您好，

我希望通过 RGMII6实现两个 TDA4的直接 MAC2MAC 连接。 我根据 此常见问题解答中的配置进行了配置，但无法使用两个 TDA4相互 ping 通。

SDK 是 Linux + RTOS 7.1。

参考许多 E2E 线程，代码修改如下：

1. PINMUX 设置，J721E_PINMUX_DATA_GeSI_cpsw9g.c.

static pinmuxPerCfg_t gRgmii6PinCfg[] =
{
/* MyRGMII6 -> RGMII6_RD0 */
{
PIN_RGMII6_RD0, PIN_MODE(0) | \
((PIN_PULL_DISABLE | PIN_INPUT_ENABLE) & (~PIN_PULL_DIRECTION))
},
/* MyRGMII6 -> RGMII6_RD1 */
{
PIN_RGMII6_RD1, PIN_MODE(0) | \
((PIN_PULL_DISABLE | PIN_INPUT_ENABLE) & (~PIN_PULL_DIRECTION))
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

2.set RGMII 模式， board_Ethernet_config.c.

uint8_t portNum;
/* On J721E EVM to use all 8 ports simultaneously, we use below configuration
RGMII Ports - 1,3,4,5,6. QSGMII ports - 2 (main),7,8 (sub)*/
/* Configures the CPSW9G RGMII ports */
for(portNum=0; portNum < BOARD_CPSW9G_PORT_MAX; portNum++)
{

3.端口链路配置，ethfw.c.

EnetPhy_Cfg *phyCfg = &linkArgs->phyCfg;
CpswMacPort_Cfg *macCfg = (CpswMacPort_Cfg *)linkArgs->macCfg;
EnetMacPort_LinkCfg *linkCfg = &linkArgs->linkCfg;
EnetMacPort_Interface *mii = &linkArgs->mii;
uint32_t i;
CpswMacPort_initCfg(macCfg);
EnetPhy_initCfg(phyCfg);
/* PHY parameters from board specific code */
// EnetBoard_setPhyConfig(gEthFwObj.enetType,
// macPort,
// macCfg,
// mii,
// phyCfg);
if (ENET_MAC_PORT_6 == macPort)
{
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

4.no phy cfg，enet_apputils.c.
