Ethernet issues

Lajos Rancz
Expert 1065 points

Hi all,

We are using a DM8148 based board (own hw) and the ethernet interface is untrustworthy. Usually it's working good, but sometimes going wrong. I've tried to ping a site from UBoot and I've got the following error message:

failed to read bmcr
Using cpsw device
ping failed; host 10.10.22.1 is not alive

What's wrong?

Regards,
Lajos

    The error log mentions that CPSW driver is not able to read the PHY device register via MDIO. Can you check whether PHY id is properly populated in the CPSW slave structure? Other leads can you probe your MDIO clock and data and verify whether it all good
