    Check what documentation and examples IAR provides for .flash and .mac implementations

    What doesn't jump to the main() function?

    The W25Q128 is on SPI4

    PE4 CS

    PE2 SCK

    PE5 MISO

    PE6 MOSI

    Your function,if it's running properly should read 100 bytes into a buffer, and then loop.

    Does any of that run?

    Any other code you've written run?

    Can not run, if the red circle mask program of picture 1 can normally read the data of external FLASH through the download algorithm, picture 2 is not normal, please see the attachment
