P1021rdb not able to ping using eTSEC2 in SGMII mode

Hi,

I'm having a problem not being able to ping to an ipaddress. I'm wokring on P1021rdb PowerQUICC based processor, configured eTSEC2 in SGMII mode. The link shows being "Link - Up" but unable to ping

I'm only using ethernet 1 (eTSEC2 in SGMII mode)

Please find all the info regarding the board bring up, uboot output, dts,
bootUp file and Application which configures the ethernet is attached
Please go through the files.

==============
After board bringUp, we created an application which configures the ethernet,
we are using ELECTRICAL SFP (Finisar).
Application successfully configures the ethernet and the Link is Up,
but not able to use PING

Attached the BootUp file and Application Output File. Please check the files

Found the solution for the error.

I was going through the Gianfar.c and in the gfar_start() function I've observed that the below two lines of code which enables the queues were commented.

gfar_write(&regs->rqueue, priv->rqueue);
gfar_write(&regs->tqueue, priv->tqueue);

i don't remember why it was commented out, but thank you for the support given

Please define enet1 similar as the following.

enet1: ethernet@b1000 {
phy-handle = <&phy0>;
tbi-handle = <&tbi1>;
phy-connection-type = "sgmii";

}

 

mdio@24000 {

phy0: ethernet-phy@0 {

interrupt-parent = <&mpic>;

interrupts =<3  1 0 0>;

 reg = <0x0>;

  };

...

Sorry i did not provide complete imformation

We are using Finisar (electrical) phy, where it is being configured via I2C.
For data transfer we are using SerDes in SGMII mode and eTSEC2 with internal TBI PHY is used.

Hello solomon,

 

You need to contact the PHY manufacturer for driver availability.

Please refer to https://elixir.bootlin.com/linux/latest/source/drivers/net/phy/mdio-i2c.c

You need to replace phy_read()/phy_write in PHY device driver with i2c read/write functions.
