ethernet (usb0) not working

[lewuskip]

Hi Max,

I have managed to build kernel and filesystem using your repos but having problem with ethernet over USB.

ifconfig lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:182 errors:0 dropped:0 overruns:0 frame:0 TX packets:182 errors:0 dropped:0 overruns:0 B) TX bytes:19152 (18.7 KiB)

usb0 Link encap:Ethernet HWaddr 32:FA:DA:3C:96:61

I ma using static addresses, board is connected to other computer using HUB and third computer running wireshark. Aparently nothing comming out from the board. I power up the board using USB.

Any sugestion?

thx, Piotr

Looks like USB hub works fine, I have connected USB mouse and has been successfully detected by linux, but ethernet still not sending anything.

More comments :)

I have tested Angstrom demo image and got ourput after lsmod

root@beagleboard:~# lsmod Module Size Used by bufferclass_ti 4596 0 omaplfb 8749 0 pvrsrvkm 126503 2 bufferclass_ti,omaplfb rfcomm 33484 0 ircomm_tty 30305 0 ircomm 16429 1 ircomm_tty irda 162973 2 ircomm_tty,ircomm ipv6 249063 8 hidp 11193 0 l2cap 30104 4 rfcomm,hidp bluetooth 49221 3 rfcomm,hidp,l2cap rfkill 14838 2 bluetooth minix 25759 0 rtc_tw 4451 0 rtc_core 12535 1 rtc_twl mt9t112 9246 0

First I would expect something like smsc95xx module, second I got nothing when execute it from image generated by buildroot.

Hi Piotr,

Which Ethernet USB adapter are you using?

Hi Max,

I am talking about the Etherent on the board (beagleboard-xm revC) which is connected to the one of the USB port on the hub on the board. This is smsc95xx chip. I have a strange observation, from the user/software point of view nothing is wrong, I can up the usb0 ehternet interface with static addresses and looks ok. Additionally I see a small amount of packets RX/TX but I dont see anything on the wire using wireshark.

Dont worry bout that now as I will do some more additionally investigation for next few days including testing yout kernel and filessystem provided on your website. Unless you got some quick thoughts I can check.

I will put more comments latter this week.

Thx, Piotr

Hi Max,

I have tested yout uImage and rootfs full (link for rootfs reduced doeasnt seems to work anymore) and got the same results so looks like I am doing something fundamentaly wrong :)

Once the board is booted I type ifconfig usb0 192.168.1.3 netmask 255.255.255.0 up

and expecting that ethernet over usb on the board start to work but then I monitor TX and RX packages using ifconfig and all counters are 0`s.

This is the last lines after dmesg and ifconfig output

Any idea ?

Please try to use eth0 instead of usb0 and update your /etc/network/interfaces with proper network configuration.
