  • Can the BDm be use to program the following memory location?
    0x40_0100 – 0x40_013F 64
    Program Once Field

    • Hi Nicholas,

      What Freescale microcontroller are you trying to program?

      • S12XFTM384K2V1

        • Hi Nicholas,

          I'm not 100% sure if we support that device since I can't find an exact match on our list. Do you have a datasheet or reference manual for it?

          Regards,

          • Hello Johnny,
            It is a variant of the HCS12X with 384 KByte Flash Module. Chapter 26 of MC9S12XEP100RMV1.pdf describes this specific module's 64 byte one time write memory.
            Your support is well appreciated!

            Thanks

  • Hello Johnny,
    The Program Once region in the IFR of the 9S12XF384 can be programmed through P&E BDM?

    • Yes, you would need two items:

      (1) P&E BDM interface (USB-ML-12, Cyclone Pro, USB-ML-UNIVERSAL,etc.)
      (2) PROG12Z

      Then you would need to go here to request an IFR algorithm:
