Currently changing the Ethernet PHY on a board with a connect core 6ul
The original design has the same Ethernet arrangement as the starter kit using a lan8720
Its desired to connected a TI DP83848 in its place.
I have modified the device tree to reference a different phy
ethphy0: ethernet-phy@0 {
compatible = “ethernet-phy-ieee802.3-c22”;
dp83848;
reg = <0>;
};
also set CONFIG_DP83848_PHY=y in my defconfig.
compiled with latest dey (2.6-r2)
I have loaded the image onto the device and verified that the dp83848 has been compiled into the kernel drivers.
I get the error
fec 2188000.ethernet eth0: Unable to connect to phy
after boot.
Have i missed a step in the device tree for this to work? or are there any additional commands that can be run to debug connected devices?
Many Thanks
Phil
