IAR external SPI_FLASH(W25Q128) download algorithm

[HXN]

Please give an example of IAR external SPI_FLASH(W25Q128) download algorithm for STM32F429IG, thank you

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
