Project:Bifferboard

Bifferboard doesn't have working serial, so we need a distro that boots without asking.

Tried http://blog.famzah.net/category/bifferboard/ This can be done on Babbage (it has an autosensing ethernet card):

sudo ./bb_eth_upload.py eth0 00:b3:f6:00:35:c7 ../vmlinuz-2.6.30.5-bifferboard-ipipe

And everything else from there. Wouldn't boot:

VFS: Cannot open root device "<NULL>" or unknown-block(0,0)
Please append a correct "root=" boot option; here are the available partitions:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

Ditto for http://www.sunspot.co.uk/Projects/Bifferboard/Debian_distro.html:

Final result: Slackware works perfectly, without any trouble. Debian, does not. At all.

Not that any of this matters, as ms7821 fried the thing...

We now have three bifferboards (biffercluster will happen at some point)

Wiring through Bus Bandit

Bifferboard Bus Pirate

Connect BusPirate connector -> Black Grey Brown -> Yellow Green Black -> Bifferboard 9, 8, 7

(NB the blacks don't connect to each other)
