Bifferboard doesn't responding...

[Akio]

Hi,

yesterday I got my new bifferboard, but it isn't responding. I cannot
flash it with "python bb_eth_upload.py eth0 a1:b2:c3:xx:xx:f6 mp-bb-
image". Furthermore it isn't shown in my DHCP MAC list. I tried it
with a FritzBox and a DD-WRT Linksys WRT54G router.
What could I do? Should I resend it?

Thanks for your help!

The thing that most newcomers get wrong is that they have something in
between host running bb_eth_upload.py and the Bifferboard. This can
be a router, a faulty switch, some kind of NAT (Network Address
Translation), or a firewall. Look to see if any of your hosts are
running firewalls and disable them. The Bifferboard and
bb_eth_upload.py must both be able to see all packets on the network.

The Bifferboard doesn't register itself in DNS, and doesn't use DHCP,
so that's normal.

regards,
Biff.

Hi,

at first thank you very much for your fast answer! :-)
I've installed a fresh Ubuntu 8.04 Desktop Linux on my Desktop
computer with a deactivated firewall. For my flashing purposes I use
two patch-cables and a normal Netgear 8-Port switch with no Firewall
and no DHCP. Do I have to configure IP-settings for my linux computer?
Or how could I see, if the bifferboard isn't faulty? When I power it,
the blue LED is on and the yellow one is flashing very fast for about
30 seconds or so and after it, the yellow LED is on again. Is there a
possibility to ping this board or do another test?
Or what Linux distribution could you recommend?

Thank you very much for your support!

That setup should be OK.

You cannot ping the Bifferboard. The best way to figure out if you
have a faulty Bifferboard is to get the serial console cable:

or make your own:

You can return it, however if it's a problem with your network
configuration and the board is OK, we may charge to send it back to
you.

regards,
Biff.

Hi,

thank you for your support! Yesterday I got my original bifferos.co.uk
serial cable, but I actually have some problems by installing it under
Windows XP. How can I figure out, which chipset is in this cable? My
cable has a little box in the middle with a little switch. Do you
know, what I could do with that switch?
Nevertheless I think that my bifferboard is faulty, because I can't
see any red LED when it is connected to power and network. Is this
correct?

Thank you very much for your help!

Dunno, I only have the older (PL2303) cable ;)

The red LED is user-controllable, and doesn't come on by default. You
can either toggle it in the BiffBoot menus, or (after Linux has
loaded) you can manipulate it using GPIO SYSFS, e.g.
https://sites.google.com/site/bifferboard/Home/gpio (ignore the bit
about the kernel patch)

Dear Lurch,

thank you for your answer once again! I tried to install the CP2102
drivers and also the older PL2303 on a Windows XP and also on a
Windows 7 system, but it still doesn't work. The system always can't
find a driver for that cable. Does anyone now, what other driver I
could use or how I could solve my data cable problem? :-)

Thank you!

Modern Linux distributions tend to come with many different USB-serial
drivers already built-in, so I guess you could try booting your
computer from something like an Ubuntu Linux Live CD, and seeing if
your serial cable works with that?
