I think I ran into that screen issue now but it works after reconnecting the USB.
BUT, when I boot now without manual interaction it boots from NVME (ubuntu)
If I press a key and follow this page: [bug?] SiFive Unmatched default boot script update?
pci enum ; usb start ; run bootcmd_usb0
I get a direct kernel error.
