imx7d with ar8035 can not work

[xing]

I am using IMX7D with AR8035 PHY in my own custom board.

Now I met one problem. When I want ping the  board with PC, can transmit but can not receive any data.

the board boot log is in attachment, please give some advice.

the kernel file, DTS and mach-imx7d.c , SCHEMATIC  are also in attachment.

Thanks a lot!

Now fec0 is ok if I change uboot board file.and it will not need mii info cmd any more.

The fec part in uboot file

If  I delete  //imx_iomux_v3_setup_multiple_pads(phy1_rst_pads, ARRAY_SIZE(phy1_rst_pads));

then it will be ok. but the uboot log will send message :

Net: Phy 2 not found

PHY reset timed out

What's wrong?

FEC0 dose not work in boot now and before.

The dts file is seems to be ok now. 

[BiyongSUN]

Sugget you can use the DTS to try. 
You can debug in the following API to see if the GPIO really get and reset the  phy.
Also please measure by oscilloscope.

fec_main.c

static void fec_reset_phy(struct platform_device *pdev)
{
 int err, phy_reset;
 int msec = 1;
 struct device_node *np = pdev->dev.of_node;

 if (!np)
  return;

 err = of_property_read_u32(np, "phy-reset-duration", &msec);
 

/* A sane reset duration should not be longer than 1s */
 if (!err && msec > 1000)
  msec = 1;

 phy_reset = of_get_named_gpio(np, "phy-reset-gpios", 0);
 if (!gpio_is_valid(phy_reset))
  return;

 err = devm_gpio_request_one(&pdev->dev, phy_reset,
        GPIOF_OUT_INIT_LOW, "phy-reset");
 if (err) {
  dev_err(&pdev->dev, "failed to get phy-reset-gpios: %d\n", err);
  return;
 }
 msleep(msec);
 gpio_set_value(phy_reset, 1);
}
#else /* CONFIG_OF */
static void fec_reset_phy(struct platform_device *pdev)
{
 /*
  * In case of platform probe, the reset has been done
  * by machine code.
  */
}

I also seet  the following statement in the imx7d-wiseiot.dts

&iomuxc_lpsr {
 
pinctrl-names = "default";
 
pinctrl-0 = <&pinctrl_enet_refclk>;

 
imx7d-pico-miscpins {
  
pinctrl_enet_refclk: enet_refclk {

see the MX7D_PAD_UART3_RX_DATA__GPIO4_IO4    
fsl,pins = <
    
MX7D_PAD_GPIO1_IO01__CCM_ENET_REF_CLK3  0x1 
 

pinctrl_enet1: enet1grp {
   
fsl,pins = <
    
MX7D_PAD_GPIO1_IO10__ENET1_MDIO  0x3
    
MX7D_PAD_GPIO1_IO11__ENET1_MDC  0x3
                               
MX7D_PAD_UART3_RX_DATA__GPIO4_IO4  0x3

Suggest to use a clean DTS from NXP BSP to try.

I reviewed the schematic Ethernet1.pdf. For usinng ar8035 hardware design.

Please refer to the the hardware design for dual ethernet ar8031 in i.MX6SX. Please pay attention to the connections of clocks.

It should use the i.MX output for ar8035 or  using ar8035 for feeding i.MX clock.

In the i.MX6SX has those options.

Hi, Biyong Sun

I have rework the board, and set fec1 phy_id is to 2.

dts file add

phy-reset-duration = <10>;

the board still need mii info uboot  cmd .

now the log ,  the uboot board file and dts file.

First of all, in your log, the pin has confilct for eth0.

In the uboot, the clock is shared.

So please reset the phy in the kernel by gpio.

You can refer to the binding guide  Documentation\devicetree\bindings\net\fsl-fec.txt

- phy-reset-gpios : Should specify the gpio for phy reset
- phy-reset-duration : Reset duration in milliseconds.  Should present

The conflict in your log:

Hi, Biyong Sun

Thank you reply. I have test by changing phyid at 0x02, but it does not work.

