# This is the makefile for a flash image, a netbootable sshd image,
|
||||
# and a netbootable cpu image.
|
||||
#
|
||||
# sshdkernel produces a kernel with a built-in initramfs for netboot
|
||||
# It provides (and starts) an sshd, and also has flashrom.
|
||||
# Hence you can ssh to a node, flashrom -r on it, scp the
|
||||
# image back, process it, scp the new image to the node, and
|
||||
# write with flashrom.
|
||||
# e.g.
|
||||
# ssh -i class_key -p 2022 board flashrom -r image.bin -p internal
|
||||
# scp -i class_key -P 2022 board:/image.bin image.bin
|
||||
# make tiny.bin
|
||||
# scp -i class_key -P 2022 tiny.bin board:/tiny.bin
|
||||
# ssh -i class_key -p 2022 board flashrom -w tiny.bin -p internal
|
||||
#
|
||||
# The cpu image uses a cpud as its init, and you
|
||||
# can cpu to it to run commands, including flashrom -p internal
|
||||
# to flash the flash image.
|
||||
# e.g.
|
||||
# cpu board flashrom -r image.bin -p internal
|
||||
# Note this writes image image.bin to the host directoy; no scp needed
|
||||
# make tiny.bin
|
||||
# cpu board flashrom -w tiny.bin -p internal
|
||||
# cpu is way more convenient than ssh/scp if you can learn it.
|
||||
# you can also just
|
||||
# cpu board
|
||||
# and once you are in:
|
||||
# flashrom -r image.bin -p internal
|
||||
# make tiny.bin
|
||||
# flashrom -w tiny.bin -p internal
|
||||
# NOTE: those commands are running on the board, and they all work
|
||||
#
|
||||
# You can test the flash image kernel with qemu
|
||||
# make flashtest
