Ethernet work at 10Mbit only

dmitry chernov

Hello.

We have been working with ksz9021gn PHY connected to DM8168. But work is possible only at 10Mbps on our custom board. The link at 100Mbits and 1000Mbits are presented, but ping command is not passed. We refer to the manufacturer of the controller-he said that we have a correct scheme. We checked the frequency-all right. We have removed twice all of the components that are relevant to the PHY and PHY too. But the result did not change and we still have the 10Mbps speed only. Please help to understand what the problem is. Are we need to do something in driver? We are using last SDK without applying patches. We have some expirience working with other PHY - they had not had any problems. Problems began only when we decided to put a new ksz9021gn PHY.

Best regards,

Dmitry.

Hello,

Make sure you are testing with direct ethernet connection between DM816x board and host PC (I mean there is no ethernet switch/hub/router between).

Hello Pavel.

Thank you for reply. We'll look at the reference.

We tried to connect both through a switch or directly to a computer. The computer has a 1Gbit Ethernet. When we connect with the computer, it can be seen that the network icon in the taskbar on the right corner of computer shows the speed that we set at the command line in Linux. So actually connection which is 10Mbps or 100Mbps or 1000Mbps installed correctly at physical level. The problem is that ping possible at frequency 10Mbps only.
As for the driver, it is not clear that it should be changed, because the driver must be suitable standard.

Best regards,

Dmitry

Dmitry,

Are you using EZSDK or DVR RDK? Is the issue in u-boot or linux kernel?

Can you try with the latest u-boot code base:

EZSDK - http://arago-project.org/git/projects/u-boot-omap3.git?p=projects/u-boot-omap3.git;a=shortlog;h=refs/heads/ti81xx-master

DVR RDK - http://arago-project.org/git/projects/?p=u-boot-dvr-rdk-dm81xx.git;a=shortlog;h=refs/heads/dvrrdk_uboot_int_branch

Hello, Pavel.

A'm using EZSDK only.

1) The problem is in the kernel. At last we need good working in kernel. I've not tried the ping in u-boot. Can you advice how can i use u-boot commands to tune ethernet to check it? Can you give me reference of using ethernet under u-boot or examples?

2) Is it possible get last EZSDK version with applied patches or may be you know what file i need apply exactly to get good working of EMAC with PHY in the kernel?

Thanks,

Dmitry.

We have seen all these references some time ago and tried to apply them. But it was not help us. In all of those cases are discussed the problem about gigabit ethernet - but we not have correctly work even with 100Mbit ethernet. So, as seem to me, we have little other sort of problem.

Dmitry.

Is this the latest DM816x EZSDK 5.05.02.00?

Below is how I test my ethernet on EMAC0 (with dhcp and ping commands) in u-boot:

Net: <ethaddr> not set. Reading from E-fuse
Detected MACID:40:5f:c2:63:a2:30
Ethernet PHY: GENERIC @ 0x01

Using DaVinci EMAC device

Try first with the default EZSDK 5.05.02.00 (u-boot and kernel).

Thanks,

We'll try u-boot commands to check Ethernet.

Yes, we are using default last EZSDK 5.05.02.00 and we haven't changed sources of ethernet driver. So we have pure default ethernet sources from EZSDK 5.05.02.00.

Hello.

We have tried to use all possible ways to check possibility to work with our PHY. We have looked at the internal registers - all ones have correct settings. Additionally we have tried to change state of PHY registers. Now we get 2.5MHz for 10Mbits, 25MHz for 100Mbits, and 125MHz for 1000Mbits, but it is not to have ping PHY at 100 and 1000MHz yet. As i have said early, we have direct connection with our PC. The phisical connection is working correctly, because we can see at the lower right corner of PC connection status (10, 100 or 1000).

1) We have not tried to check network under u-boot. We are using ETH1, but where in sources we need to switch on ETH1?

2) How can we check EMAC internal loopback and PHY internal internal loopback?

3) May be anybody has any other idea to tune our PHY?

Dmitry.

hello Dmitry,

Could you download ethtool and show us the result when setting 10/100/1000 with auto negotiation on/off ?

Show the status after your each setting. Thanks

Note: please set your PC with auto negotiation without speed limit...

hello

after each "ethtool -s eth1 speed xxx duplex full autoneg xx", please add "ethtool eth1" ,

and check if the status is the same as your connected machine( verify by led or else...).

And show the result.

Your connected machine is auto negotiation on. right?

please also try this case

ethtool -s eth1 speed 1000 duplex full autoneg on

ethtool -s eth1 speed 10 duplex full autoneg off

ethtool -s eth1 speed 1000 duplex full autoneg on

and show me the results in both machines ~

hi Dmitry,

please try to ping yourself (192.168.1.185) in case of failure in ping remote side(192.168.1.187). And show the result.
After checking in active mode, let's change it to passive mode.
Do the operation in the above post in remote PC (Note: make sure the 8168 is in the state of auto negotiation on without speed limit) and show the result.
