Hi,


   I am using the USB device port on my i.MX21(ARM 9) Lite kit. When I

plug in a flash drive, it gets detected perfectly as a storage device.

But I am not able to access the contents of the drive. When I mount

the drive, it says that the mount failed.


  dmesg:

Where are the SCSI disks? Did you load the sd driver?

I was also looking for the same. But I haven't built any of the

drivers as modules. All are built into the kernel. So I should really

see whether the SCSI driver is getting registered. Is everything fine

with the .config file? Or do I need to enable anything more?


Thanks,

Midhun.

Did you enable the partition type you are using on the device?

Please post the full dmesg.

By "partition type" you mean the file system? I have the FAT file

system enabled. The full dmesg is as below:

No, to use partitions you have to include support for the partitioning

scheme used.

Oh ! I do not know that. Where do I find out which scheme am I using?

fdisk should tell you whether you run the commonest scheme.

Hi,


   I have got the driver working by changing the .config.  The two

things that I have enabled are :


CONFIG_SCSI_TGT=y

CONFIG_SCSI_CONSTANTS=y


/ # cat /proc/devices

Character devices:

  1 mem

  2 pty

  3 ttyp

  4 /dev/vc/0

  4 tty

  4 ttyS

  5 /dev/tty

  5 /dev/console

  5 /dev/ptmx

  7 vcs

 10 misc

 13 input

 21 sg

 29 fb

 90 mtd

128 ptm

136 pts

180 usb

189 usb_device

253 usb_endpoint

254 usbmon


Block devices:

  1 ramdisk

  8 sd

 31 mtdblock

 65 sd

 66 sd

 67 sd

 68 sd

 69 sd

 70 sd

 71 sd

128 sd

129 sd

130 sd

131 sd

132 sd

133 sd

134 sd

135 sd

179 mmc


   I could find that CONFIG_SCSI_CONSTANTS is for verbose error

reporting. But CONFIG_SCSI_TGT ? Is this what has enabled the sd

driver? Can somebody explained what happened?


Thanks for all the help...

Midhun.

As far as I can tell, CONFIG_SCSI_TGT doesn't do anything at all for

simple setups like yours.  Maybe something else changed that you

weren't aware of.


For example, if you turn off CONFIG_SCSI_TGT and build the kernel

again, does everything still work?

I dont know what exactly has worked for me. But just for future

reference I would say that I have the following enabled on my 2.6.22

kernel:


SCSI device support

legacy /proc/scsi/ support

SCSI disk support

Probe all LUNs on each SCSI device


Thank you all for all the help !

Midhun.
