HI Tirtha： I think you have to also check the USB driver? Try to run dmesg to if there any useful info

Hi All,

I was trying booting 3.1.5 linaro kernel with wheezy debian filesystem on pandaboard, but I found ethernet is not working.

On further check I found, there is no net interface under /sys/class/net/ except loopback. Though I have checked kernel config is having scm91x (and scm911x) enabled. I am really not sure about net driver details but I could not see these drivers are getting probed at kernel boot.

Whereas, I have taken 3.2 kernel from kernel.org and it worked perfectly fine and there is no change in defconfig file from 3.1.5.

I also observed the code structure for ethernet drivers are different between 3.1.5 and 3.2 but driver files are same except *ndo_set_rx_mode* has been implemented in 3.2 in place of * ndo_set_multicast_list.*

any idea, about this problem? is it known??? Or is it something I am missing??

Thanks in advance

Ok. I never noticed this. Just checked the schematic of Pandaboard. Thanks a lot.

I think then I need to enable CONFIG_USB_NET_SMSC95XX in defconfig, right?

I will check and come back with result.

thanks guys.

The Ethernet port on the Pandaboard comes from an SMSC LAN 95xx chip – which is connected to the Pandaboard over USB.
