This is an RPi3B running stable-13, system and ports up to date as of yesterday. Here's an example session following a failed boot attempt: U-Boot> usb reset resetting USB... Bus usb@7e980000: USB DWC2 scanning bus usb@7e980000 for devices... 6 USB Device(s) found scanning usb for storage devices... 1 Storage Device(s) found U-Boot> usb part [I think some information about the disk should have been displayed] U-Boot 2022.04 (Sep 23 2022 - 17:28:32 -0700) DRAM: 948 MiB [...usual startup output] Are there any debug switches for u-boot? I've looked a bit and what I find is either stale or not implemented. There's a reference to a "log" command, but it does not seem to be recognized. It does seem clear that the presence of a timeout file makes no meaningful difference. Boot succeeds rate is less than 50% This is using an unmodified u-boot-rpi-arm64 built locally. The system has no microSD installed, u-boot is started from the USB disk (which is found by firmware without trouble). If setting up a microSD to start u-boot alone would simplify matters that seems worth a try. Hints much appreciated! Once the machine boots into freebsd it seems to work just fine. The problem appears to be with u-boot only. Thanks for reading, bob prohaska
