It is time to upgrade systems here, and it seems that arm32 has been left in the scrap heap. Shame with all the Allwinner boards I have... Is there a list of tested aarch64 systems? I am particularly looking for ones with 4GB memory and sata support. I have never been a fan of Raspberry, and with the RPi4, you have to get at least a sata extension board. I do like it still works with 5v; 3a is no problem for me with my Anker power supply, but I suspect more will be needed once you add the sata expansion card and drive (thus whatever is in the list of other aarch64 systems should have power requirements). Anyway, as I go back before Centos1 (I believe it was called WhiteHat), I need to go with the flow. Hard to believe Centos has managed for so long. By Centos.
