  • Debug freedom board FRDM-KL25Z in CodeWarrior with J-Link

    Hi,

    It's successful for me to use CodeWarrior to debug program with using Segger OpenSDA firmware. However, if I use J-Link debugger instead of Segger OpenSDA, "Debugger can not write memory" error is occured. Please kindly advise.

  • Hi,

    The KL25 is a Cortex-M0+ with 2 hardware breakpoints.
    So, usually when debugging in flash you will only be able to set 2 breakpoints.
    J-Link offers a unique feature called unlimited flash breakpoints which allows to set an unlimited number of breakpoints in flash memory.

    Unfortunately, CodeWarrior does not support this feature: segger.com/jlink-ide-integration.html
    We were already in contact with Freescale regarding this but it has not been changed so far...
    We will check with them again.

    In the meantime:
    Maybe you want to try another free IDE (GCC based, Visual Studio style)?
    emide.org
    It supports the unlimited flash breakpoints feature.

    Note: The unlimited flash breakpoints feature is free for evaluation only.

    Not sure if emIDE already comes with a sample project for the board you are using. If not, you may quickly check with the guy who is maintaining it?


    Best regards
