LS1088ARDB - Ethernet Link Status

[mloder]

Hi NXP Support,

I am struggling with the LS1088ARDB development board. Using the default configuration for the yocto build for the board I can get networking operational. However, ETHTOOL Reports the link status as yes always regardless if an ethernet cable is plugged in or not.

- Boot Up

- Run `ethtool eth0`, link detected reports yes with no ethernet port plugged in.

Settings for eth0:
        Supported ports: [  ]
        Supported link modes:   Not reported
        Supported pause frame use: No
        Supports auto-negotiation: No
        Supported FEC modes: Not reported
        Advertised link modes:  Not reported
        Advertised pause frame use: No
        Advertised auto-negotiation: No
        Advertised FEC modes: Not reported
        Speed: 1000Mb/s
        Duplex: Full
        Auto-negotiation: off
        Port: Twisted Pair
        PHYAD: 0
        Transceiver: internal
        MDI-X: Unknown
        Link detected: yes

We need a way to know what ports have physical cables plugged in, as well as udev rules that trigger when cables are plugged in and removed. udev is not reporting any driver state changes on cables being plugged in.

you can check it at MAC level, please use the next command:

restool dpmac info dpmac.<mac number>

To determine what macs you have execute:

ls-listni

please let me know the results

@LFGP  or @mloder , could you help me resolve this one?

Thanks a lot

try to use the command

$ ip monitor all

 it is used to get real time link state.

please check the info in the next link, it could help with your objetive

Hi LFGP,

Thank you for the help, however, I tried the command, it only works with DPMAC2 this is also the only port ethtool works on. DPMAC3-10 does not report at all with that command there is no output.

Regards

Mike
