Beaglebone Black : miss mii.ko and usbnet.ko so no USB to ethernet converter work !

Hi guys !

I need a second ethernet interface on my BBB … so I am using an asix usb to ethernet converter…

On my linux desktop I discovered that mii and usbnet modules access to the module asix ( lsmod ), but these modules miss from my BBB debian image !

so ifconfig don’t recognize a second ethernet interface … I think this is the reason cause it doesn’t work

I just set the interfaces file and “lsusb” command recognize the USB to ethernet converter.

Could you tell me where I can find an image with mii.ko and usbnet.ko modules ?

Or Could you tell me how to build these modules correctly ?

I tried to build mii.ko and usbnet.ko but they don’t work

Thanks a lot guys !

First off, you should probably tell us what you have running for Linux on your beaglebone black. Debian ? Is it custom, and if so where did it come from ?

Passed that, usbnet is probably on your system.

william@xanbustester:~/can-dev/can-web$ sudo find / -name usbnet.ko
[sudo] password for william:
/lib/modules/4.2.0-rc4-bone2/kernel/drivers/net/usb/usbnet.ko

As is mii . . .

william@xanbustester:~/can-dev/can-web$ sudo find / -name mii.ko
/lib/modules/4.2.0-rc4-bone2/kernel/drivers/net/mii.ko

Anything else ?

Hi William, I have different Linux versions.

  1. 3.14.4.1-bone-armhf.com

/lib/modules/3.14.4.1-bone-armhf.com/kernel/drivers/net/usb/usbnet.ko

But it doesn’t have mii.ko

  1. 3.8.13-bone70 ( Debian Pass: tempwd ) from the beagle website:

No usbnet.ko , no mii.ko

I used find command on my pc and I have 3.16.0-48-generic ubuntu which has both modules

So could you tell me where did you download your image ? Thanks a lot

These are "built-in" with 3.8.13-bone70 as nfs root is very common..

Download and use, whichever official image you like. Those armhf.com images are not official.

Hi William

“2) 3.8.13-bone70 ( Debian Pass: tempwd ) from the beagle website”

This one is the latest official image I found,I downloaded it from the debian image link in the official website. In this one I didn’t find mii.ko , only usbnet.ko.

I could try other images… but I have no idea if they have these modules

I suppose I must compile another kernel like yours.

I tried another official debian image, 4.1 kernel… but no modules…

Anyway thank you guys for your support.

I will appreciate any suggestions

Thanks a lot again

Hi William

"2) 3.8.13-bone70 ( Debian Pass: tempwd ) from the beagle website"

This one is the latest official image I found,I downloaded it from the
debian image link in the official website. In this one I didn't find mii.ko
, only usbnet.ko.

mii.ko is 'built-in' for nfs root...

I could try other images.... but I have no idea if they have these modules

I suppose I must compile another kernel like yours.

I tried another official debian image, 4.1 kernel... but no modules....

Anyway thank you guys for your support.

I will appreciate any suggestions

What's the actual issue?

Sorry Robert , maybe I don’t understand.

You told me I must install nfs on my Beaglebone. ( nfs = network file system isnt’t it ? ) .
If this is the only way to have mii.ko I will do it.

I thought there was a "ready to use " beaglebone image with mii.ko

If the answer is no I will install nfs like you suggested.

I quick looked in the web and lots of guides lead to your name hehe ^^

Thanks again !

No that's not what i said..

I said "mii.ko" is "built-in" for "nfs" "users"... Therefore your not
going to find the "mii.ko" module when you search /lib/modules/

I thought there was a "ready to use " beaglebone image with mii.ko

If the answer is no I will install nfs like you suggested.

I quick looked in the web and lots of guides lead to your name hehe ^^

Since "mii.ko" is built-in, there is nothing stopping you from using it...

A ok Robert, now I understand what you mean.

So why the USB to Ethernet adapter doesn’t work ?

debian@beaglebone:/etc/network$ sudo ifup eth1
Cannot find device “eth1”
Failed to bring up eth1.

The ifconfig commadn doesn’t show eth1 .

In my ubuntu desktop I got both modules mii.ko and usbnet.ko and this USB to Ethernet adapter works … so I asked you where to find these modules …

Thanks a lot Robert

i bet it says "rename0"

sudo ifconfig -a

I fixed that a while ago, but if your still running the 2014.05 (cat
/etc/dogtag) then that's why..

So fast Robert :slight_smile:

I will be back on the BBB in 2 days.

I will check this as soon as possible and I’ll tell you what’s going on.

It’s working in this test version ! :slight_smile: I get both images from the official site

How could I fix BeagleBoard.org Debian Image 2015-03-01 ?

That’s just udev persistent network names. Look under /etc/udev/rules…

15

Bingo Robert !

Sorry for time I took but I was very busy … the problem was exactly the udev/rules … the system recognized the asix mac address but assigned him the eth2 interface … the eth1 was assigned to another asix mac address, not the mine. I changed the assignement and now everything works.

So Robert … I can only say " thank you " :slight_smile:

Now I am fighting with xenomai kernel … compile ok , install ok but I have boot trouble…

Maybe I will open another topic about this

Thanks again

Matt
