"rootwait" was there.
1. when I run "sudo ~/bin/mkefidisk.sh /dev/sda
core-image-sato-sdk-fri2-20130309091839.hddimg /dev/mmcblk0"
but "root=" was set to mmcblk0.
So I changed "root=" manually to sda2, usb is booted as well.
yes, I should have put the last parameter to be "/dev/sda" instead..
2. so when I run "sudo ~/bin/mkefidisk.sh /dev/sda
core-image-sato-sdk-fri2-20130309091839.hddimg /dev/sda"
USB is also working fine.
Thank you very much for the help, now I can use fri2 to test "meta-realtime"
