rootfs on usb drive

[aa305]

Is rootfs on usb at all possible (usb boot or rootfs on USB stick)? If so, can anyone share the method please.

Thanks

boot partition - no
root fs - yes

Kernel image and initrd file must be on SD, unless you have u-boot with USB support enabled and the u-boot is able to read from USB drive. But root partition may be on USB drive. It may be located on any drive visible by Linux. Root fs is specified in bootargs environment variable of u-boot and may be specified also on usb drive.
