我用6410挂载USB光驱，插入时，
scsi 2:0:0:0: CD-ROM            HL-DT-ST DVDRAM GSA-4084N KQ09 PQ: 0 ANSI: 0
s3c2410-ohci s3c2410-ohci: urb ccd1f880 path 1.3 ep1in 93120000 cc 9 --> status -121
sr0: scsi3-mmc drive: 24x/24x writer dvd-ram cd/rw xa/form2 cdda tray
sr 2:0:0:0: Attached scsi CD-ROM sr0
sr 2:0:0:0: Attached scsi generic sg0 type 5

中表明已连接到/dev/sr0下，但怎么都挂载不上，求各位帮忙。我使用mount -t iso9660 /dev/sr0 /mnt/cdrom 出现
mount: mounting /dev/sr0 on /mnt/cdrom/ failed: No such device
应该输入哪个参数啊

我想你可以用cat /proc/partitions看看输出里面是否包括sr0, 另外，你能贴出mount失败之后dmesg命令的输出吗？

[root@FriendlyARM ~]# cat /proc/partitions
major minor  #blocks  name

  31        0        512 mtdblock0
  31        1       5120 mtdblock1
  31        2     256512 mtdblock2

使用直接mount 后出现的
[root@FriendlyARM /dev]# mount /dev/sr0 /mnt/cdrom/

我在ubuntu linux系统，同样是挂载sr1 就可以挂载上。信息如下:

[33280.646238] scsi 9:0:0:0: CD-ROM            HL-DT-ST DVDRAM GSA-4084N KQ09 PQ: 0 ANSI: 0

使用命令:

harry@harry-desktop:/media$ sudo mount -t iso9660 /dev/sr1 /media/cdrom
mount: 块设备 /dev/sr1 写保护，已只读方式挂载

是不是6410内核的mount 命令未移植好呢

已经可以了，内核没有支持iso9660文件系统，但现在又有一个问题，挂载数据cd就可以，如果是音频cd就挂载不上，

也许你可以在PC的Ubuntu系统上挂载音频CD后用mount命令看看具体用的是什么文件系统。

音频cd不是文件系统来的，不用mount,请问有人知道怎么抓轨吗,我看了,是cdda文件系统来的
