Hi all,
In my case initially ethernet works on PHY Address 0 but in very rare scenario sometimes PHY address comes at 2.
My question is how to support for address 0 as well as Address 2 ? means whenever address changes to 2,ethernet should work,currently my Ethernet stops working when it comes at address 2
The PHY on the Beaglebone board apparently does not come up at address 0 on the MDIO control bus. From the previous power up tests, it seems to come up at address 2, possibly because of the way the PHY turns the configuration pins around at reset from inputs into outputs. When I previously discussed this with the application engineer from Micrel (PHY vendor), he suggested that maybe the software could automatically detect which address the PHY is on (like 0 or 1 or 2, etc.) and use that from then on instead if always being on address 0. I don’t know how feasible that is from a U-boot and Linux standpoint
kindly reply
