IMX8MQ LEDS on Ethernet ports stays on even after cable is plugged out

Hi All,

  • We are working product based on IMX8MQ.
  • We are using kernel 4.14.98. 
  • We have two Ethernet ports. One Ethernet port is connected via Marvell switch. Second is USB to Ethernet port.  
  • In both ports we observed that sometimes after cable is plugged out LEDS ok RJ45 kept blinking. Also Ethtool shows link detected as yes. 

This is critical issue. Has any faced such issue before? Any suggestion or pointer related to this issue will be appreciated. 

Thanks,

Jemish

Hi @jemish_1990 !
Thank you for contacting NXP Support!

Sorry, I cannot reproduce the error on our evk.

Try to see if is any bridge configured, and check and compare your schematic with the evk schematic.

Sorry for the mistake!

Best Regards!

Hi @jemish_1990 !
Thank you for contacting NXP Support!

What adapter are you using?

I will try to reproduce the error on a evk board.

I know that is not the same, but I can try.

Best Regards!
