Yocto Gatesgarth, using meta-intel to build core-image-minimal
Intel D2700MUD mini-ITX mobo with D2700 Atom
Ordinary USB 2.0 flash drive
I followed the instructions in the meta-intel README, and had no problems
building the intel-core2-32 and intel-corei7-64 machines, as well as the
latter with an x32 tune. But whenever I try to boot any of them, I get the
following stuff from the kernel:
usb 1-6: new high-speed USB device number 4 using ehci-pci
usb-storage 1-6:1.0: USB Mass Storage device detected
usb-storage 1-6:1.0: Quirks match for vid 090c pid 1000: 400

Cannot find rootfs.img file in /run/media/* , dropping to a shell
At this point, it doesn't drop to a shell, but just sits there, responding
to keys by echoing them, so I have no way of investigating. Ctrl-Alt-Del
reboots.
Since there is no kernel serial output on this board, even though the kernel
command requests it, I videoed the startup, but didn't anything that looked
suspicious. I didn't see any message, though, about mounting anything in
/run/media.
As I've said, I've tried three different builds, totally generic except for
using the Intel BSP layer. I've tried two different USB drives. I've tried
it with EFI enabled and disabled in the BIOS. I've looked at the drive on
the PC, and the contents look normal. So why can't it find the rootfs.img
file, which is right there on sda, large as life? Anyone have any ideas what
I could be doing wrong?
