Description:
 def boot(self, width=None, height=None, only_if_needed=True, check_booted=True, **boot_kwargs):
 """Boot a SpiNNaker machine. The system will be booted from the Ethernet connected chip whose hostname was given as the argument to the MachineController. With the default arguments this method will only boot systems which have not already been booted and will wait until machine is completely booted (and raise a :py:exc:`.SpiNNakerBootError` on failure). This method uses :py:func:`rig.machine_control.boot.boot` to send boot commands to the machine and update the struct files contained within this object according to those used during boot. .. warning:: Booting the system over the open internet is likely to fail due to the port number being blocked by most ISPs and UDP not being reliable. A proxy such as `spinnaker_proxy <https://github.com/project-rig/spinnaker_proxy>`_ may be useful in this situation. Parameters width, height : *Deprecated* **Deprecated.** In older versions of SC&MP, it was necessary to indicate the size of the machine being booted. These parameters are now ignored and setting them will produce a deprecation warning. scamp_binary : filename or None Filename of the binary to boot the machine with or None to use the SC&MP binary bundled with Rig. sark_struct : filename or None The 'sark.struct' file which defines the datastructures or None to use the one bundled with Rig. boot_delay : float Number of seconds to pause between sending boot data packets. post_boot_delay : float Number of seconds to wait after sending last piece of boot data to give SC&MP time to re-initialise the Ethernet interface. only_if_needed : bool If ``only_if_needed`` is True (the default), this method checks to see if the machine is already booted and only attempts to boot the machine if neccessary. If ``only_if_needed`` is False, the boot commands will be sent to the target machine without checking if it is already booted or not. .. warning:: If the machine has already been booted, sending the boot commands again will not 'reboot' the machine with the newly supplied boot image, even if ``only_if_needed`` is False. check_booted : bool If ``check_booted`` is True this method waits for the machine to be fully booted before returning. If False, this check is skipped and the function returns as soon as the machine's Ethernet interface is likely to be up (but not necessarily before booting has completed). Additional arguments used to override the default values in the 'sv' struct defined in the struct file. Returns ------- bool Returns True if the machine was sent boot commands, False if the machine was already booted. Raises ------ rig.machine_control.machine_controller.SpiNNakerBootError Raised when ``check_booted`` is True and the boot process was unable to boot the machine. Also raised when ``only_if_needed`` is True and the remote host is a BMP. Notes ----- The constants `rig.machine_control.boot.spinX_boot_options` can be used to specify boot parameters, for example:: controller.boot(**spin3_boot_options) This is neccessary on boards such as SpiNN-3 boards if the more than LED 0 are required by an application since by default, only LED 0 is enabled.
