Chapter 12: SPI Serial Flash
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.
A disclaimer notice appears on the screen. Press the Enter key to continue. The entire
programming process takes slightly longer than a minute, as shown in
After programming the SPI Flash, remove jumper JP8, as shown in
properly programmed, the FPGA then configures itself from the SPI Flash PROM and the
DONE LED lights. The DONE LED is shown in
