When I use Orange Pi Prime to do some heavy compliation tasks, the

there's no really reliable way to detect DRAM stability except try

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!
