hi,

I reinstall all system including u-boot and file-system.
Now, I have these errors during booting.
Please advice.

Thats normal. Here's a technical answer that Nicolas Pitre told me:

Quote
Well... OK.  Those are probably caused by a lack of proper OOB
information.  Since your device has u-Boot actually booting the device
then the data in there is still fine.

To "fix" this, you could use the following commands:

[some commands removed for your safety]

and then Linux will be happy with 'cat /dev/mtdblock0 > /dev/null'.
Problem is that u-Boot becomes unhappy and ignores its env variable area
which is located at offset 0xa0000. If you set your u-Boot env variables
again and save them then it's Linux that becomes unhappy for data from
offset 0xa0000 again.

Trying to have u-Boot write itself with the bubt command in the hope
that the whole partition would have the same OOB data format all across
doesn't work any better as Linux then complains about errors right from
offset 0.  So I doubt the issue is specific to the SheevaPlug at this
point.

Don't try the commands, btw, because as the quote says, it doesn't fix it.

Just because of my curiosity I've tried the commands above. Now, my unit doesn't work at all. It happened after I've reboot it.
There is no message on the terminal window anymore.

Where would I do that?
Do I have to use another computer or my Sheeva plug.
I can't connect the Sheeva plug using serial port terminal anymore.
Do you have any Windows application that would upload the new firmware or u-boot image or maybe I can use an USB or CD card to boot form it?

Sevi4310,
  Have you tried pressing the reset button and then rebooting? I had a similar "can't get the mini-usb console to work" problem and that fixed it for me.

You need to do it under linux.
There's no application for windows that fixes the u-boot(for now). The only way is doing what that link says, or try what bfmorgan says as well.

The unit is completely dead. Reset button doesn't work. I think I erased u-boot.

I've installed Ubuntu to a regular computer and did steps form your instruction.

I've got all requierd files installed:
root@stockalerts:/usr/local/lib# ls /usr/lib/libftd2xx.so*
Config.txt  ftd2xx.cfg  libftd2xx0.4.16      libftd2xx.so.0.4.16  libusb-0.1.12  readme.dat  static_lib
faq.txt     ftd2xx.h    libftd2xx.so.0.4.12  lib_table            object         sample      WinTypes.h


Everything went well until I've got some errors:

after adding "none /proc/bus/usb usbdevfs defaults,mode=0666 0 0 " to /etc/fasttab I've got
root@stockalerts:~# mount -a
mount: unknown filesystem type 'usbdevfs'

And:
root@stockalerts:/usr/local/lib# /usr/lib/libftd2xx.so -> /usr/lib/libftd2xx.so.0
-bash: /usr/lib/libftd2xx.so: is a directory


Please advice.

-bash: /usr/lib/libftd2xx.so: is a directory


Please advice.

none /proc/bus/usb usbfs defaults,mode=0666 0 0 <- add this line instead the one you added.

Then you also need to do:
modprobe usbserial
modprobe ftdi_sio vendor=0x9e88 product=0x9e8f

Then follow the instructions on the wiki.

Afte I've changed fstab by your advice the command
"mount -a" doesn't give me an error anymore but
"modprobe usbserial" stil not working.
Take a look at the output below please.

I connected my Sheewa plug to my Ubuntu regular computer through USB - mini USB cable.
Computer connected by a regular USB, Sheeva - mini USB


root@stockalerts:~# mount -a
root@stockalerts:~# modprobe usbserial
FATAL: Module usbserial not found.
root@stockalerts:~# modprobe ftdi_sio vendor=0x9e88 product=0x9e8f

What does 'dmesg' say after you do those commands?
