PROCESSOR-SDK-AM62X: the ethernt link is up but ping doesnot work

Part Number: PROCESSOR-SDK-AM62X

Hi TI,

we are using DP83822 PHY for our developement. with the following configuration

rgmii-rxid , 100Mbps/Full - flow control rx/tx.

we are using the default dtsi which comes with EVAL board AM62X.

Even though we are using only one PHY (eth0 and connected to RGMII1), However when ever we remove the ethernet cable it says "eth1 is down" instead of "eth0"

we can see from our schematic we connected to only RGMII1.

if we remove ethernet1 and RGMII2 from dtsi file, then even the eth0 is getting removed.

could you please help us in resolving the issue.

Thanks and Regards,

Swapna

Hi,

Could you please attach your schematic snippet showing the CPSW interface(s).

Could you also please attach your boot log?

Also please attach the results of the following commands:

- ifconfig -a

- ethtool eth0

- ethtool eth1

- ethtool -S eth0

- ethtool -S eth1

I would also recommend setting the link up between your board and a Linux PC where wireshark can be run. This will tell us if packets are at least being transmitted from your board.

Best Regards,

Schuyler

Hi Schuyler,

From the last post we have disabled the eth1 and only enabled eth0.

The schematic snippet is as below:

One more observations is, the driver is displayed as GENERIC PHY and not DP83822.

Hi,

One question to begin with the PHY driver not being identified. Did you use the TI defconfig for you kernel configuration? One reason that the generic driver is being used if because the kernel does not access to the PHY driver.

The other thing I see is that there are DP867 timing references. I will need to check with a colleague if the DP83822 requires the timing parameters. Is this what you are calculating as result of layout timing analysis?

Best Regards,

Schuyler

Hi Schuyler,

We have enables the DP83822 Driver from menuconfig and it is getting reflected in .config file, but still show as GENERIC PHY.

Hi,

This is confusing that the PHY is not being identified. Since the link is detected and up the Generic PHY is at least able to communicate over the MDIO link. I will need to check with the TI PHY team to provide some clues on what to look at next. I am still working the timing question, I hope to have an answer tomorrow.

Best Regards,

Schuyler

Hi Schuyler,

Any updates on the current issue we are facing, as this issue becoming critical to our release.

Thanks and regards,

Hi,

I think we need to resolve the generic PHY detection issue since if you want to set PHY parameters you will need the driver detected.

I noticed that you said that phy-tool was returning 0 or 0xFFFF, does mii-tool return similar results?

Could you try running the TI default kernel from the SDK that you are using? All the TI phys are by default configed into the kernel. BTW, which TI SDK version are you using?

Best Regards,

Schuyler
