Multilink Universal Rev.D used for FreeMaster Error
. May 16, 2020 at 03:41 AM (03:41 hours)
Staff: Takao Y.

  • hello, I have a problem ,when use the FreeMaster to debug my Target MCU MPC5744P , with the Multilink Universal Rev.D. 
    The free master make an error :Can not open BDM port.
    The FreeMASTER version is 2.0.



  • Greetings,

    Just for sanity check, could you download PROGPPCNEXUS and see if you can connect to your target? I just want to see if you have the right connections:

    Use PROG and just simply connect with your multilink universal. If it prompts you for a flash programming algorithm, then your connection is all good and I can focus on the DLL that is used by FreeMaster.


    • hello, 
      When I use the FreeMaster 2.5,the connection is good. It works ok. Both FreeMaster 2.0 and FreeMaster 3.0 can not work ok.
      Maybe it is the DLL problem .Could you have some advices about this ?
