Debricking one Bifferboard from another

I've done the usual minimal testing with it, it works, but I suggest
you only use it if you have a brick, or possibly if you have an NAS
dongle that's based on the same RDC chip and want to run Linux on it.

BIOS upgrade 'utility'

You can now upgrade your BIOS relatively easily (without JTAG).

I suppose I don't need to say this, but I will anyhow: USE ENTIRELY
AT YOUR OWN RISK! This is a convenience utility for people who can't
be bothered to get their JTAG cable out the drawer to try out a new
version of Biffboot. Noobs, please get your friend to do it, and then

detect the flash and work for 1, 4 and 8MB devices. I think some
devices that we shipped did have MX (not EON) flash devices, and I
believe that the detection code won't work for those. If anyone wants

Hi, I know I'm late too the party. Just finding the device when business

My company will still release products based on the Bifferboard, mostly
due to the investment we have put in our product (and problems finding a
hardware replacement). I have contacted the manufacturer and made a

2012-11-08T19:15:47Z

Hi, I've been using the Bifferboard for some months now, and I'm very
satisfied with the device. I started out with kernel 2.6.32 with adapted
patches from 2.6.30.5-biff. I "ported" the patches I used from .32 to
3.0 (.32 had some minor issues), and things seems to work ok (at least
what I use the device for). I've included them here if someone needs

So do I get 4x48v PSUs, 4x injectors/splitters, 4x 48v->5v buck regulators?
Or would I be better off doing this at 24v over the wire which may make the
