 It is not currently known how to emulate a RPI in qemu, and therefore anita does not yet have support for this.  \todo Add a command-line example to run qemu emulating some RPI model.  It is not currently known how to emulate a RPI in qemu, and therefore anita does not yet have support for this.  \todo Add a command-line example to run qemu emulating some RPI model.
   
   
   # Misc notes
   Miscellaneous notes about Raspberry PI.
   
   ## Power supply needed (or: why there is a little rainbow square in the top-right corner?)
   Raspberry Pi devices are powered by 5V micro USB and a 2.5A (2500mA)
   power supply is reccomended.  For more information please read:
   
    <https://www.raspberrypi.org/documentation/faqs/#pi-power>
   
   Power glitches can also manifest in other ways, e.g. with an USB
   disk plugged:
   
   [[!template id=programlisting text="""
   sd0(umass0:0:0:0): generic HBA error
   sd0: cache synchronization failed
   """]]
   
   Using a reccomended power supply avoid such issues.
   
   ## Xenon death flash (Raspberry Pi 2 is camera-shy)
   When using laser pointers or xenon flashes in cameras (or other
   flashes of high-intensity long-wave light) against a Raspberry Pi
   2 the Pi can power itself off.
