Lower the DDR frequency to 624MHz seems to solved the issue.
I'm not sure, since ddr can be keyrole IP during relocation and falcon mode(which I'm trying) but we can make sure the ddr test in uboot atleast?
Some issues will only appear under heavy load, which is difficult to emulate by u-boot.
To expose the issue by memtester I used two background tasks: one is infinite tinymembench, the other is building a Linux kernel with -j4.
thanks!
