我用am3359的rmii2接口连接的lan8710a，配置的外置50M的有源晶振，
pinmux的设置
static struct module_pin_mux rmii2_pin_mux[] = {
{OFFSET(gpmc_a11), MODE(3) | RXACTIVE}, /* RMII2_RXD0 */
{OFFSET(gpmc_a10), MODE(3) | RXACTIVE}, /* RMII2_RXD1 */
{OFFSET(gpmc_wpn), MODE(3) | RXACTIVE}, /* RMII2_RXERR */
{OFFSET(gpmc_a0), MODE(3)}, /* RMII2_TXEN */
{OFFSET(gpmc_a5), MODE(3)}, /* RMII2_TXD0 */
{OFFSET(gpmc_a4), MODE(3)}, /* RMII2_TXD1 */
{OFFSET(gpmc_wait0), MODE(3) | RXACTIVE}, /* RMII2_CRS_DV */
{OFFSET(mii_col), MODE(1)}, /* RMII2_REFCLK */
{OFFSET(mdio_data), MODE(0) | RXACTIVE | PULLUP_EN},/* MDIO_DATA */
{OFFSET(mdio_clk), MODE(0) | PULLUP_EN}, /* MDIO_CLK */
{-1},
};
phy上面的决定phy_id的三个引脚全都下拉，phy_id应该是为0，
static struct cpsw_slave_data cpsw_slaves[] = {
{
.slave_reg_ofs = 0x208,
.sliver_reg_ofs = 0xd80,
.phy_id = 1,
},
{
.slave_reg_ofs = 0x308,
.sliver_reg_ofs = 0xdc0,
.phy_id = 0,
},
};
GMII_SEL配置为0x75，在uboot下执行dhcp还总是超时
link up on port 0, speed 100, full duplex
BOOTP broadcast 1
BOOTP broadcast 2
BOOTP broadcast 3
BOOTP broadcast 4
BOOTP broadcast 5
BOOTP broadcast 6
BOOTP broadcast 7
这是怎么回事，是我的配置有什么问题吗？rmii2的解法还有什么需要配置的吗
