Hello all,
I am trying to bring the ethernet Interface up on our custom board(i-MX6 solo) which is based on sabresd schematics.But we are using different Ethernet PHY (LAN 8740A) from SMSC .I added the driver as built-in in the kernel.The PHY address we configured is 000.When I boot the kernel logs regarding Ethernet are as follows:
Configuring network interfaces... fec 2188000.ethernet eth0: Freescale FEC PHY driver [Generic PHY] (mii_bus:phy_addr=2188000.ethernet:00, irq=-1)
IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready
done.
Starting Dropbear SSH server: libphy: 2188000.ethernet:00 - Link is Up - 10/Half
IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
dropbear.
fec 2188000.ethernet eth0: Graceful transmit stop did not complete!
libphy: 2188000.ethernet:00 - Link is Down
The pad settings and the node for ethernet are as follows:
&fec {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_enet>;
phy-mode = "mii";
phy-reset-gpios = <&gpio7 12 0>;
//phy-supply = <®_fec_supply>;
phy-handle = <ðphy>;
fsl,magic-packet;
status = "okay";
mdio {
#address-cells = <1>;
#size-cells = <0>;
ethphy: ethernet-phy@0 {
compatible = "smsc,lan8740";
device_type = "ethernet-phy";
reg = <0>;
};
};
pinctrl_enet: enetgrp {
fsl,pins = <

};
But the Problem is that SMSC PHY is not getting attached and I am unable to bring the Ethernet up.
So if anyone have suggestions to solve this issue then Please share it
