AM6548: CPSW (RMII) + DP83822

Hi TI Team,

Does the latest Linux sdk support to config CPSW with RMII mode?

We use CPSW with RMII interface to DP83822 PHY on our custom board.

The SDK I use is ti-processor-sdk-linux-rt-am65xx-evm-07_00_01_07.

The Link Up/Down state is working well.

But I can't ping to PC successfully....

The dts as below

mcu_cpsw_pins_default: mcu_cpsw_pins_default {
pinctrl-single,pins = <
AM65X_WKUP_IOPAD(0x0058, PIN_OUTPUT, 1) /* (N4) MCU_RGMII1_TX_CTL.MCU_RMII1_CRS_DV */

#define TS_OFFSET(pa, val) (0x4+(pa)*4) (0x80000000 | val)

&timesync_router {
pinctrl-names = "default";
pinctrl-0 = <&mcu_cpts>;

/* Example of the timesync routing */
mcu_cpts: mcu_cpts {
pinctrl-single,pins = <
/* pps [cpts genf1] in13 -> out25 [cpts hw4_push] */
TS_OFFSET(25, 13)
>;
};
};

Any suggestion?

Thanks
