ContributorCustom board on Cyclone V HPS SDRAM preloader test
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.
ContributorThis made us hard to believe that the EMIF is not buggy or there are some configuration is wrong.
See logs of DUT with MT41K128M16JT-125:K (single ide) fly-by layout board.
Under distro after boot stressapptest able to run continuously w/o crash drop or even halt.
Please do internal engineer examine such issue.
