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.: 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! Jeremy Cole-Baker
