booting BeagleBoneGreen

["John D. Baker" <jdbaker%mylinuxisp.com@localhost>]

Having convinced myself that the BeagleBoneGreen produced by Seeed is
equivalent to the BeagleBoneBlack--at least as far as devices supported
by NetBSD--I bought one along with the necessary accessories, namely the
3.3v FTDI USB UART cable.


Booting the pre-installed Linux presents a disk device:

Jan 11 19:57:08 skuld /netbsd: sd0: fabricating a geometry

but there is nothing recognizable to 'fdisk':

$ fdisk sd0           
fdisk: Cannot determine the number of heads

BIOS disk geometry:

Partition table:

No active partition.

'disklabel' just shows the default partitioning

The card is reachable via its ethernet connection and the web server
serves up the "Beagle 101" page.



Cribbing notes from OpenBSD, I set about netbooting the machine.  I
guessed that the "netbsd-BEAGLEBONE.ub" kernel was the correct one.  It
seemed that if anything encountered a problem along the way, the machine
would reset.  I fixed all the things I know I forgot, but the machine
still doesn't make it to launching 'getty' on the console.  It seems
that something is taking too long and the watchdog reset the board before
it can finish.
