  • [SOLVED] Program stops at phantom breakpoint

    Under debugger, my program stops at breakpoint
    - but there is no breakpoint at or near the location it stops.
    Running program not under debugger works AOK.
    Always stops at the same spot, every second or two.
    Picture attached shows the stopped debugger.

    Jlink Base running 6.80d, NXP MCUXpresso, Kinetis K64F
    I'm using debug console for printf output which works fine.
    Thanks in advance for any ideas or advice,
    Best Regards, Dave

  • Hi Dave,
    Thank you for your inquiry.
    There is no such issue known to us.

    Could you please send us a J-Link log file? How to enable:
    wiki.segger.com/J-Link_DLL#Enable_J-Link_Log_File
    Do you use custom hardware or an evaluation board? In the latter case which one?
    If custom hardware, do you experience the same problem on an evaluation board?

    Best regards,
    Fabian

  • Thanks Fabian - Log file is attached.
    This is a custom board, probably our 6th design with K64F.
    Haven't seen this problem with earlier efforts - not sure what's changed.
    Thanks,
    Best Regards, Dave

  • Hi Fabian - This problem seems to have been caused by a power supply problem (dubious 3.3v) on the prototype board I received (fabrication error, dope-slap to the assembly house). Another board works AOK. Amazing that the problem was reproducible many times!
    Apologies for wasting your time with this.
    Thanks as always for the help,
    Best Regards, Dave
