# sshdkernel produces a kernel with a built-in initramfs for netboot
|
||||
# It provides (and starts) an sshd.
|

# ssh -i class_key -p 2022 board date

#
|

# The cpu image uses a cpud as its init, and you
|
||||
# can cpu to it to run commands.
|
||||
# to flash the flash image.
|
||||
# e.g.
|
||||
# cpu board date
|
||||
# cpu is way more convenient than ssh/scp if you can learn it.
|
||||
# you can also just
|
||||
# cpu board
|
||||
# NOTE: those commands are running on the board, and they all work
|

#
|

# You can test the flash image kernel with qemu

# make flashtest
