* a PC/laptop running Windows or Linux or MacOS&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
You also need the following to run on ROCK Pi 4&lt;br /&gt;
&lt;br /&gt;
* ROCK Pi 4 board with power supply&lt;br /&gt;
* HDMI cable for display&lt;br /&gt;
* USB keyboard and mouse for input&lt;br /&gt;
  &lt;br /&gt;
== Boot To Maskrom Mode ==&lt;br /&gt;
