Ethernet issues on T4160RDB-64B Machine

[vinothkumars]

Dear NXP  Friends,

I am working Ethernet on T4160RDB-64B machine. I am unable to configure phy in dts file. Here I explain what I done in dts file and if I anything wrong please correct me.

Configure phy address in Serdes1 [SD1] and Serders2 [SD2]

Phy 0 connect with Serdes1 of Lane4 SD1 [4] 

Phy 1 connect with Serdes1 of Lane5 SD2 [5] 

Phy 17 connect with Serdes2 of Lane4 SD2 [4] 

Phy 19 connect with Serdes2 of Lane5 SD2 [5] 

In Dts file,

Hello vinothkumar s,

The memory map of fm2-mac9 is ffe5f0000-ffe5f0fff, the corresponding device node should be as the following.

enet14: ethernet@f0000 { /* FM2@TSEC9/FM2@TGEC1 */
            phy-handle = <&xfiphy3>;
            phy-connection-type = "xgmii";
};

The device node connecting to PHY 19 should be as the following,

      enet9: ethernet@e2000 {
               phy-handle = <&sgmiiphy42>;
               phy-connection-type = "sgmii";
};

Probably it is is fm2-mac2, please use "ifconfig -a" command to list all the Ethernet ports and check the Memory map.

fm2-mac2  Link encap:Ethernet  HWaddr 00:e0:0c:00:35:09
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
          Memory:ffe5e2000-ffe5e2fff

Please check whether the Ethernet port connecting to PHY 19 can work normally under u-boot.

Under u-boot, please type "=> mdio list" to check which Ethernet interface connecting to PHY 19, then configure u-boot environment variables "ethact" and "ipaddr" to check whether ping can work normally.

If your problem remains, please send you u-boot console log and dts file to me to do more investigation.

Thanks,

Yiping

Hi Yiping Wang,

Hi,

PHY detected successfully but unable to ping

=> mdio list
FSL_MDIO0:
0 - Marvell 88E1512 <--> FM1@DTSEC1      => able to access the phy and ping 
5 - Marvell 88E1322 <--> FM1@DTSEC3      => able to access the phy and unable to ping 
7 - Marvell 88E1322 <--> FM1@DTSEC4      => able to access the phy and unable to ping 
27 - Generic PHY <--> FM2@DTSEC4
FM_TGEC_MDIO:
0 - Generic 10G PHY <--> FM2@TGEC1

=> mii info
PHY 0x00: OUI = 0x5043, Model = 0x1D, Rev = 0x01, 10baseT, HDX
PHY 0x04: OUI = 0x5043, Model = 0x1C, Rev = 0x00, 10baseT, HDX
PHY 0x05: OUI = 0x5043, Model = 0x1C, Rev = 0x00, 1000baseT, FDX
PHY 0x06: OUI = 0x5043, Model = 0x1C, Rev = 0x00, 10baseT, HDX

What could be the issue? and I checked everything there is no MUX pin configuration  apart from RCW.

Hello vinothkumar s,

You need to modify the PHY addresses according to your custom board in u-boot.

Please refer to the following section in board/freescale/t4rdb/eth.c.
        if ((srds_prtcl_s1 == 28) || (srds_prtcl_s1 == 27)) {
                /* SGMII */
                fm_info_set_phy_address(FM1_DTSEC1, SGMII_PHY_ADDR1);
                fm_info_set_phy_address(FM1_DTSEC2, SGMII_PHY_ADDR2);
                fm_info_set_phy_address(FM1_DTSEC3, SGMII_PHY_ADDR3);
                fm_info_set_phy_address(FM1_DTSEC4, SGMII_PHY_ADDR4);
        } else {
                puts("Invalid SerDes1 protocol for T4240RDB\n");
        }

Please modify the SGMII PHY addresses according to your target board in include/configs/T4240RDB.h.

#define SGMII_PHY_ADDR1 0x0
#define SGMII_PHY_ADDR2 0x1
#define SGMII_PHY_ADDR3 0x2
#define SGMII_PHY_ADDR4 0x3
#define SGMII_PHY_ADDR5 0x4
#define SGMII_PHY_ADDR6 0x5
#define SGMII_PHY_ADDR7 0x6
#define SGMII_PHY_ADDR8 0x7
#define FM1_10GEC1_PHY_ADDR     0x10
#define FM1_10GEC2_PHY_ADDR     0x11
#define FM2_10GEC1_PHY_ADDR     0x12
#define FM2_10GEC2_PHY_ADDR     0x13

Have a great day,
TIC

Hi Yiping,

Thank you for your reply. I done the phy address configuration in u-boot as well as dts. One of the phy is working and this phy have the compatible driver and other phy are different and don't have the compatible driver.
