programming CFlash & DFlash of SPC584C70 with UCyclone as single process

  • Hello

    I need to program both CFlash and DFlash parts in SPC584C70 micro.
    I use UCyclone for this task.
    Can I build the single process for UCyclone to do it in one procedure?
    In case it is possible I want to know how to organize the programming script and hex file for it.

    Thanks in advance,


  • Greetings,

    Just create one standalone image that programs both.
    Do something like...

    CM: Choose CFLASH algo
    SS: Select your object file for CFLASH
    EN: Erase CFLASH region if not blank
    PM: Program CFLASH
    VC: Verify CFLASH
    CM: Choose DFLASH algo
    SS: Select object file for DFLASH
    EN: Erase DFLASH region if not blank
    PM: Program DFLASH
    VC: Verify DFLASH


  • Hi Takao!
    Thanks for reply.
    Of course I have done it! I had error message: "Can't enter to program mode" after first part of the script.
    I tried to insert reset command after first part with same error message.
    And addition some delay after first part brings the same result.

  • Greetings,

    I would not automate your programming if you have not confirmed all your files and steps in PROG PPCNEXUS software, which is found in your cyclone software package. This is a step-by-step programming software and it will help debug the problems you may face. It's impossible to debug a scripted and encrypted image on the cyclone.


  • Thanks, Takao!
    It is interesting. I will try to use this tool.
