 # Board specific notes  # MAC address
   
 ## Merrii Hummingbird A31  On boards where the ethernet MAC address cannot be determmined, a random MAC address will be generated every boot. You can override this behaviour by specifying a MAC address in *uEnv.txt*:
   [[!template  id=filecontent name="uEnv.txt" text="""
 There doesn't appear to be a meaningful way to generate a MAC address on these boards. U-Boot from the A31 SDK and from the u-boot-sunxi tree both lack GMAC support, and the Security ID registers (at 0x01c23800) appear to be empty.  
   
 To overcome this, you can specify your own MAC address in *uEnv.txt*:  
 [[!template  id=programlisting text="""  
 bootargs=root=ld0a awge0.mac-address=02:a0:3d:88:1a:1e  bootargs=root=ld0a awge0.mac-address=02:a0:3d:88:1a:1e
