LS1088ARDB - Ethernet Link Status

mloder — Tue, 18 Jun 2024 18:21:02 GMT

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.

Regards

Mike

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.

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

Thanks a lot
