请问下能读到mac地址，但是检测不到网线的插入，dhcp服务起来后也分配不到IP，这是怎么回事？
网卡驱动的配置如下：
#define AM335X_EVM_PHY_ID 0x4dd072
#define AM335X_EVM_PHY_MASK 0xfffffffe
/* Module pin mux for rgmii1 */
static struct pinmux_config rgmii1_pin_mux[] = {
{"mii1_txen.rgmii1_tctl", OMAP_MUX_MODE2 | AM33XX_PIN_OUTPUT},
{"mii1_rxdv.rgmii1_rctl", OMAP_MUX_MODE2 | AM33XX_PIN_INPUT_PULLDOWN},
{"mii1_txd3.rgmii1_td3", OMAP_MUX_MODE2 | AM33XX_PIN_OUTPUT},
{"mii1_txd2.rgmii1_td2", OMAP_MUX_MODE2 | AM33XX_PIN_OUTPUT},
{"mii1_txd1.rgmii1_td1", OMAP_MUX_MODE2 | AM33XX_PIN_OUTPUT},
{"mii1_txd0.rgmii1_td0", OMAP_MUX_MODE2 | AM33XX_PIN_OUTPUT},
{"mii1_txclk.rgmii1_tclk", OMAP_MUX_MODE2 | AM33XX_PIN_OUTPUT},
{"mii1_rxclk.rgmii1_rclk", OMAP_MUX_MODE2 | AM33XX_PIN_INPUT_PULLDOWN},
{"mii1_rxd3.rgmii1_rd3", OMAP_MUX_MODE2 | AM33XX_PIN_INPUT_PULLDOWN},
{"mii1_rxd2.rgmii1_rd2", OMAP_MUX_MODE2 | AM33XX_PIN_INPUT_PULLDOWN},
{"mii1_rxd1.rgmii1_rd1", OMAP_MUX_MODE2 | AM33XX_PIN_INPUT_PULLDOWN},
{"mii1_rxd0.rgmii1_rd0", OMAP_MUX_MODE2 | AM33XX_PIN_INPUT_PULLDOWN},
{"mdio_data.mdio_data", OMAP_MUX_MODE0 | AM33XX_PIN_INPUT_PULLUP},
{"mdio_clk.mdio_clk", OMAP_MUX_MODE0 | AM33XX_PIN_OUTPUT_PULLUP},
{NULL, 0},
};
am33xx_cpsw_init(AM33XX_CPSW_MODE_RGMII, "0:06", "0:04");
/* Atheros Tx Clk delay Phy fixup */
phy_register_fixup_for_uid(AM335X_EVM_PHY_ID, AM335X_EVM_PHY_MASK,am33xx_evm_tx_clk_dly_phy_fixup);
原理图如下：红线部分是有连接的地方
还请问下 am33xx_cpsw_init(AM33XX_CPSW_MODE_RGMII, "0:06", "0:04");中的“0:06”和“0:06”是什么意思？我看有的sdk中的phy_id是整形的，为ACT ，RXD1，RXD0三位的一个值，这里是字符串是什么含义？
在uboot下不正确配置网卡有关系吗？在uboot下不使用网络的情况下；
谢谢
