LPC1800 with S25FL256SA flash memory on SPIFI problem

SantoshMengade

LPC1800 is interfaced with external flash memory S25FL064P1F on SPIFI interface. The code present in external flash memory S25FL064P1F is read and executed properly. To increase memory size we just replaced S25FL064P1F by S25FL256SA1F00 on board and stored same code in it. We are observing that code execution speed has reduced significantly in new flash memory S25FL256SA1F00.

I want to know what need to be done to increase code execution speed from new flash memory S25FL256SA1F00.

Please help me.

Thank you!

    I also encountered this problem for my application for another uC. I solved like below;

    In target options,
    select "Utilities", select your debugger and click "Settings",
    There are Cortex-M Target Deriver Setup menu.
    select "Flash Download" tab, there are a "Add" button.
    please add your Chip's Programming Algorithm.
