AM620-Q1: Ethernet PHY configuration issue.

Jim Meyer

Part Number: AM620-Q1
Other Parts Discussed in Thread: DP83869HM

Tool/software:

We have a custom board that has two ethernet ports. When I enable them in the configuration files, eth1 is configured as 10 Mbps and half duplex while eth0 is configured as 1000 Mbps and full duplex. We've checked the strapping pins and they seem to be correct (one LED pin is floating on both transceivers).

I was asked to start a separate thread so the PHY team might offer an explanation for why eth1 is not configured and the PHY registers are not readable/writable.

With "mdio", I see the same:

Thanks!

Hi,

Yes starting another thread was recommended but you needed to set the responsible org to Ethernet which is different from the Sitara org. I will move the thread to that org, it make take a day or two since this end of a holiday week.

Best Regards,

Schuyler

Hi,

Most of us were out last week, I hope to get a colleague from the PHY team to assist.

Hi Jim

I apologize as I thought the PHY you are using was a TI PHY. I looked through your other threads and I maybe missing it. What are you using for the PHY?

Best Regards,

Schuyler

Schuyler,

The transceiver chip is DP83869HMRGZR. It is TI (I believe).

Hi Jim!

I'm an Applications Engineer for the Ethernet team, I will be assisting you with this query. From the above I understand that we have two ports, both the DP83869HM, and we want both ports to be configured in the same mode. Port 0 is operating as expected but Port 1 is not configured correctly and is missing register read/write access. Please let me know if my understanding is correct.

Could you do the following for me?

Could you confirm if this is a Linux environment?
1. If so, could you run the following command to confirm the Kernel version?
  1. uname -r
Upon board boot-up, could you run the following command to confirm if the PHY driver was loaded correctly.
1. dmesg | grep -i mdio
2. Please see section 4.1.1 of the attached Appnote (it is currently in the process of being released to TI.com, the attached is a local copy)
  1. [Draft] SNLA450 How to Integrate Linux Driver into your System.pdf

Alvaro,

Yes, that is correct! I am able to "ping" both ports but eth1 is operating at 10Mbps and half duplex while eth0 is operating at 100 Mbps and Full duplex. I believe they are both "strapped identically". My USB to Ethernet adaptor is 100 Mbps.

Unfortunately, I have not been able to boot fully on our hardware yet (another thread is looking into this) but I can use the u-boot shell:

I can verify the ping using Wireshark (both eth1 and eth0).

Here's the latest boot log:

Hi Jim,

Are you able to read the PHY's registers from uboot? Please see this [FAQ] for more information.

Could you read Registers 0x6E and 0x6F for both ethernet PHYs on your board? This would confirm if the strapping is the same between them. Please note that 0x6E and 0x6F are [FAQ] extended registers.

Regards,

Alvaro

I'm not sure what I'm reading on eth1.

I'll see if I can read the other register you identified.

I'm not sure if I did this correctly but here's what I see when I try to read those extended registers:

Hi Jim,

Thank you for trying and providing the register dump. Your command was almost correct. Please see the commands below, please do this for both PHYs.

mii write 0 0x0D 0x001F

mii write 0 0x0E 0x6E

mii write 0 0x0D 0x401F

mii read 0 0x0E

Regards,

Alvaro

Alvaro,

I get the same results with 0x401F.

I see the last command was incorrect but previous correct attempts showed the same.

Hi Jim!

Apologies for the long response time. I just noticed the reads for Eth1 (mii dump 1 0 = 0x0000 & mii dump 1 1 = 0xFFFF ) are strange.

Could you read registers 0x4 & 0x9 for both PHYs? These contain the speed advertisements. How are the MDC/MDIO lines connected between the two PHYs and the SoC?

Regards,

Alvaro

Alvaro,

They’ve got this project on “pause” for the moment so I can’t immediately respond. I’ll address this when I can. If there is anything you can do on your side with the information I've already provided, it would be appreciated.

Thanks!

Excellent! I may be able to follow up next week.
