Hi Brian, There is no definitive answer for the maximum frequency of the F2SDRAM bridge. For Cyclone V, F2SDRAM bridge access is managed by the SDRAM subcontroller system, and the operating frequency for the L3 Interconnect, which the F2SDRAM bridge uses has a maximum clock rate of 400 MHz for the -1V speed grade. https://www.intel.com/content/www/us/en/docs/programmable/683126/21-2/interconnect-block-diagram-80449.html https://www.intel.com/content/www/us/en/docs/programmable/683801/current/hps-clock-performance.html The available throughput is shared among all F2SDRAM bridges instantiated in the system. As more bridges are added, we will need to reduce the input frequency to ensure reliable operation and to stay within the total bandwidth limits. Please also note that the above calculation is theoretical. In practice, real-world throughput may be lower due to various system factors.

Hi dpeng Please refer to our User Guide for the Cylcone V Boot from QSPI. https://altera-fpga.github.io/rel-25.3/embedded-designs/cyclone-v/sx/soc/boot-examples/ug-linux-boot-cve-soc/#2-cyclone-v-soc-boot-from-qspi In the steps there are 4 different binaries that was created u-boot-with-spl.sfp, socfpga_cyclone5_socdk.dtb, zImage and core-image-minimal-cyclone5-rootfs.jffs2. These files are required to boot into the linux environment. These binaries are flashed into the QSPI Image separately into the address shown in table below: Regards tehjingy
