MPC562 External Flash Address

  • Hello,

    I am trying to read the external flash connected to a MPC564 custom board. It's a 2MB device. The IMMR register's ISB field is set to 0b000.

    I am trying to find out what will be the mapping address of the external flash, can you point me in the right direction please?


  • Hi Dick,

    We might already have an algorithm that support your external flash and will allow you to read or program it. Did you check the files in the supportFiles folder to see if any of them have the part number and configuration of your flash? Our algorithm will take care of setting up the IMMR and mapping the chip selects so you don't need to.

    You can also fill our this flash algorithm request form and we will help you locate the correct one.

    If we find a matching algorithm, then you just need to load it in PROGPPCZ to read out or re-program the flash.

    • Hi,

      I was able to find an algorithm, suited for my case. Thanks

      • Great! Is the microcontroller a MPC562 or MPC564? Which .pcp algorithm did you end up using?
