Pretty much all hardware comes with clear instructions and warnings about it. Without getting too technical I say that I have a 3A PSU the runs fine at least for me however quality of PSUs is a different story. It's a RockPro64 paired with a dual port PCIe NIC however I would recommend higher rated one if you plan to attach non external powered USB devices. >> >> We only support mainline u-boot, if you're using forks and/or patched versions you're kinda "on your own" and there's no (to my knowledge) support (yet) upstream for booting off NVME or SATA/AHCI. > > Well, at least u-boot2021.01 has all the needed support to boot a rockpro64 or pinebookpro from nvme/sata/usb/sd/mmc/net. > If you put u-boot into the SPI-flash it will boot from any of the above media. > > -- > Søren Schmidt > sos@deepcore.dk / sos@freebsd.org > "So much code to hack, so little time“ > yes, I used 2021.04-rcXX( master, self-compiled)… the strange thing on Rock960-board was that it needed some reboots until nvme was scanned correctly in u-boot-prompt. Thean it boots FreeBSD straight up and then hangs on mountroot> ( because there’s no /dev/nda0 or /dev/nvmeXX). I presume an electrical issue since it was once(only once) detected by adding nvme_load=„YES“& nvd_load=„YES“ in rc.conf. The u-boot patch related to nvme on that board also was based on a voltage-change . … I`ll post some debug-output the next hours… (`guess pcie has mem alloc issue from dmesg)… Anyone successfully booting from nvme on any aarch64-board ??
