I believe there is nothing board-specific about this memory initialization issue, but it might be no other Armbian board has this combination of rk3399 and LPDDR4. Else there is something specific about the memory set up on the Helios64 hardware. On the Helios64 random memory errors happens when using the U-Boot DDR intialization code for rk3399. Switching to the rkbin rk33 933MHz v1.25 allows this testcase to run more than once without a memory error: for i in $(seq 1 100);do python3 -c "import pkg_resources" || break;done Could be LPDDR4 specific. Workaround https://github.com/armbian/build/issues/4761 "free() invalid pointer". A proper fix would be to fix u-boot own lpddr4 initialization code for Rockchip but I miss the Rockchip DDR binary settings to compare with. How Has This Been Tested?
