Programming the SPI Flash with the XSPI Software
Open a command prompt or DOS box and change to the XSPI installation directory.
The XSPI installation software also includes a short user guide, in addition to XAPP445.
Type xspi at the prompt to view quick help.
Type the following command at the prompt to program the SPI Flash using the SPI-
formatted Flash file generated earlier. This verifies that the SPI Flash is indeed an M25P16
SPI Flash and then erases, programs, and finally verifies the Flash.
C:\xspi>xspi -spi_dev m25p16 -spi_epv -mcs -i MySPIFlash.mcs -o output.txt
