Please have your email client wrap lines after 75 columns or so. It's
rather inconvenient to deal with messages where each paragraph is just one
very very long line...
----------------------------------------------------------------
Sorry about that but that's because excite is a horrible email and I
have to wrap it myself. I oftentimes forget and thats what you saw.
You will also see "---" between replys and that's also why.
-------------------------------------------
Is that different from simply using the device as a normal flash drive?
How do you know the device uses NOR Flash, and what difference does it
make what type of flash the device contains?
----------------------------------------
Perhaps you misunderstood me. I refer NOR flash to refer to local (system)
flash in contrast to USB flash drives which is external.
-------------------------------------------------
What exactly do you mean by "recognizes"? What does the dmesg log say?
----------------------------------
Yes, recognize meaning "dmesg".
-------------------------------------------------
Assuming your distribution is reasonably up-to-date, the device node will
be created for you automatically. If it isn't then it's an indication
that the kernel is _not_ fully recognizing the flash drive.
--------------------------------------------------
Sorry again, I failed to mension I'm working on an embedded platform
working with a filesystem I created and not one of the typical desktop
distribution (That would be an easy solution).

It depends on what software you are using. If you have an automounter
running then it would mount the device for you; otherwise you would have to do
it yourself.

You can find out for yourself very easily by looking at the udev log.
(You may have to use udevcontrol to increase the amount of information
sent to the log file.)
--------------------------------------------------
Because I'm on an embedded platform I don't have udev and from what I've picked
up so far It looks like I'll have to write a script to take care of these
things myself if I know what signals to receive once the usb flash drive is
connected.
I don't expect the kernel to mount any filesystem for me, however, I trying to
find out how this soft of thing is done with all the usb work that's been done
so far that has been integrated in the kernel.
The idea here is to use the usb flash drive to update a local flash image on an
embedded device (ARM9 device in this case).
