  • I am receiving the following error message when attempting to download and debug my IAR project using Multilink Universal FX:

    Fri Dec 16, 2016 14:55:59: ----- Prepare hardware for Flashloader -----
    Fri Dec 16, 2016 14:55:59: 2560 bytes downloaded and verified (9.43 Kbytes/sec)

    Fri Dec 16, 2016 14:55:59: Target reset
    Fri Dec 16, 2016 14:56:00: Unloaded macro file: C:\Program Files (x86)\IAR Systems\Embedded Workbench 7.2\arm\config\flashloader\Freescale\FlashK60Xxxx128K.mac
    Fri Dec 16, 2016 14:56:00: Execution failure in flash loader.

    It works fine using Multilink Universal device.

    Any thoughts on what might be going on?


  • Hi Jon, 

    Multilink Universal FX is significantly faster than Multilink Universal and you might have to slow down communication rate in order to successfully run a debug session with some target devices.

    When PEMICRO Connection Manager pops up, please try to drop down communication rate under Debug Shift Speed selection by a factor of 5-10 and see if that helps.

    Best Regards,
