Interesting, I have been playing with BeagleBone Rev5 for few months, I just received my new Rev A6 beagleBone, I put SDcard that works great on Rev A5, started and … I can not see my BeagleBone on my network ( ethernet cable is connected :)).
I can connect to BeagleBone via USB port and minicom. Here are outputs of some commands:

ifconfig

Hmm, what is the problem, hat changes were done to Rev A6 that prevent me from connecting to internet, any ideas??
Any idea how to fix it?

Thanks

UDEV is playing tricks. Did you use the same card or image ?

On the first bone udev saved the MAC address and assigned that one to eth0; now it sees another MAC and assigned to eth1 and so forth.

Check /etc/udev/rules.d for a file named net-persistent-rules or something. Just delete (or edit to remove rules on the MAC) that file an reboot.

hi…
I also getting some problem regarding USB in beaglebone A6. I have a driver which uses feature of /lib/modules/3.2.18/build, but I checked that this directory not exist in angstrom and ubuntu both, therefore at time of installation following problems:

make -C /lib/modules/3.2.18/build M=/home/root/VCOM-Integration-Kit_v4.10.31_Release/driver
make: *** /lib/modules/3.2.18/build: No such file or directory. Stop.
make: *** [all] Error 2
must be signed in as root
copying vcom.ko to /lib/modules/3.2.18/kernel/drivers/usb/misc
install -m 644 vcom.ko /lib/modules/3.2.18/kernel/drivers/usb/misc/vcom.ko
install: cannot stat `vcom.ko’: No such file or directory
make: *** [install] Error 1

can anyone solve these issue. My project almost completed but for this issue, I am not able to do more.

Thanks
