partitions
SYNOPSIS
flashpart
kw/flashprep [ -vIWK ] [ -i plan9.ini ] [ -k kernel ] [ -e
erasesz ]
DESCRIPTION
These programs assist in dealing with on-board flash.
Flashpart uses the environment variable flashnpart to parti-
tion the flash device #Fn. The variable is formatted as a
sequence of partitions seperated by `/'. Each partition is
described by the space-seperated 3-tuple of name, start off-
set and end offset.
The flashprep tool builds a stand-alone bootable flash with
nvram, plan9.ini(8) and a kernel then emits a u-boot boot
command for the image and attempts to create the appropriate
partitions in #Fn. For ease of management, each element is
put in a seperate flash erase unit. The erase size is read
from #Fn but may be overridden with -e. The default config-
uration file is /cfg/pxe/ ea and may be changed with the -i
flag. The default kernel is /arm/9plug and may be changed
with the -k flag.
Partitions may be s With -I only plan9.ini is rewritten.
With -W only the nvram is rewritten.
