Next, you need to copy all the files and folders under the installation directory \SP7021\example\ spi_flash_axi to the spi_flash_axi project directory built above (the path is: installation directory \SP7021\ workspace\spi_flash_axi\). The program codes main.c; spi.c; and spi.h required for the Flash controller IP design practice are placed in the following paths:

1） Install main.c under In the install directory \SP7021\workspace\spi_flash_axi\ foldermain.c

2） Installspi.c in In the install directory \SP7021\workspace\spi_flash_axi\testapi\util\spi.c

3） Install spi.h in In the install directory \SP7021\workspace\spi_flash_axi\include\util\spi.h

Finally, as shown in the figure below, the mouse selects the red box 1, then clicks the right mouse button to appear the drop-down menu, and then selects the red box 2, refresh the copy action just now, so that the file just copied can be displayed in the IDE environment
