Getting USB devices to work on BeagleBoard xM

Getting USB devices to work on BeagleBoard xM

[Jeremy Cole-Baker]

Hi,

I've managed to build a couple of different recipes for my BeagleBoard 
(BeagleBoard xM Rev C), and also had a go at customising it.  I think 
I've tried core-image-minimal and core-image-basic.

The build works OK, and I can set up my micro SD card and get it to 
boot. I see lots of messages about loading drivers during boot, and I 
can log in to linux.

However, the USB devices don't seem to be working. The built in 
USB-Ethernet isn't there, and when I plug in a USB stick nothing happens 
- nothing in /dev/ and no messages in the system log.

I don't know whether this is something I missed in the build, or some 
configuration I need to do. I also don't know whether it is specific to 
the Beagle or a general problem. Unfortunately I am new to Kernel builds 
and device drivers.

Here's what I've looked into:

The boot-up messages indicate that the USB drivers are loaded, e.g.:

<snip>
usbcore: registered new interface driver usbfs
usbcore: registered new interface driver hub
usbcore: registered new device driver usb
...
usbcore: registered new interface driver smsc75xx
usbcore: registered new interface driver smsc95xx
...etc

(I think smsc95xx is the USB-Ethernet chip on the beagle board xM).

ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver
ehci-omap: OMAP-EHCI Host Controller driver
ehci-omap 48064800.ehci: EHCI Host Controller
ehci-omap 48064800.ehci: new USB bus registered, assigned bus number 1
ehci-omap 48064800.ehci: irq 93, io mem 0x48064800
ehci-omap 48064800.ehci: USB 2.0 started, EHCI 1.00
hub 1-0:1.0: USB hub found
hub 1-0:1.0: 3 ports detected
usbcore: registered new interface driver usb-storage
musb-hdrc musb-hdrc.0.auto: musb_init_controller failed with status -6
mousedev: PS/2 mouse device common for all mice
...Etc

There's a modprobe error which occurs a couple of times:

udevd[71]: starting version 175
modprobe: chdir(3.10.11-yocto-standard): No such file or directory

I also saw errors from the ethernet subsystem (?), along the lines of 
"eth0: device not found" and "usb0: device not found". This occurred 
during boot and also when I used "ifup eth0". I'm actually seeing a 
different error now: "ifconfig: SIOCGIFFLAGS: No such device". In either 
case, I think it's because something to do with the actual USB hardware 
is missing or not configured.

"lsmod" shows no modules loaded, i.e.:

root@beagleboard:~#lsmod
Module Size Used by
root@beagleboard:~#

Does this mean that the various device drivers, etc, above are built in 
to the kernel?

Any suggestions for how to diagnose / fix this problem? Anybody else 
have experience with the BeagleBoard xM? I'm a bit lost.

Thanks!

No USB devices on BeagleBoard xM!

BeagelBoard xM.

Doesn't seem like you have modules installed in your rootfs ^^^

If you build core-image-minimal, you then need to extract the modules from a 
tarball you got in the deplot area...

Re: No USB devices on BeagleBoard xM!

[Jeremy Cole-Baker]

Hi, thanks for your reply.

I did have a modules file from the build, which I installed on my root 
fs as follows:

tar x -C _root/ -f 
modules–3.10.11+git0+363bd856c8_702040ac7c-r0-beagleboard-20140415194907.tgz

(_root is a link to the correct partition on the flash card). The file 
contained a number of directories and files which were installed under 
/lib/modules/3.10.11-yocto-standard/. I have verified that these were 
copied correctly.

Could I be missing one or more modules, because I haven't selected some 
option in the build somewhere?

Is there any way to find out what module it is trying to load (i.e. when 
it says "no such file or directory")?

I think you are seeing this bug
https://bugzilla.yoctoproject.org/show_bug.cgi?id=5211

I did not manage to get usb working with the instructions in the bug
thou.
