Hi Guys,
I am using AM335x Processor. I am interfacing it with DP83867IRR Ethernet IC. I have enabled the driver in kernel.
The PHY ID is configured as 0;
# # MII PHY device drivers # CONFIG_AT803X_PHY=y CONFIG_AMD_PHY=y CONFIG_MARVELL_PHY=y CONFIG_DAVICOM_PHY=y CONFIG_QSEMI_PHY=y CONFIG_LXT_PHY=y CONFIG_CICADA_PHY=y CONFIG_VITESSE_PHY=y CONFIG_SMSC_PHY=y CONFIG_BROADCOM_PHY=y CONFIG_BCM7XXX_PHY=y CONFIG_BCM87XX_PHY=y CONFIG_ICPLUS_PHY=y CONFIG_REALTEK_PHY=y CONFIG_NATIONAL_PHY=y CONFIG_STE10XP=y CONFIG_LSI_ET1011C_PHY=y CONFIG_MICREL_PHY=y CONFIG_DP83848_PHY=y CONFIG_DP83867_PHY=y CONFIG_FIXED_PHY=y CONFIG_MDIO_BITBANG=y CONFIG_MDIO_GPIO=y CONFIG_MDIO_BUS_MUX=y CONFIG_MDIO_BUS_MUX_GPIO=y CONFIG_MDIO_BUS_MUX_MMIOREG=y CONFIG_MDIO_BCM_UNIMAC=y # CONFIG_MICREL_KS8995MA is not set # CONFIG_PLIP is not set
I have configured the DTS file as follows
&davinci_mdio {
pinctrl-names = "default", "sleep";
compatible = "ti,cpsw-mdio", "ti,davinci_mdio";
pinctrl-0 = <&davinci_mdio_default>;
pinctrl-1 = <&davinci_mdio_sleep>;
status = "okay";
dp83867_0: ethernet-phy@0 {
reg = <0>;
ti,rx-internal-delay = <DP83867_RGMIIDCTL_2_25_NS>;
ti,tx-internal-delay = <DP83867_RGMIIDCTL_2_75_NS>;
ti,fifo-depth = <DP83867_PHYCR_FIFO_DEPTH_4_B_NIB>;
ti,min-output-impedance;
ti,dp83867-rxctrl-strap-quirk;
};
};
&cpsw_emac1 {
phy_id = <&davinci_mdio>, <0>;
phy-mode = "rgmii-txid";
};
The Pin Mux is as follows
cpsw_default: cpsw_default {
pinctrl-single,pins = <
/* Slave 1 */
0x114 (PIN_OUTPUT_PULLDOWN | MUX_MODE2) /* mii1_txen.rgmii1_tctl */
0x118 (PIN_INPUT_PULLDOWN | MUX_MODE2) /* mii1_rxdv.rgmii1_rctl */
0x11c (PIN_OUTPUT_PULLDOWN | MUX_MODE2) /* mii1_txd3.rgmii1_td3 */
0x120 (PIN_OUTPUT_PULLDOWN | MUX_MODE2) /* mii1_txd2.rgmii1_td2 */
0x124 (PIN_OUTPUT_PULLDOWN | MUX_MODE2) /* mii1_txd1.rgmii1_td1 */
0x128 (PIN_OUTPUT_PULLDOWN | MUX_MODE2) /* mii1_txd0.rgmii1_td0 */
0x12c (PIN_OUTPUT | MUX_MODE2) /* mii1_txclk.rgmii1_tclk */
0x130 (PIN_INPUT | MUX_MODE2) /* mii1_rxclk.rgmii1_rclk */
0x134 (PIN_INPUT_PULLDOWN | MUX_MODE2) /* mii1_rxd3.rgmii1_rd3 */
0x138 (PIN_INPUT_PULLDOWN | MUX_MODE2) /* mii1_rxd2.rgmii1_rd2 */
0x13c (PIN_INPUT_PULLDOWN | MUX_MODE2) /* mii1_rxd1.rgmii1_rd1 */
0x140 (PIN_INPUT_PULLDOWN | MUX_MODE2) /* mii1_rxd0.rgmii1_rd0 */
>;
};
If I boot it shows the following during boot-up
[ 11.254589] net eth0: initializing cpsw version 1.12 (0) [ 11.261584] libphy: PHY not found [ 11.338490] net eth0: phy not found on slave 0 [ 11.403951] net eth0: phy found : id is : 0x2000a231
If I give dmesg | grep phy, Its giving output as follows,

If I give dmesg | grep DP83867

But the link is not up and the LED is not blinking.
Please Help !
