Jason,
I did interrupt the boot process and type "run usbboot" to boot off USB.
Now I solved the problem by changing the usbboot env from:
usbboot=setenv bootargs console=ttyS0,115200 mtdparts=${partitions}
rootdelay=8 root=/dev/sda1; bootm fc000000
to
usbboot=setenv bootargs console=ttyS0,115200 mtdparts=${partitions}
rootdelay=8 root=/dev/sda1 rw; bootm fc000000
It seems like I have to explicitly to set "root=/dev/sda1 rw", or it will be
mounted as ro.
Thanks for all the help.
cheers,
Zhiwei
