&lt;p&gt;I am not familiar with how (if) others have done what you describe. One way to prevent images being flashed on the wrong device would be to use different keys for different HW versions, ensuring that a bad image is not flashed on the wrong device.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Best regards,&lt;br /&gt;Edvin&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
