-==Notes==
-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:
- [    0.822178] usb usb2: Product: OHCI Host Controller
- [    0.827287] usb usb2: Manufacturer: Linux 2.6.32.2-bifferboard ohci_hcd
- [    0.827287] usb usb2: SerialNumber: 0000:00:0a.0
- [    0.838835] usb usb2: configuration #1 chosen from 1 choice
- [    0.846961] hub 2-0:1.0: USB hub found
- [    0.846961] hub 2-0:1.0: 2 ports detected
- [    0.856890] Initializing USB Mass Storage driver...
- [    0.856890] usbcore: registered new interface driver usb-storage
- [    0.871526] USB Mass Storage support registered.
- [    0.876429] VFS: Cannot open root device "<NULL>" or unknown-block(0,0)
- [    0.890057] Please append a correct "root=" boot option; here are the available partitions:
- [    0.898733] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

-'''Final result: Slackware works perfectly, without any trouble. Debian, does not. At all.'''
-<strike>Not that any of this matters, as ms7821 fried the thing...</strike>
-We now have three bifferboards (biffercluster will happen at some point)
-=== Wiring through Bus Bandit ===
-[http://bifferos.bizhat.com/pinouts/ Bifferboard] [http://wiki.hackspace.org.uk/wiki/BusPirate Bus Pirate]
-Connect BusPirate connector -> Black Grey Brown -> Yellow Green Black -> Bifferboard 9, 8, 7
-(NB the blacks don't connect to each other)
-Settings:
-UART, 115200, 8N1, Idle 1, 3.3V
-m 3, 9, [1], [1], [1], 2
-(then use macro (1) to enter UART bridge mode)
-== New attempt ==
-http://blog.famzah.net/2009/11/20/running-debian-on-bifferboard/
-SVN revision 238 required build-essential, libncurses5-dev (ncurses), kernel-package (make-kpkg), and took 3 hours to build on lovelace.
- svn co https://bifferboard.svn.sourceforge.net/svnroot/bifferboard bifferboard
- cd bifferboard/debian/
- ./build.sh 2.6.32
-The rootfs step requires debootstrap, and took 1 hour to build on lovelace.  The root password is hackspace.
- sudo su
- mkdir /mnt/biffo
- ./format-and-mount.sh /dev/sdb /mnt/biffo
- ./install-debian.sh /mnt/biffo/ uk
-Set up the [[BusPirate]] if you're using it:
- screen /dev/ttyUSB2 115200
- M
- (1)
-Space, Ctrl+A, :quit, Enter
-And finally, burn the loader:
- boot/bb_upload8.py /dev/ttyUSB2 /mnt/biffo/boot/vmlinuz-2.6.32-bifferboard
-When booting, hit Esc, and type
- usbroot
- save
- go
-as my Bifferboard attempted to boot without a commandline otherwise.
