Hi all,
I'm attempting to mount the root file system directly from a USB flash stic=
k (thus avoiding a ram-disk). The init thread is delayed until the USB devi=
ce is enumerated. However, I find the call to sys_mount() in line 218 @ htt=
p://git.denx.de/?p=3Dlinux-2.6-denx.git;a=3Dblob;f=3Dinit/do_mounts.c;h=3D8=
d4ff5afc1d80b56963cbf119b162a3ebce61124;hb=3Dad2a8c8d0593bf2d1ef163f1ca7574=
f02b2e770e fails. The problem is I can't work out where sys_mount() is impl=
emented.
I'm working off the 2.6.29-DENX kernel (commit id ad2a8c8d0593bf2d1ef163f1c=
a7574f02b2e770e). and My target CPU is an
mpc8349.
Thanks in advance.

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 !
