So can we configure the MAC on the ENC? The MAC address is fetched using am335x_evm.sh in /opt/scripts. Seems like it could be modified for if an adapter is detected in the kernel.
Aside, u-boot configures the on-board MII because the code was difficult to cut out. > On Oct 19, 2017, at 8:43 AM, Gerald Coley <[email protected]> wrote: > > MAC comes from the processor itself. > > > Gerald > > > > > On Thu, Oct 19, 2017 at 7:42 AM -0500, "Dan Brown" > <[email protected]> wrote: > >> I meant in the onboard EEPROM... >> >>> On Thursday, October 19, 2017 at 8:38:27 AM UTC-4, Dan Brown wrote: >>> I have noticed that both of my PocketBeagles have unique MACs that do not >>> move with the SD card when connecting via USB.
