    Default SOC QSPI Flash loading issue

    I have a custom Cyclone 5 SOC board.
    I use the QSPI S25FL512.
    When I program the QSPI with the preloader from soceds command line, I see the following lines on the command line.

    So I think I programmed the QSPI flash memory successfully. The problem is I don't see any output on the terminal.
    VCCIO for that HPS bank is 3V. QSPI flash supply is 3V
    HPS_FLASH_DCLK does not have pull down resistor as in some evaluation boards.

    Note that when I put the same preloader on the SDCARD, it loads successfully.
