Enabling Ethernet in u-boot 2016-05 on AM335x

VLADIMIR ZHUKOV

We use TLK105RHBR Ethernet PHY.
The Ethernet PHY is connected to CPU via GMII1_XXX signals and uses external
clock (25MHz) which also connected to CPU as reference clock. PHY address is 1.
We are trying to enable Ethernet in u-boot 2016-05, but it does not work.

we have done following changes:

board.c"
//Before
if (board_is_bone() || board_is_bone_lt() ||
            board_is_idk()) {
                writel(MII_MODE_ENABLE, &cdev->miisel);
                cpsw_slaves[0].phy_if = cpsw_slaves[1].phy_if =
                                PHY_INTERFACE_MODE_MII;
        } else if (board_is_icev2()) {
                writel(RMII_MODE_ENABLE | RMII_CHIPCKL_ENABLE, &cdev->miisel);
                cpsw_slaves[0].phy_if = PHY_INTERFACE_MODE_RMII;
                cpsw_slaves[1].phy_if = PHY_INTERFACE_MODE_RMII;
                cpsw_slaves[0].phy_addr = 1;
                cpsw_slaves[1].phy_addr = 3;
        } else {
                writel((RGMII_MODE_ENABLE | RGMII_INT_DELAY), &cdev->miisel);
                cpsw_slaves[0].phy_if = cpsw_slaves[1].phy_if =
                                PHY_INTERFACE_MODE_RGMII;
        }

        ...

//After
if (board_is_bone() || board_is_bone_lt() ||
            board_is_idk() || board_is_costom()) {
                writel(MII_MODE_ENABLE, &cdev->miisel);
                cpsw_slaves[0].phy_if = cpsw_slaves[1].phy_if =
                                PHY_INTERFACE_MODE_MII;
                cpsw_slaves[0].phy_addr = 1;
        } else if (board_is_icev2()) {
                writel(RMII_MODE_ENABLE | RMII_CHIPCKL_ENABLE, &cdev->miisel);
                cpsw_slaves[0].phy_if = PHY_INTERFACE_MODE_RMII;
                cpsw_slaves[1].phy_if = PHY_INTERFACE_MODE_RMII;
                cpsw_slaves[0].phy_addr = 1;
                cpsw_slaves[1].phy_addr = 3;
        } else {
                writel((RGMII_MODE_ENABLE | RGMII_INT_DELAY), &cdev->miisel);
                cpsw_slaves[0].phy_if = cpsw_slaves[1].phy_if =
                                PHY_INTERFACE_MODE_RGMII;
        }

        ...
pinmux.c:
//Added

if (board_is_costum()) {
       configure_module_pin_mux(mii1_pin_mux);
       configure_module_pin_mux(mmc0_no_wp_pin_mux);
       configure_module_pin_mux(nand_pin_mux);
       configure_module_pin_mux(i2c1_pin_mux);
}

In DTS file the Ethernet configured following way:

But when we are doing ping or dhcp device can't connect to HOST.
Also we have tried to see packets with network sniffer and I do not see any ping
packets from device.

Please help to understand what we are doing wrong.

Hi Vladimir,

Have a look at the following threads:
e2e.ti.com/.../260419
e2e.ti.com/.../513709

Do you get any debug messages, when doint ping ? Can you share the console output?

Best Regards,
Yordan

Hi Vladimir,

Could you share your u-boot environment variables because it is possible to miss some important setting.

Dear Yordan,
Thank you for your reply.

The console log is:

Using ethernet@4a100000 device
ping failed; host 192.168.10.1 is not alive

Also I have added following debug print in driver/net/cpsw.c file:

static int _cpsw_send(struct cpsw_priv *priv, void *packet, int length)
{
void *buffer;
int len;
int timeout = CPDMA_TIMEOUT;

printf("DEBUG: _cpsw_send() -------------\n"); ///<-- Addedc debug print

As result when I doing ping I see this message in console,
but I can't see ARP (any) packets from my device to PC using Wireshark network sniffer application.

After that I have checked with oscilloscope MII RX/TX clocks , MII RX/TX data lines,
and MII TX EN signal results is following:

MII_RXCLK - 25Mhz clock
MII_TXCLK - 25Mhz clock
MII_RXDx - there are some data activity (it means data is coming from PHY to CPU)
MII_TXDx - there is no any data activity when I doing ping or dhcp command.
MII_TXEN - always is 0

So I think CPU not transmitting data to PHY via MII interface.

With Regards
Vladimir Zhukov

Vladimir,

Try to execute the steps described at:
www.emcraft.com/.../using-dhcp
Start ethernet capture before step 5. Post the output of step 5. Attach the ethernet capture if there is some packets.

I Have done and as result I do not see any packets coming from devices side to PC via Wireshark sniffer (but I mast see DHCP, ARP,ICMP and TFTPpackets).
below see log for console and Wireshark:

But when I making U-Boot for AM335x-EVM board and trying to this board I see on AM335x-EVM board DHCP working fine (in Wireshark I see DHCP,ARP,ICMP and TFTP packets.

I have resolved problem. The problem was in dts file.
I have done following changes on dts, which helped to solve the problem:

//Before
&mac {
active_slave = <1>;
pinctrl-names = "default", "sleep";
pinctrl-0 = <&cpsw_default>;
pinctrl-1 = <&cpsw_sleep>;

status = "okay";
};

&davinci_mdio {
pinctrl-names = "default", "sleep";
pinctrl-0 = <&davinci_mdio_default>;
pinctrl-1 = <&davinci_mdio_sleep>;

status = "okay";
};

&cpsw_emac0 {
phy_id = <&davinci_mdio>, <0>;
phy-mode = "mii";
};

&cpsw_emac1 {
phy_id = <&davinci_mdio>, <1>;
phy-mode = "mii";
};

//After

&mac {
active_slave = <0>; // -> select EMAC0.
pinctrl-names = "default", "sleep";
pinctrl-0 = <&cpsw_default>;
pinctrl-1 = <&cpsw_sleep>;

status = "okay";
};

&davinci_mdio {
pinctrl-names = "default", "sleep";
pinctrl-0 = <&davinci_mdio_default>;
pinctrl-1 = <&davinci_mdio_sleep>;

status = "okay";
};

&cpsw_emac0 {
phy_id = <&davinci_mdio>, <1>; // -> select PHY address 1.
phy-mode = "mii";
};
