Revision as of 05:51, 24 July 2010

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)
