How to mount the u disk on omap3530

Other Parts Discussed in Thread: OMAP3530

I can mount the u disk, but it doesn't show the Chinese character correctly, instead of it is "?".

The operation is as follows :

1. mount the u disk on omap3530 by the command:

# mount /dev/sda1 /home/root/sd -t vfat

2. then get all of the file name which on the u disk by Qt's API.

3.  display them on the screen by Qt's widget.

(Qt is set  : QTextCodec::setCodecForLocale and QTextCodec::setCodecForTr with gb2312)

and I tried to add "-o iocharset=utf8" (same as cp936) for mount command and set Qt code as utf-8  but failed :

FAT: utf8 is not a recommended IO charset for FAT filesystems, filesystem will !
FAT: IO charset utf8 not found
mount: wrong fs type, bad option, bad superblock on /dev/sda1,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

What should I do?? It make me crazy now !!~~help~~plz~~

    Hi Fengyong,

    Could you specify the software version which you are using? List your boot args - it may be useful too.

    hi, Shulev

    Thanks for your reply.

    I don't use any software. I'm developing a software for omap3530, which tries to display the u disk's files on the screen. By the way, the software is developed by Qt. Before this, I use the command 'mount' to mount the u disk on /home/root/sd. The boot args are as follows:

    baudrate=115200
