Hi All,
I have a custom board using AM3358, which is very similar to beaglebone. I
am having trouble with bringing up ethernet.
This is what I get when I execute *dmesg | grep mdio*
*[ 4.412295] davinci_mdio 4a101000.mdio: davinci mdio revision 1.6
*
*[ 4.418430] davinci_mdio 4a101000.mdio: no live phy, scanning all
*
*[ 4.424791] davinci_mdio: probe of 4a101000.mdio failed with error -5
*
*[ 10.044897] libphy: PHY 4a101000.mdio:00 not found
*
*[ 10.049713] net eth0: phy 4a101000.mdio:00 not found on slave 0
*
*[ 12.258086] libphy: PHY 4a101000.mdio:00 not found
*
*[ 12.262928] net eth0: phy 4a101000.mdio:00 not found on slave 0 *
I am using a custom linux image which was built using buildroot. I am able
to get ethernet working with my same linux image on beaglebone. To me it
seems like its a hardware issue.
Please see my Ethernet schematics. I am using a SI-52003-F as my ethernet
connector for my POE circuit (which is not shown here).
Any help would be greatly appreciated.
Thank you,
Samer
