Hi,

The preloader should be placed at the beginning (0x0) of the QSPI address space.

The "Building Bootloader for CV and A10" guide in RocketBoards provides an example on how OS (Linux), Preloader (4 x SPL and Full U-Boot) are prepared and flashed to QSPI via quartus_hps (chapter Cyclone V SoC - Boot from QSPI).

See "C. QSPI Binaries"

Hope this helps.
