IMX6-LAN7500 interface not able to fetch

srikanthmediset — Fri, 25 Aug 2017 11:47:22 GMT

Hi,

I was working on an customised iMX6 board with two ethernet hubs.One ethernet is detecting as eth0 and was working fine.The second was an POE ethernet of chipset LAN7500.When I try to config this ethernet it was throwing an error like

ifconfig eth1

eth1: error fetching interface information: Device not found

When I go to the following path cd /etc/udev/rules.d/70-persistent-net.rules I was able to see the eth1 name for that interface.

Now,I am not able to understand what is the conflict here I was facing.

Regards,

srikanth.

It seems there is no driver for LAN7500 in your system. Please grep dmesg for "eth1".
You need to add the driver to the kernel.

Have a great day,
Victor

Hi victor,

LAN7500 driver was inbuilt in the kernel. When I boot the board I was getting the log as below

usbcore: registered new interface driver smsc75xx
ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver

The above lines doesn't mean that the driver is ready to work????

After entering into root when I run lsusb I was getting like

Bus 002 Device 002: ID 0424:2514 Standard Microsystems Corp. USB 2.0 Hub

where 0424 is the vendor id for smsc7500.

Regards,

srikanth.
