Unable to communicate error, Windows 7, version C of multilink trying to connect to MCF51JM128

  • Hi there.   
    Getting Unable to communicate error, Windows 7 computer running PROGCF Programmer starter Edition , Have a new version C of multilink trying to connect to MCF51JM128.

    Have run Firmware update utility.

    Have dropped speed to slowest and multiples in between 0 (fastest) and the slowest.

    Have checked cable pin out - correct and since we don't have the FX we are supplying power and indeed we get a steady yellow light with power to the board.

    Have delayed time after reset to 6000 mSec

    Trying to Reprogram a power supply that has been programmed before (not by us) that uses a MCF51JM128.

    Any suggestions? More info you need?


  • Greetings,

    You did a great job giving me a lot of detail in your setup. I wish all customers would do that!!

    Are you using PROGCFZ or PROGCFV1? The PROGCFZ will not be able to connect to a MCF51JM128 because MCF51 targets are ColdFire V1/V1+. The demo/trial software is for ColdFire V2/3/4 versions of chips only.

    Unfortunately, we do not have any trial or demo or time-limited versions of PROGCFV1.

    Instead of demo or trial, what we do is have customers purchase the software and if they have troubles they should open a support ticket by going to support page -> Support requests. If our technical support cannot get your setup working even though you got the right hardware and software, then we will help you in getting your money back.

  • Sounds good.  Bought the other software recommended and now can communicate (thank you very much for the prompt and accurate response) but now it is asking me to specify a Programming algorithm to use

    As noted above I have a MCF51JM128RM chip on board.... what Programming algorithm should I chose?

    Thanks Carl

  • Checking list it looks like I would want to use the 

    freescale 51JM128-1X32X32K.CFP

  • Greetings,

    The algorithm you should use is the Freescale_51JM128_1x32x32k.CFP. It is really the only choice you got that matches your device.

    • In and up.  Thanks!

      However cannot find a help file for PROGCFV1 - at least a general user guide?

      Assuming I have to erase before programming or does the program icon automatically erase.

      Specifyed my .elf file as the source

  • Found the user guide in the download area of the PEmicro files on my computer.  Will read it and get back to you if I need help.  Thanks!

  • Should be good to go

    Will use this sequence (which is what I thought it should be) RE, (have already set CM), EM, BM, SS, PM

    from your manual

    Example Programming Script File
    The programming script file should be a pure ASCII file with one command per line.
    This is the CFG file in the previous examples.
    An example is:
    RE ;Reset the MCU
    CM C:\PEMICRO\Freescale_51QE128_1x32x32k.CFP ;Choose Flash Module
    EM ;Erase the module
    BM ;Blank Check the module
    SS C:\PEMICRO\TEST.S19 ;Specify the S19 to use
    PM ;Program the module with the S19

  • Final comment for now... all good worked a treat.  Many thanks for the help!
