Cool . . . Trying: # mv /boot/efi/dtb/pine64_plus.dtb /boot/efi/dtb/no_pine64_plus.dtb # shutdown -r now does reboot just fine. As does: # rm -fr /boot/efi/dtb # shutdown -r now A cold boot also boots into the kernel. So no .dts or .dtb is needed for the Pine64+ 2GB . For reference after this: # mount /dev/label/PINE642GAroot on / (ufs, NFS exported, local, noatime, soft-updates, nfsv4acls) devfs on /dev (devfs, local, multilabel) /dev/label/PINE642GAboot on /boot/efi (msdosfs, local, noatime) # find /boot/efi /boot/efi /boot/efi/startup.nsh /boot/efi/EFI /boot/efi/EFI/BOOT /boot/efi/EFI/BOOT/bootaa64.efi /boot/efi/System Volume Information /boot/efi/System Volume Information/WPSettings.dat I have no clue if this hidden dtb contributes to the USB problem(s) or not: . . . cryptosoft0: <software crypto> NULL mp in getnewvnode(9), tag crossmp Timecounters tick every 1.000 msec usbus0: 12Mbps Full Speed USB v1.0 ugen0.1: <Generic OHCI root HUB> at usbus0 uhub0: <Generic OHCI root HUB, class 9/0, rev 1.00/1.00, addr 1> on usbus0 uhub_attach: getting USB 2.0 HUB descriptor failed,error=USB_ERR_SHORT_XFER device_attach: uhub0 attach returned 6 usbus0: Root HUB problem, error=USB_ERR_NO_ROOT_HUB mmcsd0: 32GB <SDHC SE32G 8.0 SN 09781303 MFG 07/2017 by 3 SD> at mmc0 50.0MHz/4bit/65535-block . . . My old -r308??? context not only could use usb devices but had the root file system on a USB SSD.

Looks like crochet does not need to produce the .dtb . It is not even clear that if a dtb/pine64_plus.dtb exists that it is used for anything. >> Is pine64_plus.dtb required for the likes of >> Pine64+ 2GB's?
