QM_Spartan-7 SPI Boot
In default, XC7S15 boots from external SPI Flash, detailed hardware design is shown in below figure. The SPI
flash is using N25Q064 manufactured by Micron, with 64Mbit memory storage.
Figure 2-11. SPI Flash
The FPGA boot sequence setting M0:M1:M2 is configured as 1:0:0 which indicates FPGA will boot from SPI
Flash after power on. In default, the jumper J3 is under open status.
Figure 2-12. M0:M1 Hardware Settings
The LED D2 will be turned on after the FPGA successfully loading configuration file from SPI Flash during
power on stage. In this case, LED D2 could be used as FPGA loading status indicator.
