 # Updating the firmware  ## Updating the kernel
   
 You probably don't want to do this. Firmware updates can break things,  
 and the latest firmware that's been tested is already included in the  
 NetBSD build you installed.  
   
 If you're feeling adventurous (or are the port maintainer), here's what  
 to test whenever you try new firmware:  
   
 - Audio  
 - OMXPlayer (and [[!template id=man name="vchiq"]])  
 - Serial/framebuffer console  
 - CPU frequency scaling  
   
 That goes for all of `rpi[0123]`.  
   
 Upstream firmware releases are  
 [on GitHub](https://github.com/raspberrypi/firmware/releases).  
 Copy all files except `kernel*.img` into `/boot` and reboot.
