MAC comes from the processor itself.

(I tried switching the cards between PBs and the MACs stay with the boards.) Could it be something in the onboard flash?

I wonder if it is possible to populate it with the same one that the USB Ethernet interface uses when attaching to a PC. I haven't looked but my guess is there is a MAC address burned into the processor. --steve On Wednesday, October 18, 2017 at 8:36:58 AM UTC-5, Graham wrote: I have gotten an additional two MAC addresses (total five, now) presented by the ETH-WIZ. (So, it has appeared on five different IP addresses in my network, and I can't give it a static address, since that is paired with the MAC address.) It never changes while running, and usually not when rebooting, but will almost always change the MAC address after loading a new image on the PB. And none of them are 'legal'. (That is, no recognizable OUI identifying the manufacturer.) There must not be a memory for the MAC address in the ETH-WIZ, and the driver makes one up using a random number generator, upon booting on a new image for the first time. I am tired of chasing this Ethernet interface all over my network address space. . --- Graham == -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
