue.

    Setup:
    Evaluation Board: HERCULES socket board with an TMS570LS0714.
    Emulator: J-Link Plus V10
    Debugger: Ozone V3.20f

    Please understand that there is not much more we can do here without a reliable reproducer on an evaluation board.
    If everything works as expected on the launch pad (with the same application),
    the issue is most likely connected to your hardware.

    If you can provide us with a reproducer that works on an evaluation board,
    we will of course look into this.

    Best regards,
    Fabian
