Hi,
We are using Cyclone V SoC SX series for our design, and we take Cyclone V SoC development kit as a reference.
On the development board, it uses a CPLD and NAND flash for programming fpga.
But we would like to make the hardware design simpler, so we plan to use the QSPI and SD card only.
This means we would like to configure FPGA from HPS from QSPI flash, the question is how to put both the preloader and fpga image into the same QSPI flash (on the HPS side). I know the preloader is generated based on the handoff from Quartus, can the preloader includes the FPGA image also?
Thank you in advance for any response or reply.

Hi,
Yes you can configure the FPGA from preloader. But you need to make sure: 1. The next boot stage (U-boot) needs to be located in QSPI, 2. The FPGA image is located in QSPI too.
You can refer here for more info and steps to guide you (Jump to FPGA Configuration from Preloader):

Let me know if you need more help.
