Custom board on Cyclone V HPS SDRAM preloader test

Dear Intel and all, Apart from the DDR3 topology. The first stage testing shows a very puzzling behavior. BOARD : Altera SOCFPGA Cyclone V Board CLOCK: EOSC1 clock 50000 KHz CLOCK: EOSC2 clock...

    The final result is that even with a fly-by routed topology there are no issue on both 1.5V and 1.35V DDR3 DDR3L.
    The MT41K128M16 /w 1k page size shows no sanity issue on memtest stresapptest on distro.
    UBOOT memory normal test also passed w/o any errors.

    So after short testing we can only assume there are inherent bug on Quartus 18.1? or HPS IP.

    No matter it is /w or /wo the board settings no drop no crash no stuck.

    So the case ends here.
