My Pandaboard fails to enumerate a USB hard drive (used as a root
device) and panics. Earlier, I had to add a 2s delay to make u-boot
boot from "spinning" USB disks (flash drives are ok). OpenBSD needs
the same change to make hard disk enumeration successful. The hard
drive is plugged directly into one of the two pandaboard USB ports.
When I dd the miniroot-panda-72.img snapshot onto the same disk, there
is no panic and installation is successful. The panic (included at the
end) happens after rebooting. Going through a powered hub panics too.
Only a Y adapter to a port on another machine "fixes" the issue. Once
the enumeration is over this "jumper cable" can be removed. With this
patch, a single pandaboard USB port powers the disk reliably.
Comments?
Thanks for reading.
