  • [SOLVED] Can't debug on new laptop (Windows 10) with new tools

    I have code that works on my old desktop just fine. I'm trying to move over to a new laptop, so I installed new versions of everything. I got it compile (eventually), but the debugger won't write to Flash & run code.

    Tools:
    working:
    Windows 7, J-Link V496m, Eclipse Luna, msys, gae-4.9_2014q4

    On the laptop:
    Windows 10, J-Link V512f, Eclipse Mars, msys64, gae-4.9_2015q3 (gae 5.3 compiled it differently, and didn't fit into the size constraints)

    Same J-Link debugger

  • Hi,

    could you please give J-Link Commander a try?
    J-Link commander is part of the J-Link software package, which is available free of charge here .

    • Start J-Link Commander (jlink.exe)
    • Type "connect" in order to start a debug session
    • Type in the target device name if asked (Or type "?" for a target selection Dialog)
    • Choose the correct target interface (JTAG/SWD/etc..)
    • Use a valid speed (Default: 4000kHz, try 100-500 if default does not work)
    • [JTAG only]JTAG conf can be default(most of the times)
    • You should now be successfully connected.
    If anything fails, could you post a screenshot of the complete session?

    Best regards,
    Niklas

  • So what has that shown me? The jlink tool can connect to the hardware, but not after downloading code to the hardware. However, I have it set to stop at main( ), and this code works on my old PC. Should I try an older version of jlink?

  • solved - bad Eclipse project settings

    Okay - figured it out myself after I had some time to think about it.
    The .cproject settings in Eclipse were messed up. At some point, in getting things to compile I ended up with two copies of the release configuration, and no debug configuration. So I was effectively loading the release code and then trying to debug it.
