RTOS/AM5726: ENETPHY_FindingState: Timed Out looking for a Phy

Hi Rasty,

The AM572x has two GMAC ports, in your case you only has PHY on the second RGMII and you want to skip the first one without break the EMAC driver code. We did this before. You can do is:

Keep this:

CSL_PUBLIC_CONST EMAC_Cfg EMAC_config[EMAC_NUM_MAX_MAC_PORTS] =

{

{

&EMAC_FxnTable_v4,

NULL,

&EMACInitCfg[0]

},

{

&EMAC_FxnTable_v4,

NULL,

&EMACInitCfg[0]

}

};

As both pointing to EMACInitCfg[0]:

EMAC_HwAttrs_V4 EMACInitCfg[1] =
{
{
SOC_CPSW_SS_REGS,
SOC_CPSW_MDIO_REGS,
SOC_CPSW_WR_REGS,
SOC_CPSW_ALE_REGS,
SOC_CPSW_CPDMA_REGS,
SOC_CPSW_CPPI_RAM_REGS,
SOC_CPSW_PORT_0_REGS,
SOC_CPSW_STAT_REGS,
GMAC_SW_IRQ_RX_PULSE_INT_NUM,
0,
GMAC_SW_IRQ_TX_PULSE_INT_NUM,
0,
EMAC_CPSW_CONFIG_MODEFLG_GIGABIT| EMAC_CPSW_CONFIG_MODEFLG_FULLDUPLEX,
2,
EMAC_RX_ISR_PER_MSEC_DEFAULT,
{
{
SOC_CPSW_PORT_1_REGS,
SOC_CPSW_SLIVER_1_REGS,
0U, =========> change this to EMAC_CPSW_NO_PHY_ADDR
},
{
SOC_CPSW_PORT_2_REGS,
SOC_CPSW_SLIVER_2_REGS,
1U,
}
}
}
};
