Bbb sniffer

On a Linux desktop

mkdir ~/bbb cd ~/bbb

wget http://debian.beagleboard.org/images/bone-debian-7.5-2014-05-14-2gb.img.xz
md5sum bone-debian-7.5-2014-05-14-2gb.img.xz

(result should be 35877ce21e8ed0eb1bdc6819ad71c317)

xz --stdout -d bone-debian-7.5-2014-05-14-2gb.img.xz | sudo dd of=/dev/sdX bs=4096
sync

Remove the sdcard.

wget https://github.com/RobertCNelson/linux-dev/archive/3.8.13-bone50.tar.gz
tar xzvf 3.8.13-bone50.tar.gz 
cd linux-dev-3.8.13-bone50/

If needed, modify tools/host_det.sh so that it detects your Linux distribution.

./build_kernel.sh

This script will eventually tell you to run commands to install missing packages, e.g.:

sudo apt-get update
sudo apt-get install device-tree-compiler lzma

./build_kernel.sh

Patch and rebuild USB gadget modules:

cd KERNEL/drivers/usb/gadget/
wget https://raw.githubusercontent.com/dominicgs/USBProxy/master/doc/inode.c.patch
patch < inode.c.patch
cd ~/bbb/linux-dev-3.8.13-bone50
./tools/rebuild.sh

Insert and mount the sdcard (e.g. to /mnt/rootfs).

cp ~/bbb/linux-dev-3.8.13-bone50/KERNEL/drivers/usb/gadget/*.ko /mnt/rootfs/lib/modules/3.8.13-bone50/kernel/drivers/usb/gadget/

Modify the /mnt/rootfs/opt/scripts/boot/am335x_evm.sh file so that the usb0 related lines are commented out.

Unmount the sdcard, plug it in the BBB, and power it on.

On the BBB

depmod -a

sudo apt-get install libudev-dev

mkdir sniffer cd sniffer wget https://github.com/libusb/libusb/archive/v1.0.19.tar.gz tar xzvf v1.0.19.tar.gz cd libusb-1.0.19/ ./bootstrap.sh ./configure make make install

mv /etc/ld.so.conf.d/libc.conf /etc/ld.so.conf.d/aa_libc.conf ldconfig

And install/run USBProxy as explained in the README.md.
