AM335x用DP83865

您说的是哪个板子，最新的uboot里面有对phy的支持，但是目前是对EVM板上的phy的支持。

如何修改，你可以对照着uboot或者kernel中的driver通过mdio配置phy了

谢谢您的回答，

我在uboot里修改软件使得能够支持，

"writel(RGMII_MODE_ENABLE,MAC_MII_SEL);

cpsw_data.gigabit =1"

但是还是不能工作。

在U-boot里运行DHCP

打印如下：

“Retry count exceeded; starting again

phyid1 = 0x2000

phyid1 = 0x5c7a

phy name =cpswAuto Negotitation failed for port 0

BOOTP broadcast 1

BOOTP broadcast 2

BOOTP broadcast 3

BOOTP broadcast 4

BOOTP broadcast 5

BOOTP broadcast 6

BOOTP broadcast 7

BOOTP broadcast 8

BOOTP broadcast 9

BOOTP broadcast 10”

看样子phyid是能够找到了，但不知还需要改哪里才能工作！谢谢！

这个你参考下kernel里面的驱动吧

我用最新2011.08-PSP.04.06.00.08，

linux kernel也是不能工作

在uboot下，运行DHCP命令

我的uboot下的pin mux：

static struct module_pin_mux rgmii1_pin_mux[] = {

        {OFFSET(mii1_col ), MODE(2)},                   /* RGMII1_COL */
        {OFFSET(mii1_crs),  MODE(2)},                   /* RGMII1_CRS */
        {OFFSET(mii1_rxerr), MODE(2)|RXACTIVE},         /* RGMII1_RXERR */

        {OFFSET(mii1_txen), MODE(2)},                   /* RGMII1_TCTL */
        {OFFSET(mii1_rxdv), MODE(2) | RXACTIVE},        /* RGMII1_RCTL */
        {OFFSET(mii1_txd3), MODE(2)},                   /* RGMII1_TD3 */
        {OFFSET(mii1_txd2), MODE(2)},                   /* RGMII1_TD2 */
        {OFFSET(mii1_txd1), MODE(2)},                   /* RGMII1_TD1 */
        {OFFSET(mii1_txd0), MODE(2)},                   /* RGMII1_TD0 */
        {OFFSET(mii1_txclk), MODE(2)},                  /* RGMII1_TCLK */
        {OFFSET(mii1_rxclk), MODE(2) | RXACTIVE},       /* RGMII1_RCLK */
        {OFFSET(mii1_rxd3), MODE(2) | RXACTIVE},        /* RGMII1_RD3 */
        {OFFSET(mii1_rxd2), MODE(2) | RXACTIVE},        /* RGMII1_RD2 */
        {OFFSET(mii1_rxd1), MODE(2) | RXACTIVE},        /* RGMII1_RD1 */
        {OFFSET(mii1_rxd0), MODE(2) | RXACTIVE},        /* RGMII1_RD0 */
      //{OFFSET(mii1_refclk), MODE(2)|RXACTIVE},                 /* RGMII1_REFERR */
        {OFFSET(mdio_data), MODE(0) | RXACTIVE | PULLUP_EN}, /* MDIO_DATA */
        {OFFSET(mdio_clk), MODE(0) | PULLUP_EN},        /* MDIO_CLK */
        {-1},
};

Auto Negotitation failed for port 0 说明什么问题呢？

出现Auto Negotitation failed for port 0，是因为没有使能A/N enable。

但还是ping不通。

linux下也是ping不通的。

我也遇到和你差不多的问题了哈

请问应用DP83865，AM3358实现网口通信，我现在用starterware裸跑例程，需要进行哪些配置的修改啊？如跑enetEcho，谢谢
