嘗試掛載usb,但是失敗囉~

7.解決minicom亂碼問題(家用主機一樣是ttyS0)
env LANG=env_US minicom -s
*A - Serial device : /dev/ttyS0
*E - (串口速度): 115200 bps,
8N1,
No,
No.

8.目標:順利在pxa300中mount MMC卡(32MB)
8.1.
把MMC卡放入pxa300中,不能順利mount
8.2.
於是把MMC卡用ubuntu的gparted格式化,卻沒想到越切越小(31MB到23MB)
8.3.
回到xp底下使用hp格式化工具把MMC卡還原成31MB(正常大小)
8.4.
到ubuntu的gparted工具格式化為ext2格式
8.5.
插入MMC卡的訊息:
[root@Linux /]#Device major:254, first minor:8

[root@Linux /]#cd /dev/mss/                                                    
[root@Linux mss]#ls

[root@Linux mss]#mount /dev/mss/blk1p1 /home/jim/mountsd/

[root@Linux mss]#cd /home/jim/mountsd/

sysfs                   /sys                    sysfs   defaults        0 0

/dev/mss/blk0 /home/jim/mountsd msdos defaults 0 0

8.6.fstab似乎不用去動他...總之成功了
