AM6442: ENABLING IP ADDRESS IN ETH1

Radhika Pradeep
Prodigy 80 points
Part Number: AM6442

Hi ,

We have a board with am6442 chip with dual mac running processor sdk 8.0 device tree file.

We can see both the eth0 and eth1 ethernet  while running the ifconfig command .

eth0 is getting the ip address and working fine but eth1 is not gettiing the ip address.

When we try to activate the network with 'ifup' command ,it is showing the error below.We have added the pinmuxing in the

device tree file.

***************************************************************************************

ERROR

root@am64xx-evm:~# ifup eth1 up
[ 100.291674] am65-cpsw-nuss 8000000.ethernet: phy /mdio-mux-1/mdio@1/ethernet-phy@3 not found on slave 2
ifconfig: SIOCSIFFLAGS: No such device

*******************************************************************************************

Could anyone please suggest any method or steps to solve this issue.

Any help is appreciated.

Thanks and Regards,

Radhika

    Hi,

    Could you attach (not cut and paster) the boot log please? The mdio driver usually reports the PHYs it finds on the bus. The reason the PHY is not found could be several things most HW related. Does the boot log show expected PHYs at expected addresses? Is the PHY being identified with the correct Driver?

    Best Regards,
