Ethernet-over-USB: no ip assigned with kernel 4.1.13-bone-rt-r17

Hi

I’m trying to write a module for a real-time kernel. Following the instructions on https://eewiki.net/display/linuxonarm/BeagleBone+Black, I compiled and deployed a 4.1.13-bone-rt-r17 kernel to an sd card with a Debian GNU/Linux 7 BeagleBoard.org Debian Image 2015-03-01.

Before, with kernel 3.8.13-bone70, everything was working perfectly fine. However after upgrading the kernel, my desktop (running Linux Mint) no longer receives an ip address.

ifconfig beaglebone:

usb0 Link encap:Ethernet HWaddr a2:29:c5:ee:bf:e6
inet addr:192.168.7.2 Bcast:192.168.7.3 Mask:255.255.255.252
inet6 addr: fe80::a029:c5ff:feee:bfe6/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:1 errors:0 dropped:0 overruns:0 frame:0
TX packets:37 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:76 (76.0 B) TX bytes:9408 (9.1 KiB)

ifconfig desktop:

eth1 Link encap:Ethernet HWaddr 84:eb:18:ae:cb:aa
inet6 addr: fe80::86eb:18ff:feae:cbaa/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:37 errors:0 dropped:0 overruns:0 frame:0
TX packets:2 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:7262 (7.2 KB) TX bytes:268 (268.0 B)

manually assigning an ip does not do the trick. When pinging the desktop from the beaglebone (with or without manually assigning an ip), i can catch the requests using tcpdump. The beaglebone does however not receive anything, no answers to pings, nothing showing up in tcpdump.

I already spent hours trying to figure out the problem here, any help is greatly appreciated!

Fixed in:

https://github.com/RobertCNelson/ti-linux-kernel-dev/commit/1d9085bfb11e9e35ab0f4262799c8c801219a84f

r24.3

feel free to upgrade to:

4.1.13-ti-rt-r35

Regards,

Have you loaded the g_ether kernel module on the beaglebone ? When building your own kernel, this is something you have to take care of yourself .

4

Thanks, I’ll try that.

5

I actually thought, it were a problem with g_ether and spent hours trying to fix that. However as I used Robert Nelsons patches, everything was fine there. I’ll try the updated kernel.

6

Sorry missed the “bone”

r17 has that fix too:

https://github.com/RobertCNelson/bb-kernel/blob/am33x-rt-v4.1/patches/defconfig#L4305

Now i’m not sure…

What shows up on the beagle’s journal?

7

journal as in journalctl? doesn’t seem to be included. but here’s what I found in dmesg that seemed relevant:

8

It always just worked for me. g_ether that is. Of course, I do not use systemd . . . no idea if systemd requires any special voodoo to get g_ether working, or not.

One thing to note though Fabian. You can use ./build_deb next time you build a new kernel, copy the deb over, and just sudo dpkg -i linux-image*.deb.

I only mention that in case you were unaware of that. . . but this way has the added benefit of being easier, and installing everything you need. Once you get a base rootfs running. It’ll work on all the base images too, of course.

Sorry for the cutoff on the beaglebone output, I’m currently using minicom…

@William: that’s actually a very good idea, thanks! I’ll try installing the kernel like that from now on.
I tried to turn off systemd, following your instructions in another thread. Didn’t help though.

12

ahh, looks like a race between usb0 & udhcpd..

is /opt/scripts/ up to date?

cd /opt/scripts/
git pull

Regards,

13

it should be now. however I don’t currently have network access on the beaglebone, I therefore cloned https://github.com/RobertCNelson/boot-scripts to my desktop and copied it over.

14

I restarted from a backup, updated /opt/scripts/ with kernel 3.8 and installed the new kernel using dpkg as William suggested. No luck.

restarting udhcpd also does not do the trick. Any ideas?

Thanks for your help!

15

SO is the hardware detected on both sides now or what ? If its just a dhcp thing, you can always just use static IPs. Which is exactly what I always do . . .

16

no. still, the host gets not assigned an ip address. if I assign one manually, doesn’t change the fact, that somehow messages don’t get through to the bone…

I’m stuck

17

any ideas?

18

seems to have been a driver compatibility problem on the host side (linux mint 17.2, kernel 3.16). an update to linux mint 17.3 with kernel 3.19 solved the problem.

19

I experienced the same issue:
BBB runs in 4.1.15-ti-rt-r43
Host runs in 4.2.5-300.fc23.x86_64.

I thought I had network setup issue in host PC. So I checked the route, IP, net mask and gateway in host PC under 3.8 kernel, where host PC get connected to USB gadget ethernet correctly.

But even I manually applied this setting for 4.1.15-ti-rt-r43. The connection is still broken. I wonder if/what DHCP server runs in 3.8? Is it possible that kernel USB gadget driver is broken in 4.1?

thanks,
Ricky

I also tested in different host in Mac OS 10.11.3. It still doesn’t work even after manually assign static IP, network mast in host. The hosts works fine with 3.8 kernel in BBB.
