I indeed see that sata works at the first login prompt. However, I cannot
mount the rootFS on sata, as apparently the fs mounting is done before the
initialization of the AHCI (sata) subsystem. The following console output is
when booting and mounting the rootFS on uSD card:
What kernel are you using? I would probably try a 3.12.x kernel from
nodebug. The device tree support for the wandboard in 3.11 is
rudimentary at best and the uboot doesn't yet support booting off sata
so you'll still need a SD card with /boot and uboot on it.
