[参考译文] TDA4AL-Q1：DP83TG721 PHY 功能始终如一

在 reg (0x0F)上进行旁路检查 CAP、并更改  dp83tg720驱动器(dp83tg721_cs1_slave_init)中的数据后、它似乎已链接。

但是、仍然无法对 MCU 执行 ping 操作。

您好、Tanmay、

是的、我们以 enet RTOS lwip 示例 在 MCU 中提出 DP83TG721。

我已经在 examples\utils\v3\enet_board_j721s2_evm.c 中设置了速度和全双工

代码片段

static const EnetBoard_PortCfg gEnetCpbBoard_j7xEthPort[] =
{
    {    /* "MCU_ENET" */
        .enetType  = ENET_CPSW_2G,
        .instId    = 0U,
        .macPort   = ENET_MAC_PORT_1,
        .mii       = { ENET_MAC_LAYER_GMII, ENET_MAC_SUBLAYER_REDUCED },
        .phyCfg    =
        {
            .phyAddr         = 0x00U,
            .isStrapped      = BFALSE,
            .skipExtendedCfg = BFALSE,
            .extendedCfg     = &gEnetCpbBoard_dp83tg720PhyCfg,
            .extendedCfgSize = sizeof(gEnetCpbBoard_dp83tg720PhyCfg),
        },
        .sgmiiMode = ENET_MAC_SGMIIMODE_INVALID,
        .linkCfg   = { ENET_SPEED_1GBIT, ENET_DUPLEX_FULL },
        .flags     = 0U,
    },
};

另一个简短的问题、

Enet 示例中的 MAC 侧 RGMII Rx/TX 移位模式配置在哪里？

您好！

您是否可以尝试将"phyCfg"的"isStraped"属性设置为"BTRUE"而不是"BFALSE"。

我将在延迟配置上返回给您。

此致、
Tanmay

您好、Tanmay、

按照您的建议将"isStraped"更改为 true、并且 Phy 似乎卡在链接等待状态。  

static const EnetBoard_PortCfg gEnetCpbBoard_j7xEthPort[] =
{
    {    /* "MCU_ENET" */
        .enetType  = ENET_CPSW_2G,
        .instId    = 0U,
        .macPort   = ENET_MAC_PORT_1,
        .mii       = { ENET_MAC_LAYER_GMII, ENET_MAC_SUBLAYER_REDUCED },
        .phyCfg    =
        {
            .phyAddr         = 0x00U,
            .isStrapped      = BTRUE,
            .skipExtendedCfg = BFALSE,
            .extendedCfg     = &gEnetCpbBoard_dp83tg720PhyCfg,
            .extendedCfgSize = sizeof(gEnetCpbBoard_dp83tg720PhyCfg),
        },
        .sgmiiMode = ENET_MAC_SGMIIMODE_INVALID,
        .linkCfg   = { ENET_SPEED_1GBIT, ENET_DUPLEX_FULL },
        .flags     = 0U,
    },
};