And now the fec2 is ok in kernel .

When I use the mii info cmd in uboot  and then boot the kernel, the fec1 can work now.

If there is no mii info cmd, the fec1 will not work.

The fec1 phy id is still 0  now.

So we can fix the problem on software. I miss somthing in kernel?  Please help me!

=> mii info

PHY 0x04: OUI = 0x1374, Model = 0x07, Rev = 0x02, 10baseT, HDX

If you don't define the phyid as the BSP release, it will do the autoscan from phyid 0. But in you hardward design the 0 should be the broadcast PHY address not  unique PHY address..

The phy address is defined by "hardware". Please check the hardware design then make it in dts.

You log shows you are using the autoscan. And the 0 phyid is got.

So I provided the two ways in the previous reply. One is to use dts to define, of course according to the hardware design.

If not define the phyid in the dts to use the autoscan. Make changes in the kernel C code, to scan from 1 not 0.

It is the same in the uboot. and you will see the phyid in the result. and the software will automatically set the phyid for you.  

For the uboot,

1. so far, it doesn't support two ethernet interface. It is not neccessary to support two ethernet interfaces in uboot.

2.   also you can use  and certain address for the mii info  command: mii info   <addr>                     - display MII PHY info

3. In the hardware design, you can make PHY Address 0 set as unique PHY address. Broadcast phy address 0 is not used under your case.

4. If you cannot re-work the hardware, you can make the mirror change as it is in the Linux kernel.

    To scan from 1 not 0.

uboot-imx\common\miiphyutil.c

void mdio_list_devices(void)
{
 struct list_head *entry;

 list_for_each(entry, &mii_devs) {
  int i;
  struct mii_dev *bus = list_entry(entry, struct mii_dev, link);

  printf("%s:\n", bus->name);

 //for (i = 0; i < PHY_MAX_ADDR; i++) {

  for (i = 1; i < PHY_MAX_ADDR; i++) {
   struct phy_device *phydev = bus->phymap[i];

   if (phydev) {
    printf("%d - %s", i, phydev->drv->name);

    if (phydev->dev)
     printf(" <--> %s\n", phydev->dev->name);
    else
     printf("\n");
   }
  }
 }
}

In the previous reply:

For the kernel

fec_main.c：

{
 struct fec_enet_private *fep = netdev_priv(ndev);
 struct phy_device *phy_dev = NULL;
 char mdio_bus_id[MII_BUS_ID_SIZE];
 char phy_name[MII_BUS_ID_SIZE + 3];
 int phy_id;
 int dev_id = fep->dev_id;

 fep->phy_dev = NULL;

 if (fep->phy_node) {
  phy_dev = of_phy_connect(ndev, fep->phy_node,
      &fec_enet_adjust_link, 0,
      fep->phy_interface);
  if (!phy_dev)
   return -ENODEV;
 } else {
  /* check for attached phy */
  //for (phy_id = 0; (phy_id < PHY_MAX_ADDR); phy_id++) {

 for (phy_id = 1; (phy_id < PHY_MAX_ADDR); phy_id++) {
   if ((fep->mii_bus->phy_mask & (1 << phy_id)))
    continue;
   if (fep->mii_bus->phy_map[phy_id] == NULL)
    continue;
   if (fep->mii_bus->phy_map[phy_id]->phy_id == 0)
    continue;
   if (dev_id--)
    continue;
   strlcpy(mdio_bus_id, fep->mii_bus->id, MII_BUS_ID_SIZE);
   break;
  }

从log 来看 用的PHY的地址ID是 00 是一个广播地址。 这个应该是硬件设计的问题。

在device tree 里面根据硬件设计配置一下PHYID 再试验一下。

或者改一下fec_main.c 从 1 开始找phy 而不是0

 //for (phy_id = 0; (phy_id < PHY_MAX_ADDR); phy_id++) {

 for (phy_id = 1; (phy_id < PHY_MAX_ADDR); phy_id++) {
