Preloader can't access to QSPI

Hi All,

I'm working on a custom board - assembled with Arria 5 that boot from QSPI.

When i power on my board I can see on the tera term the peloader printouts ,but after preloader finishe his work

and try to read out the uboot from QSPI to DDR - it face some difficulties.

below are the printouts ( with the errors ) from the UART0 termial :

CLOCK: F2S_SDR_REF clock 0 KHz

CLOCK: F2S_PER_REF clock 0 KHz

CLOCK: MPU clock 800 MHz

CLOCK: DDR clock 532 MHz

CLOCK: UART clock 100000 KHz

CLOCK: MMC clock 488 KHz

CLOCK: QSPI clock 400000 KHz

RESET: WARM

Please advise,

Thanks Moran.
