Question: how to mount uclinux usb pen drive?help me.
 
uclinux-dev,
Hi,This is an letter asking for help in uclinux develepment.I use ucLinux-2.4.17.
I think my ucLinux has recogenized usb pen drive now. Following is the prompt. It can tell usb pen drive's attribute(e.g. position,id,size,version). But how can I read files in it? I can't mount it on.Help me,please.
Thanks.Longing for hearing from you.

Yours Sincerely,

This is your USB Pen. Linux Emulate it as SCSI, however you seem to have a problem with the partition table on it... corrupted data? Anyways.

try:
mkdir /mnt/usb_pen ;
mount /dev/sdc /mnt/usb_pen

chen_shannon 07-09-2003 09:30 PM
Yes,thank you,Half_Elf. It could work well a few days ago.
Below is what I have done in uclinux.
select kernel automount support in filesystem
select vfat support in filesystem
select dos partitions support in filesystem
"cat /proc/partitions" to find major & minor
mknod /dev/sdc b major minor
mount -t vfat /dev/sdc /cdrom
Thanks all. I think the forum is a good place for everyone.

Tommi 07-10-2003 02:41 AM
To be honest I decided to give up these pens, because they are not that what they should be...totally compatible in all machínes and platforms. Our helpdesk was really cynical with them.

I think they are on the early development phase, and industry is lacking a decent standard with them.

In the future there will be 40 gigabyte "pens" which are fully functional replacements for the excisting harddisks. It may take few years...but when this happens I will buy it again. Everybody does.

Never buy anything new...or you will become a product developer also.

Well...look at PC's! All what I see are only misfunctional prototypes...not ready systems. Wise men avoid them.

I wish there will be soon end for the speed competition. I really hope that the Moore's law soon will find its ceiling and speed cannot be improved then. Then starts the phase, that the systems must be developed to become fully functional...finally. But then we will get another problem...its life. :-)
