Hi,

I am still trying to get a helloworld program up and running on linux!

I have installed the linux_demo from Atmel/TimeSys.

Since I don't have an ICE and the eth0 does not work with the linux demo, I am trying to transfer my helloworld program onto the file system using a USB stick with the file on.

It seems to recognise when I connect/disconnect the USB stick (from some daemon output), but when I attempt to mount it I get the following result:

# mkdir /mnt/usb-stick
# mount /dev/sda /mnt/usb-stick/
mount: Mounting /dev/sda on /mnt/usb-stick/ failed: No such device or address

I get this with all sda1, sda2, ...sdb, sdb1, ...etc. it seems.

Can anyone tell me what Im doing wrong.

Cheers,
Tom

copy the dmesg output, too.
The usb stick may have either just a FAT filesystem on it or a partition with FAT filesystem(more common). So usually, you should mount /dev/sda1

Hyperterminal Output:

# mkdir /mnt/usbstick
# mount /dev/sda1 /mnt/usbstick
mount: Mounting /dev/sda1 on /mnt/usbstick failed: No such device or address
# (pulling out usb stick now...)

but dmesg? excecute dmesg command from shell and copy output, please.

Sorry, I misunderstood..

Do you have the sda, sda1 device nodes at /dev?
Has your kernel SCSI disk support and usb mass storage support turned on at all?

try to excecute

when the usb flash is inserted.

try

to check if the dev nodes are there and the major/minor numbers are correct.

The 2.6.18-rc4 kernel is really old (when considering the fast development of AT91), so you should definitely consider recompiling your kernel from some later version (I develop on the latest 2.6.23-rc5 at the moment - the 2.6.23 will go stable probably before my product release date). So I recommend you using the latest kernel with the latest extra AT91 patches from http://maxim.org.za/at91_26.html .

You probably need to create the device node.



Also, mount with the -t vfat option, otherwise it mangles the filenam~1.

Also, build your own kernel, you'll almost surely need to do it eventually. See the threads about Buildroot.

1.Need make sure Kernel can support SCSI
2.Need make sure kernel can support VFAT
3.Need enable CRC_T10DIF set to yes
4.Need mount with -t vfat
