Hello !
If you properly set the root fs on your USB flash you should try to
set it up using some uBoot bootargs :
e.g. :
setenv usbstick_args setenv bootargs root=/dev/sdXX ro
rootdelay=$HOW_MANY_SECONDS_TO_WAIT rootfstype=$YOUR_FS_TYPE
init=/sbin/init console=$consoledev,$baudrate;
setenv usbstick 'run usbstick_args;bootm fe500000 - fe700000'
setenv bootcmd run usbstick
Best !
